The Keystone Jetty dive site is located near the Keystone ferry dock on Whidbey Island. The dive site is extremely popular, and it features a rocky breakwater that protects the ferry terminal. This dive site is exposed to strong currents, and it is not a place for unskilled divers. Even experienced divers are advised to plan their dives here at slack tide. However, the good point of a stronger current is that it brings an enormous amount of marine life, and the large boulders that make up the breakwater, serve as an ideal habitat for giant Pacific octopi, wolf eels, and many interesting fish species.

When to go

Divers can dive at the Keystone Jetty site throughout the year. However, divers need to use dry suits with thermal undergarments, because the annual water temperature is as chilly as 45-55F/7-13C.

What to see

When diving at this site, divers can see beautiful anemones, orange-colored nudibranchs, Pacific octopi (sometimes five of them in one dive), wolf eels, brown rockfish, lingcod, striped seaperch, and other interesting fish species.
