With the largest ferry fleet in the United States, the Washington State Ferry system operates 22 boats. Lining up to drive a vehicle onto the deck of the vessel is just the beginning of a truly Northwest experience. Onboard, get out of the car and enjoy educational and interpretive signage around the ship. Grab a latte or hot chocolate to warm your hands, and step out into the brisk salt air on the open passenger deck to take in the passing bay, mountain and island views. Just two possible itineraries for a day trip to explore Puget Sound from the main Seattle terminal include the Seattle-Bainbridge Island Edmonds run or the route for Fauntleroy-Vashon Island-Edmonds. The fleet's biggest boats travel between Seattle and Bainbridge; the island offers a combination of rural charm and sophisticated amenities. Fares vary seasonally by route.
