Snorkeling and Scuba Diving at Keystone Jetty (Fort Casey)

The underwater park at Keystone Jetty is found just South of the Keystone Ferry terminal in the Fort Casey State Park. A small parking area with picnic tables and facilities makes for a nice two-tank location. About 30 miles North of Seattle on Whidbey Island. The location makes for a great loop drive for a leisurely day. The North access to the island is via Anacortes, and the South access is via the Mukilteo Ferry, just West of Everett. About in the middle of the Island, just South of Coupeville, head West on Wanamaker road (highway 20) to the Keystone Ferry landing.

Dove the jetty on 20 Feb. 10. H2O was 44 degrees, out side temp was 55 degrees and sunny, max depth was 57' vis was 25'. Got half way out the jetty and the current grabbed me and pulled me toward the end of jetty. I grabbed a rock and was immediately twisted 180 degrees. I carry a pony tank and the current pulled the regulator right out of its holder attached to my BC. Clawed my way back in and decided to bag it for the rest of the day. This can be a current intense dive spot. About at the 19' mark ran into a GPO (Giant Pacific Octopus) out in the open. It was about three feet long. I surprised it as much as it did me. It inked at me and headed toward the rocks. It then inked again as it went behind and under a rock. I followed it and spent the next ten minutes watching before I got too cold and ended my dive. As always this is a great place to dive.
