About this site
Keystone Jetty offers a thrilling drift dive along a rocky breakwater in Puget Sound. Strong currents bring nutrient-rich waters, attracting giant Pacific octopus, wolf eels, and colorful nudibranchs. The structure is covered in plumose anemones and vibrant sea stars. Depths range from 20 to 60 feet, with excellent visibility on incoming tides. Cold water diving requires proper thermal protection. The jetty's crevices hide abundant marine life, making it a macro photographer's dream.
