California · 6–21 m
Historic three-masted steel sailing ship wrecked on Talcott Shoal off Santa Rosa Island. NOAA and NPS materials document underwater wreck imagery, making this a legitimate Channel Islands boat-wreck target for experienced cold-water divers. Expect scattered wreckage integrated with reef/kelp habitat rather than a complete ship.
California · 8–20 m
Historic passenger-cargo steamer wreck off Point Bennett, San Miguel Island. NOAA/NPS and NOAA-authored dive writing confirm underwater remnants and diver interest, with machinery and organized wreckage remaining in a swell-exposed sanctuary setting. This should be treated as a cold-water boat wreck for capable divers, not a casual shore site.
California · 3–9 m
Shallow historic four-masted bark wreck along the southwest coast of Santa Rosa Island. NOAA and NPS document underwater wreck imagery; the site is best represented as a protected Channel Islands boat wreck with scattered remains and cold-water exposure. Keep the record concise and avoid repeating unverified cargo/history embellishments.
California · 3–9.1 m
Shallow historic side-wheel steamer wreck at Middle Anacapa Island, protected within Channel Islands National Marine Sanctuary and National Park. Divers mainly see machinery/paddle-wheel remnants and growth-covered wreckage in kelp-reef habitat rather than an intact hull. This is a boat dive with cold-water exposure and protected-resource rules.
California · 3–30.5 m
Casino Point Dive Park (Avalon Underwater Park) is a roughly 2-2.5 acre roped-off, no-take marine reserve beside the landmark Catalina Casino in Avalon, widely regarded as the best shore dive in California. Custom concrete stairs with handrails lead straight into a lush giant kelp forest over reefs, mini-walls and sand flats from 10 to 100 ft, with several small wrecks including the 54-ft sailboat Suejac (bow at ~95 ft), the Kismet, a glass-bottom boat and a sunken swim platform, plus an underwater Jacques Cousteau memorial plaque at about 35 ft. Established in the 1960s as the first non-profit underwater park in the country, its protected status makes the fish unusually bold and the site ideal for everyone from open-water students to photographers.
California · 6.1–25.9 m
A large white-domed rock at the edge of Isthmus Harbor near Two Harbors, offering varied terrain: shallow reef, an underwater arch, and a wall that drops vertically from about 20 ft to 70 ft, with another section running from the surface to 85 ft with deep undercuts. Scattered boulders and kelp continue to 60-80 ft. The boundary of the Blue Cavern Onshore State Marine Conservation Area cuts through the reefs here, so most divers treat it as a no-take site.
California · 4.6–27.4 m
An advanced Carmel shore dive named for the private home with a butterfly-shaped roofline on Scenic Road south of Carmel Point. A steep winding path leads down the cliff to a rocky staging area and tricky entry, beyond which lie granite reefs, sand channels and a rich giant kelp forest with depths dropping from 15-20 feet near shore to 60-90 feet within kicking range. The site is exposed to swell from nearly every direction and should only be dived on very small swell.
California · 6.1–18.3 m
A long, gently sloped beach at Carmel River State Beach, far more forgiving than neighboring Monastery Beach. The bottom drops in rocky steps from 20 to 30 to 40 feet and then slopes past 60 feet, beneath one of the healthiest kelp beds in Carmel Bay — often too thick to surface-swim through in summer and fall. Enter and exit at the very north end near the Scenic Road stairs.
California · 3–7.6 m
Carnelian Bay, on Tahoe's north shore at Patton Beach/Waterman's Landing and Carnelian West Beach, is a free, year-round beginner site named for the reddish carnelian stones found along the shoreline. A very gradually sloping sandy bottom averaging 20-25 ft holds a scattering of semi-historic debris — a sunken barge, engine blocks, deteriorating fishing boats and enormous logs — with 50-60 ft visibility typical. It is the lake's most popular summer night-dive site, alive with crawfish, sculpin and rainbow trout after dark.
California · 6.1–21.3 m
One of the best-known dive sites in Channel Islands National Park, on the sheltered north side of East Anacapa Island about 1-1.5 hours by boat from Ventura. Reef structures top out around 20 ft and drop to 70+ ft sand channels, draped in giant kelp with arches and cavern-like formations, abundant gorgonians and a nearby sea lion rookery. The site lies inside a long-established no-take marine reserve, so fish life is dense and giant sea bass are seen with some regularity.
California · 6.1–10.7 m
A shallow rocky-reef shore dive off the seawall-protected beach in La Jolla, with depths around 30 feet and an easy entry aided by the wall's sheltered pool. Famous for its resident seal colony; the beach is closed to public access during the winter-to-spring seal pupping season, and surge over the reefs demands calm conditions.
California · Up to 15 m
China Cove is a sheltered, sandy day-use beach on the southern shore of Donner Lake inside Donner Memorial State Park near Truckee, and the lake's best-known easy shore dive. The clear, cold cove bottoms out around 40-50 ft with visibility commonly in the 50-60 ft range, making it a relaxed beginner altitude dive with crawfish and trout over sand and granite. Picnic tables, BBQs and seasonal restrooms sit right behind the beach; a state park day-use fee applies.
California · 6.1–27.4 m
A Carmel Bay shore dive at the south end of Carmel Beach, named for the distinctive copper-roofed home above the entry. A staircase leads to the beach, and divers enter on the far left (south) side near the rocks, working out to kelp-covered granite reefs and an outer reef in 20 to 90 feet of water. Easy on flat days but quickly becomes an intermediate-to-advanced site when swell wraps into the bay.
California · 3–15.2 m
A gravel pocket beach at Ocean View Boulevard and Coral Street in Pacific Grove, near Point Pinos. Beyond the eelgrass-covered boulders of the shallows, the bottom forms a sawtooth pattern of rocky ridges and sand channels running parallel to shore, rich with invertebrate life and coralline algae. The shallow rocky approach makes it a high-tide dive, and it is more exposed than the sites inside Monterey Bay.
California · 4.6–19.8 m
Scenic Laguna Beach cove with sandy entry and rocky reef structure on both sides, with most points of interest in 15-35 ft. Strong swimmers or kayak/boat divers can continue roughly 300-400 yards offshore to Deadman's Reef, a pinnacle complex rising to about 20 ft with 45-65 ft on its flanks. The site lies inside the no-take Laguna Beach State Marine Reserve.
California · 6.1–15.2 m
The most popular dive access within Crystal Cove State Park, reached by a long trail and ramp down from the Reef Point parking lots. Distinctive tilted rock fingers run offshore, with the best reef structure in roughly 30-50 ft straight out from the rocks, and a 150-year-old historic anchor sits in about 20 ft near the Muddy Creek ramp. The area lies within the Crystal Cove State Marine Conservation Area, which restricts take of most invertebrates.
California · 3–12.2 m
Small, protected sandy cove off Cliff Drive in Laguna Beach with a series of mini-reefs beginning almost immediately offshore in 10-35 ft of water. It is one of Orange County's most heavily used open-water training beaches and can be combined with adjacent Fisherman's Cove as a loop dive. The cove sits inside the no-take Laguna Beach State Marine Reserve.
California · 4.6–24.4 m
The designated diving area of Point Lobos State Natural Reserve, comprising Whalers Cove and Bluefish Cove south of Carmel — widely regarded as the best diving in the Monterey area. The reserve has been fully protected for decades, so fish are large and unafraid, kelp forests are pristine, and access is capped at ten buddy teams per day via a State Parks reservation system. Entry is an easy concrete boat ramp into sheltered Whalers Cove (15-80 ft), with more dramatic walls and pinnacles in Bluefish Cove reachable by long swim, kayak, or small boat.
California · 18–26 m
The El Rey is a 100-foot, 133-ton kelp-harvesting vessel that cut kelp for Kelco for 41 years before being scuttled by a Navy demolition team on April 2, 1987, becoming the first ship sunk in San Diego's Wreck Alley off Mission Beach. She sits in roughly 75-85 feet of water and is densely overgrown with red gorgonians and strawberry anemones. A compact, easily navigated wreck often paired with the Ruby E or Yukon on two-tank charters.
California · 5–18 m
Part of California's first underwater maritime heritage trail, opened in Emerald Bay State Park in 2018. This stop features the Florence M, a 27-foot passenger launch built in 1915 at Stephens Brothers boatyard that ferried Emerald Bay Resort guests from 1926 and now sits in about 60 feet of water, plus two small sunken fishing boats near the boat-in campground. The collection is the largest, most diverse group of small sunken watercraft in their original location known in the United States. High-altitude freshwater diving with often excellent visibility.
California · 3–12.2 m
The Historic Barge Site is the anchor of the Emerald Bay Maritime Heritage Trail, California's first underwater maritime heritage trail, opened by California State Parks in October 2018 within the Emerald Bay State Park underwater area (designated 1994). Two massive Ponderosa-pine lumber barges — once towed by steamers to haul cordwood and ferry cars — rest in about 10-40 ft of water off the bay's southeastern shore, the more intact southern barge measuring over 100 ft long, alongside a historic resort-era dump site. The collection is part of the largest, most diverse group of sunken small watercraft in their original location known in the nation; all artifacts are protected by state law. Access is advised by boat due to the remote location, and the over-6,000 ft altitude plus year-round frigid water demand proper planning.
