Channel Islands SCUBA Diving, California: GIANT KELP DIVING

I had descended without any issues and was now about 30 feet/ 9 meters underwater.  In front of me was a wall of giant kelp.  Golden seaweed stretched from the seafloor a couple of meters below me way up to the surface far above me.  I slowly swam into the kelp, gently pushing the swaying vertical fronds apart.  I was soon lost in a forest of seaweed, with just my dive buddy beside me.

A bright orange fish swam past.  I was distracted by the flash of color, when suddenly something bigger and darker dashed up to me.  Right on front of my nose, looking into my mask, was a playful harbor seal.  It looked at me, then turned and darted away, almost immediately disappearing into the kelp.  How cool was this?!

I was at the Californian Channel Islands, SCUBA diving near Anacapa Island.

THE INSPIRATION: Channel Islands SCUBA diving, California

The United States has some incredible diving, including diving with manta rays in Hawaii.  It strange to think of L.A. and diving together, but actually kelp diving in California is one of the top dive experiences in the world.  I had wanted to go on a SCUBA diving trip in California ever since I’d first read about the giant kelp forests, so when we planned a trip to southern California, it was on my list of things to do.

Getting to Anacapa Island

Anacapa Island actually consists of three smaller islets, East, Middle, and West Anacapa Islands. They are located approximately 14 miles/ 22.5 km south of Ventura, California and boats usually leave from Ventura Harbor.  The boat left at 7:30 am and we were staying in central L.A., so we had headed out at 5:30 am to make sure I was there in time.  Kevin is not a diver, so he drove me there – and then spent the day hanging out in L.A. before picking me again when we got back about 6:00 pm.

The Anacapa Islands are beautiful – jutting straight out of the ocean, and I was excited as we approached them.  They are actually the closest of the eight Channel Islands to shore (when reached from Ventura Harbor) and it only took about 1.25 hours to get there.

Channel Islands Diving

Dive 1: Canyons

This was a nice introduction to the kelp forests.  Maximum depth 39 feet/ 11.8 m.  We jumped in just outside a small kelp forest and swam into the kelp.  It was awesome!  It’s another world, being surrounded by giant seaweed fronds, pushing them apart to make my way through them. There wasn’t much marine life other than the kelp, but I was in heaven.

Dive 2: Cathedral Cove

This was the best of the three dives of the day.  Maximum depth 38 feet/ 11.5 m.  There was lots of kelp and bright garibaldi fish that this area is well known.  They are really cool.  There was also plenty of other fish swimming around.  There was no shortage of things to look at and enjoy.  And of course, my encounter with a harbor seal (or was it a sea lion? – I’m actually not sure).  It darted away quickly, but came right up to my mask and looked at me.  Great fun!

Dive 3: Winfield Scott

Another great dive to end the day.  Maximum depth 36 feet/ 11 m.  More kelp of course (which was the main thing I wanted to experience), but there were lots of other cool things like giant lobsters and sea cucumbers.

Of course there was lunch in between and a weary but extremely satisfied James on the way back.

The verdict: Kelp forest California diving

It was everything I had imagined!  Diving through the California kelp forests was incredible.  The cheeky seal (sea lion?) was an added bonus!

The Experience: Kelp diving, California

Diving in the giant kelp forests of California is one the world’s top diving experiences.  The giant seaweed forests are around the Channel Islands.

The Channel Islands and Channel Islands National Park

The Channel Islands are eight islands off the coast of California around L.A.  The five northern Channel Islands (San Miguel, Santa Rosa, Santa Cruz, Anacapa, and Santa Barbara Islands) make up the Channel Islands National Park.  The other three (the southern Channel Islands) are Santa Catalina, San Clemente and San Nicolas Islands.  Seven of the islands are nature reserves.  Santa Catalina (usually just called Catalina Island) is the only one of the eight islands with human settlements.  There are two towns – Avalon and Two Harbors.

The Channel Islands’ kelp forests are the area’s main attraction. Probably the two most famous islands are Catalina Island and Anacapa Island.

Where is best to dive the Channel Islands?

There are a few options to SCUBA the Channel Islands.  The main options (including how to get to the Channel Islands) are:

1. Diving straight from Santa Catalina Island

Catalina Island SCUBA diving can be done from the island or from the mainland.

Getting to Catalina Island

There are two towns on the island and both have ferries – Avalon and Two Harbors. Ferries leave from 3 different ports, all south of LA. Click here for the schedule of the Catalina Express ferry to/ from Catalina Island.

Catalina SCUBA diving is possible from both towns.

Dives from Avalon, Catalina

In Avalon, there is shore diving from Casino Point at Casino Point Underwater Park/ Avalon Dive Park.  One of the main Catalina Island diving operators in Avalon is  Catalina Divers Supply.  They have shore dives and boat dives. Shore dives are at the Avalon Dive Park daily at 8:00am, 10:00am, 12:00pm, and 2:00pm (2 hours each dive) The price of $115 per person or $135 for a private experience includes all equipment.  Their boat dives are Fridays, Saturdays & Sundays 9:00 a.m. to 2:00 p.m.  Prices for boat dives from Catalina is $107 for 2 dives (gear NOT included) and $85 for snorkelers (includes gear).

Dives from Two Harbors, Catalina

You can rent dive gear at Two Harbors and do shore diving by yourself (with a buddy, of course).

Other things to do on Catalina Island

There are actually lots of fun things to do on Catalina in addition to diving, including a zip line, a food tour and a bison tour. Check out all of the fun Catalina expediences here.

2. Diving Catalina Island as a day trip from LA

Boats for the Catalina Island kelp forest usually leave from San Pedro port south of LA.

There are several operators.  Eco Dive Center has Catalina Island Diving trips go most weekends from San Pedro.  It costs $135 for 3 dives (gear not included).  You can check out their trip schedule here.

You can also take an underwater photography course at Catalina Island: book here.

3. Diving Anacapa Islands and/ or Santa Cruz Island

Boats for Anacapa Island SCUBA diving and Santa Cruz usually leave from Ventura Harbor north of LA.

Eco Dive Center also has Anacapa SCUBA diving trips (often alternating weekends with their Catalina trips) from Ventura Harbor.  It costs $140 for 3 dives (gear not included, but can be rented at their dive shop) for Anacapa and/ or Santa Cruz.  You can check out their trip schedule here.  This is the trip I did and I was extremely happy with their service.

Blue Holic SCUBA also has a monthly trip to Anacapa/ Santa Cruz, also leaving from Ventura Harbor.  Prices were not available on their website.

4. Diving San Miguel Island and/or Santa Rosa Island

The boats for the most northern Channel Islands usually leave from Santa Barbara.

Blue Holic SCUBA also has one or two trips/ month to San Miguel / Santa Rosa Island.  The 3-dive trip leaves at 3:00am from Santa Barbara.  You need to board before midnight and sleep onboard.  Prices were not available on their website.

The best choice for Channel Islands diving

Of course, the best choice is different for everyone.  However, for me, Eco Dive Center was the best for several reasons.  I did this dive as part of a bigger trip around California, and this dive was a day trip, not the main focus of the vacation.  And my husband doesn’t dive, so I wanted to limit this to one day.

  • They have a shop in Culver City. I needed to rent some of my equipment, so had to go there the day before the dive.  The fact that their dive shop was central, rather than out by the port, made this more convenient.
  • I could do it one day. The trips from Santa Barbra and from Catalina Island take up more than a day.
  • I did the trip to Anacapa rather than Catalina only because this was the trip running on the day I had available. I think either of them would be equally great.

Eco Dive Center was well organized and the equipment I rented was in good working condition.

If you specially want to go SCUBA diving in Channel Islands National Park, then options 3 and 4 are for you, because Catalina is outside the national park.  However, diving Channel Islands National Park isn’t necessarily any better – the California giant kelp forest extends throughout all of the Channel Islands and is common all around Catalina.

If you are not a diver, but still want to experience the California kelp forest, then Channel Islands snorkeling is also an option.  Most dive centers also have prices (and equipment) for snorkelers.

Best time of year for Channel Islands SCUBA diving

So, when is the best time to dive the Channel Islands?

Visibility of Channel Islands for diving

Channel Islands diving (and snorkeling) is possible all year round.  However, the best underwater visibility in the Channel Islands is between July and January and sometimes into February. The best visibility is September to November.  I dived in November and visibility was good.  The southern Channel Islands have the clearest water, with visibility up to 80 feet (24 meters) of visibility.  April to June there are often plankton blooms and green water, with visibility of about 20 feet/ 6 meters.

Channel Islands water temperature

Summer is obviously the warmest and from mid-July to late October, the surface water temperature is over 70°F / 21°C.  The Channel Islands are coldest between February and late June (around 50°F / 10°C).  The southern Channel Islands Catalina and San Clemente are warmest, and San Miguel up north can be below 50°F / 10°C.

Other things to do in Los Angeles

Two other fun things to do in the Channel Islands are:

 

I did the Channel Islands kelp diving as a day trip as part of a bigger vacation to Los Angeles.  There are a lot of awesome experiences you can have in Los Angeles other than diving.  These will really make your vacation a unique travel experience.

 

Where are the Channel Islands and what is the currency?

The Channel Islands are off the coast of California, USA, near Los Angeles.  The currency is the U.S. dollar (USD)

Visa requirements for Los Angeles

Check out visa requirements for the United States here.

Getting to Los Angeles

Los Angeles’ airport is LAX. Book a flight to LAX here.

Getting to/ from Los Angeles LAX Airport

If you don’t rent a car, the easiest way to get from LAX Airport to the center of Los Angeles is a shuttle.  Book a shuttle here.

Getting around Los Angeles and to the Channel Islands

Los Angeles is a driving city.  Public transportation is terrible and things are spread out.  It is almost impossible to get around without a car.  Even more to the point, the ports where the dive boats or ferries leave from are not accessible by public transportation and you need to get there early.  Rent a car here.

Drive times from Hollywood to the ports:

  • Hollywood – San Pedro: 40 minutes
  • Hollywood- Long Beach: 40 minutes
  • Hollywood – Dana Point: 1 hour 20 minutes
  • Hollywood – Ventura Harbor: 1 hour 10 minutes
  • Hollywood – Santa Barbara: 1 hour 50 minutes

NOTE: These times are approximate and are for early morning, so traffic is light.  Traffic in LA is notorious for being terrible, so factor in additional time just in case.

Map of the Channel Islands

I had no idea where the ports were and where they were in relation to downtown LA, and to the different Channel Islands when I first started planning my trip.  It is really helpful to know this though, when deciding what option to choose.  So, I made this map:

Channel Islands Map

Where to stay in Los Angeles

I use booking.com because they have a great selection and good prices.  Check the latest prices on Los Angeles’ accommodations here.

Not sure what to choose? Check my Guide to Choosing the Perfect Hotel for tips.

Two great choices of places to stay in L.A. are:

Selby Ave Guest House

Selby Ave Guest House has a perfect rating of 10 on Booking.com!  It’s a one-bedroom cottage with a patio and pool.  You can cook if you want to save money.  There is free parking – important since you will most likely have a car to get around.  It’s in Westwood (where Kevin grew up ?) – it’s a nice area and centrally located. 

46776267

Book Selby Ave Guesthouse here.


Garden Cottage B&B

A cheaper option is Garden Cottage B&B.  It has a great central location, a nice garden, breakfast and free parking.  It has a high rating on Booking.com. 

239393751

Book the Garden Cottage B&B here.


If your main focus is diving and you want to stay near the harbor, then two options are:

San Pedro/ Long Beach

Crowne Plaza Hotel Los Angeles Harbor.  It’s functional and bland, but close to the harbor, so a very convenient departure point for early morning boat trips or ferries. 

9fb4ab21524b3e5de19c6c6712f6ebc6

Book the Crowne Plaza in San Pedro here.


Ventura Harbor area

A cheap motel option not far from the boats is the Crystal Lodge Motel in Ventura.

Book the Crystal Lodge Motel here.


Planning and packing for diving at the Channel Islands off the coast off L.A.

I use the Internet a lot to plan – and I hope this blog is useful resource for you – but I also always use a guidebook as a supplement.  Buy the Los Angeles/ southern California Lonely Planet here. If you are traveling to the US from abroad, I recommend my North America Travel Guide for lots of extra information and practical tips.

When you’re ready to start planning your trip, take the stress out of it by referring to my Travel Planner for a step-by-step guide.

When you are ready for your trip, check out my Essential Packing List.

Dive gear for diving the Channel Islands

I like to travel light without a whole bag of dive gear, because this was just on part of a bigger trip.  The basic essentials for this trip are:

1. Mask

It’s possible to rent mask and fins, but they typically suck, so I try to bring my own with me if at all possible. I love the Aqualung Mask.  It fits great – I have a high bridge over my nose and used to get headaches from ill-fitting masks.  The Aqualung Mask did away with this, so I LOVE it.  If you are looking for a new mask, buy the Aqualung Mask here.

2. Fins

I prefer open-heeled fins, as they are easier to get on and off.  The booties that you have to wear also keep your feet warm.  I like Tusa Imprex fins.  If you are looking for new fins, buy the Tusa Imprex fins here.

3. Booties

You need booties in cold water, of course, and 5mm is best at these temperatures.  I was very comfortable with my Scubapro booties.  Buy the Scuba Pro (unisex, 5mm) booties here.

4. Knife

I actually got a knife specifically for this dive.  Of course, it’s always a good idea to take a knife with you, but it is essential when diving in kelp because it is possible for the kelp to get caught around your tank and/ or BCD.  You should NEVER dive in kelp without you and your buddy having a knife. Buy the Tusa Imprex knife here.

5. Dive Flashlight

I first got a dive flashlight when I started doing night dives, but now I always carry it with me.  There will often be a crevice or hole to explore.  I actually take my dive flashlight with when I travel even when I’m not planning on diving – you never now when a waterproof flashlight will come in handy. I’ve used it for hiking, camping, and caving. I like the BigBlue dive torch – it’s small but fairly powerful.  Buy the BigBlue dive flashlight here.

I rented wetsuit, hood, gloves, BCD and dive computer from the dive shop, but of course, if you have gear and want to bring it, your own gear is always most comfortable.

Additional consideration: Travel Insurance

My aim is to not only inspire you to have amazing experiences when you travel, but to also give you the practical information and resources you need to have them.  In addition to accommodation, planning and flights, you should always have travel insurance, just in case.  A great insurance option is World Nomads.  You can book it here or get a quote for your trip right here:
