Edmonds Underwater Park
Washington · 3–13.7 m
Edmonds Underwater Park (Bruce Higgins Underwater Trails) is one of the oldest and most famous shore-dive parks in the US: a 27-acre marine protected area and no-take sanctuary established in 1970 just north of the Edmonds ferry terminal on Puget Sound. Volunteers led by Bruce Higgins have built roughly 2.5 miles of rope-and-block underwater trails linking sunken structures - the Lopez pontoon, pipes, spools, a dry dock and more - all marked with quirky underwater road signs. Because no fishing or harvesting of any kind is allowed, marine life thrives, most famously the park's enormous resident lingcod. Maximum depth is only about 45 ft, making it a superb beginner and training site, but cold water makes a drysuit the norm.

Eglin Reef 1
Florida · Up to 28.7 m

El Rey
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.

Elephant Butte Reservoir
New Mexico · 3–45.7 m
New Mexico's largest-capacity reservoir on the Rio Grande, named for the volcanic core island near the dam, with maximum depths over 150 feet. It was historically a regional dive destination — divers explore volcanic rock around the butte from shore or rented boats — but years of low water have stirred fine sediment so that visibility is now often only ~3 feet, dropping to near zero below 30 feet. It remains open to diving but is generally regarded as a poor-visibility novelty dive today.

Emerald Bay - Florence M and Boat Camp Wrecks
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.

Emerald Bay Maritime Heritage Trail - Barge Site
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.

Enterprise Cannery
California · 4.6–19.8 m
A shore dive off the north end of San Carlos Beach at the foot of Reeside Avenue, where the remains of Cannery Row's sardine industry — including a large submerged pipe once used to transfer sardines from boats to the canneries — now serve as a navigation line across a rock-and-sand patch reef. The rocky reef supports one of the thickest remaining giant kelp beds in Monterey, and the pipe leads seaward to rock piles and the famous Metridium Fields of giant plumose anemones at about 65 ft. Protected, easy entry and abundant macro life make it a favorite relaxed dive and training area inside the Ed Ricketts State Marine Conservation Area (no take).

F. T. Barney Wreck
Michigan · 43–49 m
The F. T. Barney is a 126-ft two-masted wooden schooner built in 1856 that sank in under two minutes after a midnight collision with the schooner T.J. Bronson on October 23, 1868, settling gently in 160 ft of Lake Huron off Rogers City. Rediscovered in 1987, she is one of the Great Lakes' most intact schooners, with an erect mainmast, intact stern cabin, and a cargo hold still full of coal — the first Lake Huron shipwreck listed on the National Register of Historic Places. The depth makes her a prized technical dive.

Falling Rock Park (La Grange Quarry)
Kentucky · Up to 16.8 m
A flooded former limestone quarry near La Grange operated as an adults-only (18+) commercial swim and dive park, about 30 minutes from Louisville. The rain-fed water is unusually clean for a quarry, with visibility commonly 20 ft or better, and the basin drops to 55+ ft with limited shallow areas. Originally developed as a diver training facility, it remains a staple checkout-dive site for Louisville-area shops.

Farnsworth Bank
California · 16.8–39.6 m
Open-ocean seamount about 1.5-2 miles off the backside (southwest) of Catalina Island, with pinnacles rising from 200+ ft to peaks around 55-60 ft. It is famous for dense stands of protected California purple hydrocoral covering the walls, with most diving in the 90-110 ft range. Exposed position means it is only diveable in calm seas, and currents can be strong; the site is protected within the Farnsworth Offshore State Marine Conservation Area.

Fire Island Reef
New York · 18.9–22.3 m
Fire Island Reef is an 850-acre NYSDEC artificial reef about 2 nautical miles south of the Fire Island Lighthouse in 62-73 ft of water. It holds dozens of scuttled vessels, barges, pontoons, drydocks, Tappan Zee Bridge materials, railcars and concrete forms, with ongoing deployments (concrete forms added 2025). Black sea bass, tautog and scup are abundant; visibility runs 10-20 ft, an intermediate Atlantic boat dive.

Five Caves / Five Graves (Makena Landing)
Hawaii · 3–15.2 m
South Maui's signature shore dive off Nahuna Point near Makena Landing, also called Turtle Town. A reef honeycombed with caves, arches and ledges in 10-50 ft where green turtles rest and whitetip reef sharks pack the 'shark condo' cavern. Usually entered from the sandy ramp at Makena Landing Park with a surface swim, or directly off the rocky shoreline at Nahuna Point.

Flaming Gorge Reservoir (Cart Creek Bridge / Mustang Ridge)
Utah · 3–30.5 m
A huge, deep, clear reservoir on the Green River near Dutch John with some of Utah's best freshwater visibility (20-40 ft). Established dive areas near the dam include the Cart Creek Bridge wall dive, Mustang Ridge, the Visitor Center shoreline, and the islands (Osprey/Gilligans) with walls and pinnacles. The reservoir is over 400 feet deep in places, so divers pick their depth on the walls; below the thermocline it gets dark quickly.

Flathead Lake - Goose Island
Montana · 6–30.5 m
The largest natural freshwater lake in the western U.S., Flathead Lake offers clear water with visibility often exceeding 100 feet and depths over 300 feet, drawing divers to its rock formations and underwater cliffs. Goose Island, a glacial rock outcropping ringed by boulders and fish, is a highlight, and several boats have been deliberately sunk to create fish habitat and dive attractions. Somers Bay on the north end holds the upside-down hull of the Kee-O-Mee, a 54-foot pleasure boat that sank in 1937, along with the remains of the old Somers Mill.
