How to Get to United States Naval Undersea Museum #

The museum is located at Naval Base Kitsap-Keyport on the Kitsap Peninsula, a short drive across the Hood Canal or from the Seattle-Bremerton ferry. From downtown Bremerton, take WA-303 N then State Route 308/Keyport Way; follow signage for Naval Base Kitsap-Keyport and the museum. Limited public transit reaches Keyport - driving or rideshare from Port Orchard/Bremerton is easiest.

Tips for Visiting United States Naval Undersea Museum #

  • Visit on a weekday morning to see school groups leave - the galleries quiet down and the periscope displays become contemplative rather than theatrical.
  • Arrive by car; parking is limited near the museum entrance - follow signs for Naval Undersea Museum at Keyport.
  • Don't skip the small exhibit rooms: models, torpedoes, and oral-history clips often contain the odd human detail that larger displays miss.
