This Cold War-era Russian submarine is berthed just south of Washington State Ferries' Colman Dock at the south end of the waterfront, and the long black submarine is an ominous sight on this touristy stretch of Seattle shoreline. The sub, code-named Cobra, was built in 1972 and was in service for 20 years. After watching an introductory video, which provides a bit of background on Russian submarines, you will board the sub for a self-guided tour of the main deck. An audio recording explanins what you are seeing as you walk through. For anyone who lived through the Cold War, it is exciting just to be inside a sub that was once considered "the enemy." The admission is $10 for adults and $8 for seniors and children.
