Shore-access pier dive with crabs, octopus, and traffic.
Boeing Dock is a shore-access pier dive on Mukilteo's working waterfront, where pilings, dock structure, and a steep waterfront slope create a compact local dive. The site is valued more for crabs, octopus, and mixed small life around the structure than for open-water scenery, and planning matters because ferry, barge, and dock activity can change the feel of the dive quickly.
Site Conditions
Safety Notes
Use extra caution around ferry, barge, and dock activity; keep your exit plan simple.
Access Restrictions
Use the beach-park approach and avoid the active dock lane when vessels are moving.
Legal Notes
Treat the dock as a working waterfront and follow local access rules so you do not interfere with dock operations.
Community notes to help plan your visit.
Scuba Diving
A pier-structure dive with pilings, a steep slope, and a more interesting open-water side when traffic is calm.
Freediving
The shallow edge may suit experienced freedivers, but traffic and current make scuba the better fit.
Snorkeling
Snorkeling is limited to the shallowest edge and is not the main use case.
