Kelp forest, garibaldi, and summer leopard sharks — mostly within a half mile of La Jolla.
Last updated
Almost all good snorkeling in San Diego happens inside the La Jolla Ecological Reserve, a no-take marine protected area that has been closed to fishing for decades, so fish are abundant and unbothered. La Jolla Cove is the classic entry: a small protected beach with kelp, garibaldi (California's state fish), bat rays, and sea lions. La Jolla Shores near the Marine Room is the calmer, sandier option and the summer home of hundreds of harmless leopard sharks, which gather in the warm shallows roughly July through October. Shell Beach and the Children's Pool area work when the Cove is crowded. Best conditions are late summer and fall, when water hits the upper 60s to low 70s and visibility can reach 20-30 feet; winter drops to the mid-50s with murkier water after storms. A 3/2 wetsuit is comfortable most of the year and effectively required November through May. Go early, before wind and crowds.
| Spot | Best for | Notes |
|---|---|---|
| La Jolla Cove | Kelp, garibaldi, sea lions | Small beach, crowded by 10am |
| La Jolla Shores / Marine Room | Leopard sharks, easy sandy entry | Best July-Oct |
| Shell Beach | Quieter, tide pools nearby | Rocky entry, check swell |
| Point Loma tide zones | Tide pool life | Slippery, low tide only |
| Water temp | Mid-50s winter, upper 60s-low 70s late summer | 3/2 wetsuit most of the year |
The postcard spot. A tiny cove with rock walls, kelp just offshore, and thick fish life thanks to the reserve. Sea lions haul out on the surrounding rocks and will swim past you — give them space and never get between an animal and the water.
A long sandy beach with the easiest entry in the county. Swim toward the Marine Room in late summer and you'll find the leopard shark aggregation in waist-to-chest-deep water. They have tiny mouths and no interest in people.
Just south of the Cove, smaller and usually less crowded, with tide pools at the north end. The rocky entry requires reef booties and a calm day.
Better for tide pooling than swimming, but a low-tide morning here shows anemones, urchins, octopus, and small fish without getting fully in.
Operators at La Jolla Shores run guided snorkel and snorkel-plus-kayak combos, typically $50-$90 with gear and wetsuit included. Worth it for a first time or for kids.
August through October is the sweet spot: warmest water, calmest surf, best visibility, and peak leopard shark season. Spring is cold and often murky from plankton blooms.
Ranges from three feet after a storm to 30 feet on a good fall morning. Swell and rain runoff are the two things that ruin it — avoid the 72 hours after heavy rain.
Rent a 3/2 wetsuit and fins near the Cove for around $20-$35 a day. Mask fit matters more than anything else; test the seal before you're in the water.
Nothing may be taken from the La Jolla Ecological Reserve — no shells, no lobster, no fish. Touching or chasing marine mammals is a federal violation.
Snorkel with a buddy, wear a bright cap or float so boaters see you, and stay inside the marked swim area. Rip currents at the Shores pull toward the boat lane.
La Jolla Cove for kelp and fish, and La Jolla Shores near the Marine Room for easy entry and summer leopard sharks. Both sit inside the protected La Jolla Ecological Reserve.
Roughly July through October, when hundreds gather in the warm shallows off La Jolla Shores. They're harmless and can be seen in chest-deep water.
In late summer many people snorkel without one. From November through May, water in the mid-to-high 50s makes a 3/2 wetsuit close to essential.
Usually 10-20 feet, up to 30 on a good fall day, and as little as three feet after a storm or during a plankton bloom.
Yes on a calm day, though the Cove's small beach and occasional surge can be intimidating. Beginners often have an easier first time at La Jolla Shores.
