If you enjoy being on or in the water, California's Channel Islands offers some of the best natural beauty the world has to offer. It's life source?...cool Pacific Ocean water.

Sunlight filtered by the canopy becomes an array of thin green-yellow splinters illuminating kelp fronds and fish immediately below. Juvenile calico bass and small kelpfish are well-camouflaged between brown kelp stipes and tangled blades. Small groups of sardines, almost invisible against the blue sky above, dart inches beneath the surface where the canopy clears. Slight surge rocks the entire forest gently back and forth.

Dominating the scene are columns of giant kelp and rocky reefs and walls carpeted in short palm frond kelp and clusters of red algae and speckled with sponges, anemones, gorgonian and deep-water hydrocoral. Dropping down only halfway to the reefy bottom below you can navigate to shore, suspended quietly among the towering plants.

Bright individual garibaldi and scattered schools of blacksmith, perch and bass swim busily over the reefs while a few nocturnal lobster and horn sharks are still seeking shelter for the day in the form of holes and ledges. Occasional open sand areas within the kelp bed, accompanied by clearings in the canopy above, seem like huge well-lit rooms in an immense shadowy building and attract large swirling schools of jack mackerel, sunbathing sea lions and the occasional Pacific barracuda.

Sound good? This describes some of the finest diving in the world! The California kelp beds, vibrant with life, offer a multitude of water based opportunity.

The Changing of the Seasons

California may not have easily recognizable seasons, but on the ocean, the changing of the seasons is definite and clear. The Humboldt and Davidson currents that parallel the California coast transport cool water from the north into our southern California waters. The cooler water stimulates the kelp forests in a cycle of regrowth at a rate of up to two feet per day.

The pelagic fish that have gathered in the summer and fall months have headed south in search of warmer Baja waters. The Channel Islands settle into a winter routine with kelp bass, giant black sea bass, schooling barracuda and other perennial species remaining.

Pelagic birding in the inshore waters between California's coast and these islands along with the "deep blue sea" offshore areas past the edge of the Continental Shelf abound with nomadic seasonal bird species. Albatross, shearwaters, terns, gulls, tropicbirds, kittiwakes, jaegers, boobies and petrals are just a few species encountered.

Marine mammals abound in the waters around the Channel Islands during the winter months. The once endangered California Gray whale passes close by enroute north and south on its 12,000 mile migration. Seals, sea lions and elephant seals also cruise the waters and haul out on the shores of these islands.

Spring's arrival warms the water and the hearts of the ocean's inhabitants. Seals and sea lions give birth to pups, sea bass and bat rays display dramatic mating rituals and garibaldi fish guard their nests. Massive schools of sardines and mackerel form huge biomasses and are a prelude to summer.

The waters warm and soon summer is here. Pelagic fishes such as yellowtail, yellowfin tuna and bluefin tuna are attracted to the islands by the endless food supply. Blue whales migrate through our waters and pods of common dolphins stretching as far as the eye can see often surround the boat.

Before you know it fall is here with some of the clearest and calmest water of the year. Water temperatures in the mid to upper 60s are delightful when combined with water clarity so great one gains the unreal sensation of flight.

The seasons change and the cycle continues as it has for thousands of years. Our goal is to observe these changes while not disturbing nature's beauty. Whichever season you choose, each offers a unique and exciting experience with nature.

Local San Diego Dive Sites

Coronado Island

The Coronados offer divers a remote untamed Baja experience just 16 miles due south of our harbor. Located in Mexican waters, this group consists of three main islands and a smaller islet. They have gone by many names throughout their colorful history since Juan Cabrillo passed them on his way to San Diego in 1542. Today they bear the likely names of North Island, South Island, Middle Island, and Middle Rock.

North Coronado Island:
Lying just to the east of a deepwater canyon, North Island offers the greatest range in surrounding depths for a wide variety of diving profiles. Composed of steep volcanic rock that rises abruptly from the sea, the island is host to a fairly large colony of sea lions.

The island's submerged topography is a jumble of boulders and jointed reef structures that tumble precipitously to sand or cobbles starting at depths from 50 to 140 feet. The usually protected lee side is a favorite first dive that frequently hosts visibility of 60 feet or better. The rugged windward side is an added treat on those rare days when it is calm enough to dive. Patches of purple hydrocorals adorn barren rock reefs at depths of 80 feet or more.

In shallower water, members of the resident sea lion colony entertain with their antics.

Middle Grounds:
The name collectively refers to Middle Coronado Island and the smaller adjacent Middle Rock. Several species of sea birds nest and raise young here. A small harbor seal population supports itself here.

Diving depths are moderate until one moves to the west of either landmark. Shallower depths sport rocky ledges adorned with false eel grass. A little deeper, wildly uplifted bands of rock form deep ledges that provide homes for a wide variety of creatures.

South Island:
Largest of the Los Coronados group, South Island is the site of the only human habitation on the islands. The Republic of Mexico maintains a small naval garrison above a cove on the lee side that once boasted a casino. Fire and the elements have reclaimed the remnants of that by-gone era.

Northern elephant seals and California sea lions share a cove on the windward side that is ringed by high unstable cliffs. To the east, several offshore reefs host the richest invertebrate habitat south of the Northern Channel Islands.

 

Wreck Alley

Multiple wrecks and structures make up wreck alley:

  • HMCS Yukon - 366' Canadian destoyer escort sunk in 2000 lying in 105 feet of water. The average depth along her starboard side is 70 feet. She is slowly becoming covered with a vast array of invertebrate life including - Metridium anemones and corynactis anemones
  • Ruby E - 165' retired United States Coast Guard cutter sunk in 1987. She lies in 85 feet of water and is covered with life!
  • El Rey - 110 ' ex kelp harvester (Lawnmower of the kelp forest) sunk in 1987. She lies in 75 feet of water and is completely covered with invertebrate life.
  • NOSC Tower - Former research tower knocked over during an El Nino storm in 1988. Lying in 65 feet of water is covered with invertebrate life and good for novice divers due to it's depth.
We offer 2 and 3 tank trips to Wreck Alley in conjunction with dives to the Point Loma Kelp Forest. We require a minimum of 10 cold water dives prior to diving in Wreck Alley due to depth, sometimes poor visibility, current and swell.
 

Point Loma Kelp Forest

Just outside of our harbor in San Diego lies some of the most beautiful kelp forest diving you will find along the California coast! The lay of the land encourages nutrient rich upwellings from the deep offshore waters adjacent to San Diego, hence the vast forest of kelp that thrives in the cooler waters that frequent our coastal area.

Beginners to seasoned dive veterans will enjoy our site selection that will not be so destination oriented as you may see from local San Diego day boats. We will visit the sites for the day that offer the best conditions in a similar manner to our Channel Island live aboard adventures. We want to ensure that you have the opportunity to get in the best dives for your money, not a particular dive site that may or may not be good on the particular day you decide to go diving.

You will find depths varying from 30 to 105 feet, with considerations made for all levels of experience. Some of the locations you may have the opportunity to explore:

  • NRAD Reef
  • Langosta Ledge
  • Ancient Sea Cliffs
  • Train Wheels
  • Wreck of the Lazy Days
  • 7 Fathom Pinnacles
  • New Hope Rock

You can experience the amazing Point Loma Kelp Forest on a stand alone 2-tank departure or on a longer 3-tank Wreck Alley / Point Loma Kelp or 4-Tank Coronado Islands / Point Loma Kelp itinerary.

 

Channel Island Dive Sites

Tanner Bank

The Tanner Bank, located 105 miles west of San Diego and 35 miles west southwest of San Clemente Island, is an undersea mountain ridge or seamount that rises to within 80 feet of the surface.

The Tanner Bank is a truly wild spot best dived by advanced divers. It is a far cry from the Caribbean! The Bank is far from land and is often swept by strong open ocean currents and large swells -- considerable surge can be encountered even at depths approaching 100 feet!

Then why dive the Tanner Bank? Because you'll be diving a wild and stunningly beautifully open ocean seamount that acts as a giant sealife magnet!

Vertebrates and invertebrates call the Bank home. Since the seamount is a truly an open place, sightings of pelagic animals are common. Tuna, huge numbers of yellowtail (jack family), large schools of baitfish, large rafts of sea lions and occasional sharks are seen here.

The water is typically very clear here with visibility approaching 100 feet due to the open ocean currents that sweep the Bank. Giant kelp does not grow here, but endless swaying carpets of short, tough palm kelp cover most of the seamount. Below the kelp are found crevices and cracks, loaded with bottom fish, huge tufts of purple hydrocoral.

Diving at the Tanner Bank can be exciting, challenging and beautiful! Diving is deep with the shallowest site at 80 feet and most are in excess of 90 feet. Make sure that you are thoroughly familiar with your dive gauges and computers, and that you are comfortable with these depths.

Since no islands exist at the Tanner Bank to offer protection from wind and swell, the boat may roll while at anchor. The crew is expert at conducting dive operations in these conditions and will help you on and off with your tank and with your entry into and exit from the water. On multiple day trips more than one day could be spent on the Bank. But if weather conditions are not favorable we'll take you to either San Clemente Island or San Nicholas Island.

If you are comfortable with open ocean diving conditions, the Tanner Bank should be high on your diving priority list. Perhaps nowhere else while diving in California will you feel so "out there". Tanner Bank is a remote, exciting and pristine dive spot that is abundant in both game and scenic beauty!

 

San Nicholas Island

San Nicholas, a.k.a. San Nick, is the most northwesterly of the four southern Channel Islands. Like its eastern neighbour, San Clemente Island, San Nick is a U.S. Navy owned and operated island. The waters surrounding the island are split into three zones that are controlled by the Navy. Most of our diving is done on the north and west sides of the island while the eastern side is generally off limits. The cool thing for us/you is that the sides that are generally accessible are outta sight and dynamite!!!!

Kelp city! Thick forests of giant kelp surround the entire island. Generally, where there is kelp, there is tons of life! But to to find the life you must start at the bottom. The bottom of the food chain that is! The water at San Nick is generally cooler than the other southern channel islands, due in part to its more northerly location. Plankton, the first step in the oceans food chain, thrives in the cool water. If the plankton are happy, then the rest of the food chain is happy! Marine mammals, fishes and invertebrates thrive in San Nick's nutrient rich environment. A diverse mixture of northern cold-water fish (Lingcod, China rockfish, olive rockfish, etc.), and southern warmer-water fish (yellowtail-jack family, bonito, etc.) intermingle in the island waters. Invertebrates ( sea fans, anemones, sea stars, abalone-fully protected, sponges, lobster, etc.) take full advantage of food supply. Playful sea lions, timid harbor seals and massive elephant seals are abundant at San Nick. They use the island to raise their young and to rest between hunting excursions into the ocean.

If photography is the objective of the trip, and the ocean is calm, we could venture offshore to the majestic spire Begg Rock. This awe inspiring pinnacle rises 300 feet from the ocean floor to the surface and is carpeted with invertebrate life! We target San Nicholas Island only on multiple day live-aboard trips. Due to the nature of the diving, this destination is recommended for divers with experience in kelp and adverse diving conditions.

If you're looking for an island where the cool north meets the warmer south. An island where all forms of life thrive in an extremely nutrient rich environment, then San Nicholas Island is for you!

 

Santa Barbara Island

Also known as 'The Island of the Sea Lion', also offers clear water and incredible invertebrate life. Though small in stature, Santa Barbara boasts a large rookery of California sea lions that provide hours of endless interaction!

Young pups sun themselves on the surface while adults speed through dense kelp beds and over the rocky reefs below. Keep your eyes open and watch your back -- harbor seals also live here and seem to enjoy sneaking up to scare the heck out of you while diving and snorkeling. Angel sharks and bat rays are easily found throughout the island's scattered sand flats.

Kayaking Santa Barbara is an experience as the sea lions enjoy frolicking in close proximity and you'll quite often find dozens of pups peering at you from all sides!

Divers, if you enjoy dramatic terrain and depth you will want to dive the outside of Sutil Island, Black Caverns and the Underwater Arch. In season, lobster diving can be excellent. While white seabass and yellowtail prowl the outer edges of the kelp forests in search of a baitfish meal.

Plus the underwater spectacle of thousands of brittlestars, arms outstretched for a detritus meal...it is hard to fathom the sheer numbers of brittlestars that carpet the bottom of many of the dive sites!

Santa Barbara Island is part of the Channel Islands National Marine Sanctuary with 1/3 of it's aquatic area designated a reserve, off limits for hunting.

Beginner to advanced divers will enjoy all that Santa Barbara Island offers. You will find that we visit here on 2 - 4 day dive and eco adventures.

Santa Barbara Island, "The Island of the Sea Lion"!

 

 

Cortez Bank

The Cortes Bank is located 100 miles west of San Diego and 40 miles southwest of San Clemente Island. It is a undersea mountain ridge or seamount that rises to within 20 feet of the surface in many places.

The Cortes Bank is a truly wild spot best dived by intermediate to advanced divers. It is a far cry from the Caribbean! The Bank is far from land and is often swept by strong open ocean currents and large swells -- considerable surge can be encountered even at depths approaching 100 feet!

Then why dive the Cortes Bank? Because you'll be diving a wild and stunningly beautifully open ocean seamount that acts as a giant sealife magnet! Vertebrates and invertebrates call the Bank home. Lobster in great numbers can be found here for those who know where to look! In fact many of our dive trips to the Cortes Bank are scheduled during lobster season (October - March).

Since the seamount is a truly an open place, sightings of pelagic animals are common. Tuna, huge numbers of yellowtail (jack family), large schools of baitfish, large rafts of sea lions and occasional sharks are seen here.

The water is typically very clear here with visibility approaching 100 feet due to the open ocean currents that sweep the Bank. Not much giant kelp grows here, but endless swaying carpets of short, tough palm kelp cover most of the seamount. Below the kelp are found crevices and cracks, loaded with bottom fish, lobsters, moray-eels, abalone and huge tufts of purple hydrocoral.

Diving at the Cortes Bank can be exciting, challenging and beautiful! Although the captain anchors in progressively shallower spots as the day goes on, the first dive each day is typically in excess of 60 feet.

Since no islands exist at the Cortes Bank to offer protection from wind and swell, the boat may roll while at anchor. The crew is expert at conducting dive operations in these conditions and will help you on and off with your tank and with your entry into and exit from the water. On multiple day trips more than one day could be spent on the Bank. But if weather conditions are not favorable we'll take you to either San Clemente Island or San Nicholas Island.

If you are comfortable with open ocean diving conditions, the Cortes Bank should be high on your diving priority list. Perhaps nowhere else while diving in California will you feel so "out there".

Cortes Bank is a remote, exciting and pristine dive spot that embodies the spirit of adventure!

 

Farnsworth Bank

So you'd like to dive an open ocean style seamount, but would like to have the option of a fantastic island dive! FARNSWORTH BANK located just one and one half miles off of the windward side of Catalina Island is your destination.

This seamount attracts a variety of pelagic fishes and mammals as well as being home to a myriad of reef fishes and invertebrates. Huge tufts of purple hydrocoral cover the mount from 65 to over 100 feet in depth, while nudibranchs and sedentary bottom fishes hide amongst its stalks.

Imagine peering down a crevice at a moray eel when all of a sudden you sense that the sun has set. Looking toward the surface you realize that the sun hasn't set, but has been blocked out by the largest school of mackerel you've ever witnessed! The mackerel vanish. What's next? Barracuda! California barracuda by the hundreds, harmless to you, in search of lunch.

You meander your way across the bottom, coming face to face with a torpedo ray and just before you find your way back to the anchor line to start your ascent, you peer over the edge of a sheer 75-foot wall!

This dive can be fairly demanding due to open ocean conditions, intermediate to deep water (60-130 feet) and current. You should have upper intermediate to advanced level diving skills.

FARNSWORTH BANK, open ocean thrills, close to shore!

 

Catalina Island

"Catalina." Just uttering the name of this enchanted island brings visions of romance and excitement. But for divers, it holds that and so much more! Catalina, 22 miles in length, is the 3rd largest of the 8 channel islands. This island, lying 20 miles off the California coast and just 67 miles northwest of San Diego, offers the rare combination of beauty above and below water!

Catalina, deep in history, was first occupied by American Indians. Numerous archaeological sites have revealed more than 6000 years of Indian history on the island. The first European influence arrived in 1542 when the Spaniard Juan Rodriguez Cabrillo discovered and named the island, San Salvador. Then 60 years later, Viscaino rediscovered the island and named it Santa Catalina. In the 1700's, Aleut Indians hunted sea otters for their fur in the waters
surrounding the island. Then in 1848, at the end of the Mexican American War, Catalina became American territory.

Enough about the past, lets talk about the present! Now, in more ways than one, Catalina is known as a world class destination. Camping, mountain biking, hiking, shopping in world-famous Avalon and diving are just a few of the activities you can enjoy on and around the island!

Did someone mention DIVING?! Hey, the diving at Catalina is first class. Beginners to experienced will get a rush out of the islands diverse underwater terrain! Abrupt walls, spectacular pinnacles, towering kelp forests and a nearby purple hydrocoral encrusted seamount keep everyone interested. The marine life around Catalina can be as good as any of the Channel Islands. Kelp bass, giant black seabass (up to 500 lbs.), yellowtail, barracuda, garibaldi, sea stars, occasional seals and sea lions... You get the picture!? If you name it, you can generally find it!

Another Catalina feature is easy snorkelling. If you aren't SCUBA certified, or you would like to bring along someone that isn't, this island has perfect areas for beautiful, relaxing snorkeling. The islands shallow coves with bat ray inhabited sand flats and shallow rocky reefs are absolutely vibrant with life! Catalina is a great place for beginning to experienced divers and Snorkelers. To take advantage of all that Catalina has to offer, we visit this destination ONLY on our multi-day liveaboard trips.

If you're looking for a destination to explore above and below, join us on a trip to beautiful Catalina!

 

San Clemente Island

Located just 60 miles west of San Diego, this 18 mile long island is the jewel of the southern Channel Islands!

Sunlit shallows and vertical walls of San Clemente's leeward side are an excellent place for beginners to acclimate themselves and for more adventurous to explore walls and deep pinnacles.

The world-famous Pyramid Cove is an absolute diver's Mecca. The cove, which encompasses four miles of the southern end of San Clemente, has dozens of dive locations with extremely diverse underwater terrain. The canyons , arches, walls, and redwood-like kelp forests have earned this area the distinction of being rated among the best dive destinations in the world! You could spend a week here and not hit all of the amazing dive sites.

For the adventurous, San Clemente's windswept backside is the place to observe nature as it was. Due to the prevailing wind and the open-ocean sell, we rarely get to dive this area. But when Mother Nature allows us to venture up the windward-side we feel blessed. Pristine kelp forests, abrupt walls, huge fish, crevices packed with spiny lobster...absolutely more life than can be viewed in one dive, or one trip for that matter.

San Clemente's far west end offers more magic. The Coral Garden and Purple Boilers, carpeted with beautiful purple hydrocoral, are a photographer's dream. Castle Rock's shallow water caves and kelp forest offer unparalleled exploration possibilities. Northwest Harbor, with its calm water and small sea lion rookery is the place to come face-to-face with a sea lion.

San Clemente offers something for everyone. Beginners to advanced divers will enjoy the same dive sites. Photographically speaking, YOU WANT TO VISIT SAN CLEMENTE ISLAND!

Don't miss out on the jewel...San Clemente Island!
