Blake Island

A beautiful 475-acre state park near Seattle reached by sea kayak, ferry or private boat. It has eight miles of hiking trails, and a four-mile loop trail around the island's waterfront offers spectacular views of the Seattle skyline, Mount Rainier, and the Olympic mountains. Black-tailed deer and bald eagles are commonly seen. Three beach campgrounds offer overnight accommodation. A nice outing when a sea kayak to the island and hike or backpack trip around the island are combined!

about the island

Blake island is one of the most scenic state parks in the Seattle region and an ancestral area of the Suquamish Tribe, whose Chief Seattle, the city’s namesake, was born here. Nestled between Vashon and Bainbridge islands, this lesser known jewel is four miles from Alki Point, about a 45-minute ferry ride from Seattle. 

  • The 475-acre island park contains an eight-mile trail system. The main trail circumnavigates the island in a four-mile loop.
  • Three beach campgrounds at the east, south, and west corners of the island provide campgrounds for overnight trips.
  • The north corner of the island houses the marina and Tillicum village, which can get crowded during the summer  tourist season. The rest of the island is highly underused even during peak season.
