Quick Answer: 5 Best Snorkeling Spots in San Diego

1. La Jolla Cove


This is one of the largest snorkeling spots in the world has over 6 000 acres of fun to be explored. It is made of the La Jolla Underwater Park and Ecological Reserve. You can also do more than snorkel here. Depending on the time of year you can also surf and even walk along the boardwalk. This area also has great bars and restaurants close by.

It is best to check the weather conditions before heading to this area as they can change drastically from day today. You can expect to see a stunning kelp forest and deep canyons along the bottom with great visibility.  Be sure to have a quality full face mask as you will not want to miss these sights. The first 30 feet or so will be sand and grass but after that is where the fun begins.

There are sea creatures here that you have probably never heard of including sheep crab, sea lions, and even lobster. If you are lucky you may even see some stingrays swimming with you.

2. Devil’s Slide + Sea Lion Caves


This is one of the best places to snorkel in San Diego. It is not easy to get to but well worth the effort. Be sure to bring along your fins to this place as it can be a long swim. For this reason, this area should be reserved for at least intermediate swimmers. There is no beach or easy entry or exit at this location and even requires a little hike to get to the water.

The waters are around 15 to 20 feet when you’re swimming 25 feet from the shore. You shouldn’t expect a sand beach here as the shore is made up of large rocks. What makes this a great swim in the rock formations along the shore. Water has eaten away at the rock and formed caves that you can swim through. This is best done at low tide so you can see the full caves and tunnels. Just be sure to be cognizant of the tide and current. These caves can cause some weird currents that can make swimming difficult.

Remember: Do not touch or pick up any of the sea life on your snorkeling trip. Blowing bubbles is also seen as a form of aggression to sea lions so be sure to breathe through your snorkel at all times when they are around.

Many animals call this area home including loads of sea lions, rays, and even leopard and horn sharks. Don’t be surprised or alarmed when a sea lion or five start swimming with you through the water. The water here is clear and blue. We recommend going with a quality mask and dry snorkel as you will surely be tempted to free dive below the surface. You don’t need white sand to have an amazing time in the water.

3. Shell Beach + Boomers Beach

Shell Beach

This is a short drive sound from the famous La Jolla Cove. Shell and Boomer’s beach are both less busy and have a similar stellar snorkeling route. You will be happy to know these places have picnic areas with grass to play on and bathrooms and showers to change at. Their parking lots are on the smaller side so get here early in the day. If you are looking to escape the crowds of other beaches in the area Shell and Boomer’s beach is where you want to be.

These beaches are also great for other activities as well. You can bodysurf, scuba dive and even whale watch here. Since this area has a rocky bottom and shore it is for advanced snorkelers. There is a strong current in some parts and knowing how to get out of it is key. Be sure to wear a life vest when snorkeling in this section to secure your safety.

4. Mission Bay


This is one of the treasures of the west coast. This snorkeling spot is excellent for the main fact that it is largely unknown and beautifully untouched and is still pristine. Located at the south end of Mission Boulevard this bay is quite desirable as the water is calm with only a little surf. Great for beginners and families alike, you are bound to enjoy the shallow waters and lack of current.

While the waters may be calm, the world under it is full of life. With lots of colorful coral, rich grasses, and plenty of swarming fish, you will want to have your underwater camera closely on hand. There is a rock jetty that stretches along the ocean’s floor. Coming up to shallow waters, there are some points where the water is a mere 2 feet deep. This allows you to get an excellent close up of all the colorful corals.

The reef features colorful reds, pinks, and oranges that brighten up all the life underwater. When exploring here be sure to keep your eye out for sea cucumbers, spiny lobsters, and even octopuses.
