The best shore dives in San Diego, and who each one suits

San Diego's shore diving is concentrated in one small stretch of La Jolla, and that's good news: within a mile you get a beginner-friendly sand slope, a submarine canyon that drops past 900 feet, and a kelp-and-reef cove full of bright orange garibaldi. All of it is protected. Here's where to enter, how deep each site goes and who it actually suits.

La Jolla Shores and the canyon

This is where most San Diego scuba classes happen, and for good reason. You walk in off the sand at Kellogg Park, and the bottom slopes gently to about 30 feet over several hundred yards before steepening into La Jolla Canyon at around 60 feet. Divebums' site guide describes routes to the north wall (about 70 feet) and the gorgonian-covered Secret Garden at 100 to 115 feet. The lifeguards prefer you enter near the Vallecitos Street restrooms when it's busy and in front of the main tower in winter. Stay out of the marked boat-launch lane.

The Marine Room entry

At the south end of the Shores, stairs beside the Marine Room restaurant lead to shallow reefs at 2 to 30 feet toward Devil's Slide. It's the same water where leopard sharks gather in late summer, which makes it a favorite for snorkelers too. The canyon is reachable to the west from about 20 to 30 feet, but Divebums warns that a wrong turn takes you straight out to open ocean.

La Jolla Cove

The Cove is the prettiest dive and the most annoying logistics. Shallow reefs sit at 10 to 20 feet, the giant kelp starts roughly a 100-yard swim out, and the deeper offshore rocks run 65 to 75 feet. Expect garibaldi, horn sharks, sheephead and morays. The City lists visibility sometimes past 30 feet. The cost: street parking that's hopeless after about 7 a.m. in summer, swell on the rocks, and kayak tours overhead.

The rules: look, don't touch

Every site above sits in the Matlahuayl State Marine Reserve or the San Diego-Scripps Coastal SMCA next door. In the reserve, state law (14 CCR 632) makes it illegal to injure, take or possess any living, geological or cultural marine resource. That includes shells and rocks. Spearfishing and lobster hunting happen outside the boundaries, not here. See lobster season rules for where hunting is allowed.
