If Vashon Island itself does not have enough to do, with a ferry ride and a short walk you will find tons of great things to do!
Walking Distance off the South End: (Tacoma)
The South end of Vashon Island has one dock with one destination: Point Defiance, Tacoma. When staying on Vashon Island, folks will often walk onto this ferry (parking lot right above the dock)
Dune Peninsula Park (aka: Chutes and Ladders Park)
Point Ruston (Movies, Shopping and Food)
Walking Distance from the Northend of Vashon Island
The North end of Vashon Island docks sailings from West Seattle as well as Southworth. You can ride the ferry by driving your car or walking on. If you are on Vashon and you want to walk onto the ferry, there is a parking lot on the hill above the dock you can park at. Many folks take the ferry off the North end and then hook up with Public Transit to hit Seattle.
Via Water Taxi (Vashon to Downtown Seattle)
The King County Water Taxi is a foot ferry (no cars) that sails from the North end of Vashon Island directly to Downtown Seattle! Such a great route and a fun ride. Typically they do not run as often as other ferries so check their website for sailing times.
