Best dive sites in Washington, United States

Showing 1–15 of 15

Alki Junkyard / Pipeline

Washington · 3–18.3 m

A pair of adjacent shore dives off Beach Drive SW on the south side of Alki Point in West Seattle, distinct from the better-known Seacrest coves. The Junkyard is a debris field of old car bodies, machinery and scattered junk that now functions as artificial reef and octopus habitat, while the Pipeline follows an old outfall pipe over a gentle slope to about 40 ft. Entry is from street ends near Richey Viewpoint with a stair/ramp walk-in and a shallow swim-out.

Shore entry

Blake Island Reef

Washington · —

Blake Island Reef is a dive site located in United States.

Day Island Wall

Washington · 12.2–33.5 m

A natural sandstone wall at the south end of the Tacoma Narrows near Day Island, just south of Titlow Beach. The sheer main wall runs south of the entry to about 110 ft, with shallower ledges and cutbacks in 40-55 ft to the north and a reported deeper wall starting around 100 ft and running to roughly 140 ft. Swift Narrows currents carve dens that shelter numerous wolf eels and giant Pacific octopus, but the same currents make this an advanced, slack-only dive planned around minor exchanges (max ~2.4 kt predictions); current along the wall runs opposite to the mid-channel flow.

AdvancedShore entry

Deception Pass

Washington · 6.1–24.4 m

The narrow channel between Whidbey and Fidalgo Islands where Skagit Bay meets the Strait of Juan de Fuca, with tidal currents that can scream through at up to 8 knots. The huge water exchange feeds some of the most densely colorful invertebrate-covered walls in the Pacific Northwest, but the site is diveable only on a handful of minimal-exchange slack windows scattered through the year, and true slack can fail to materialize. Whirlpools, downwellings and instantly reversing current make this an expert-only dive, usually done with boat support and local knowledge.

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.

Shore entry

Keystone Jetty (Fort Casey Underwater Park)

Washington · 3–18.3 m

Washington's other underwater state park, along the rock jetty protecting Keystone Harbor at Fort Casey State Park on Whidbey Island, next to the Coupeville-Port Townsend ferry landing. The jetty boulders are plastered with anemones and nudibranchs and shelter wolf eels, octopus and big lingcod, with about 55-60 ft of depth at the jetty tip. Admiralty Inlet currents sweep the site hard, so it is strictly a slack-water dive planned with Admiralty Head current predictions, and divers must never round the jetty into the active ferry lane.

IntermediateShore entry

Les Davis Marine Park

Washington · 6.1–36.6 m

A Metro Parks Tacoma fishing pier and marine park on Ruston Way in Commencement Bay with a dedicated diver stairway. A short ~75 ft swim from the stairs reaches a large man-made reef built partly from blocks of the original Tacoma Narrows Bridge, lying perpendicular to shore in roughly 40-70 ft, with the bottom continuing past 120 ft for deeper profiles. Mild conditions, easy entry and on-site amenities make it one of Tacoma's most popular training and night-dive sites.

IntermediateShore entry

Mukilteo T-Dock (Lighthouse Park)

Washington · 3–36.6 m

A long-running training and night-dive site beside the Mukilteo ferry terminal and Lighthouse Park, entered from the beach next to the Silver Cloud Inn. A gradual sand slope passes pilings and placed attractions - most famously a PVC-pipe geodome at roughly 50-70 ft - and keeps dropping past 100 ft, making it popular for deep and tech training as well as open-water classes. The original T-shaped dock was removed during ferry terminal construction in the mid-2010s, but the geodome, debris reef and abundant critters remain.

AdvancedShore entry

Octopus Hole

Washington · 6.1–18.3 m

A WDFW conservation area on Hood Canal right off Highway 101, just over three miles north of Hoodsport and a short drive from Sund Rock. A roughly 200-yard-long rock wall starts around 40 ft and drops to 50-60 ft depending on tide, riddled with cracks and dens that house giant Pacific octopus and wolf eels. Currents are mild, making it a relaxed wall dive, but no hunting or gathering of any kind is permitted.

Shore entry

Redondo Beach (Des Moines)

Washington · 3–30.5 m

One of the most popular training and night-dive sites in south Puget Sound, on the Redondo waterfront boardwalk in Des Moines next to the MaST Center aquarium. A gentle sandy slope holds guide ropes (shallow line ~50 ft, deep line ~100 ft), sunken boats, a VW bug and other debris that act as artificial reef. It is famous for muck-style critter hunting - red octopus, stubby squid and Pacific spiny lumpsuckers on night dives - with easy stair entry next to the boat ramp.

AdvancedShore entry

Salt Creek Recreation Area (Tongue Point)

Washington · 3–12.2 m

Often called the best shore diving in Washington, this Clallam County park sits on the Strait of Juan de Fuca about 13 miles west of Port Angeles beside the Tongue Point Marine Life Sanctuary. Rocky reef fingers, kelp beds and surge channels hold open-coast life rarely seen inside Puget Sound, with most diving in the 20-40 ft range beyond the kelp line. It is an advanced, ocean-exposed site - swell, surge and thick kelp demand careful timing - and the easiest of the three diver access points is the staircase beside campsite #63.

AdvancedShore entry

Seacrest cove 2

Washington · 3–27.4 m

Seacrest Cove 2 ('Alki Cove 2') at Seacrest Park in West Seattle is one of the most-dived sites in Washington and the unofficial heart of Seattle's dive community. A gradual rocky slope descends past artificial structures - the famous Honey Bear wreck around 35 ft, I-beams, small boat wrecks and junk piles - that shelter the site's headline residents: giant Pacific octopuses. The cove lies within the WDFW Alki Beach Seacrest Coves 1, 2 and 3 octopus-harvest preserve, created after a controversial 2012 octopus take here. Easy stair-and-beach entry, minimal current, free street parking and city skyline views make it ideal for training and night dives, but it is genuinely cold - drysuits are the norm.

IntermediateShore entry

Sund Rock Marine Preserve

Washington · 4.6–30.5 m

A designated conservation area on the west shore of Hood Canal about 2 miles north of Hoodsport, widely considered one of Washington's premier shore dives. Two main walls (north and south) drop to 70-80 ft with deeper walls beyond 100 ft for technical divers, plus a sunken boat north of the north wall and a small wreck between the walls. The site is not current-sensitive, and resident giant Pacific octopus and mated wolf eel pairs are the headline attractions.

AdvancedShore entry

Three Tree Point

Washington · 6.1–27.4 m

A residential beach-access dive in Burien at the prominent point (Point Pully) between Seattle and Des Moines, dived from the small public access on the north side. Cobble and boulder reef begins around 30 ft and gives way to sand at 80-90 ft, with octopus dens, ledges and scattered debris; an old telegraph cable and bottle areas add interest. Access is a gated dirt path to a concrete bulkhead with almost no amenities, and the beach either side of the access is private property.

IntermediateShore entry

Titlow Beach

Washington · 4.6–12.2 m

A marine preserve at Titlow Park on the Tacoma Narrows, where the pilings of an old ferry dock are carpeted in white plumose anemones. Most of the dive sits in 25-40 ft over the piling field, a decayed barge and a bottle field, with small rock ledges to the south that hold wolf eels. Because the site sits in the Narrows it must be dived at slack using Tacoma Narrows current (not tide) tables, but at slack it is an easy, life-rich beginner dive.
