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.
