Site details

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.

muckshore

Cold Puget Sound water year-round (45-55 F) - hypothermia risk without proper exposure protection. Adjacent Washington State Ferries terminal immediately south — never cross the park's southern boundary into the ferry lane. Entanglement potential around rope trails, ropes and sunken structures. Variable visibility (often 5-20 ft, worse after storms/plankton blooms). Shallow park is best dived at higher tides; very low tides leave little depth and a long walk. Mild currents only - the park is well protected.
