One of the best rides around; Kitsap Transit's Carlisle II Foot Ferry.
This 92 year old, beautifully restored and maintained remnant of the Mosquito Fleet is a floating museum as well as a hard working shuttle between the Bremerton and Port Orchard waterfronts.
On a nice day; sitting on the back deck, you'll think you're on a cruise and for $2 it's a bargain.
Take the Washington State Ferry from Seattle to Bremerton, explore the Bremerton waterfront and then hop the foot ferry and explore Port Orchard. A great time to check it out is when one of the many waterfront festivals are in full swing.
