About San Juan Island
The San Juan Islands are an archipelago of about 172 named islands. Surrounded by the Salish Sea and Seattle, Vancouver B.C. and Victoria, the Islands offer a diversity of authentic experiences that parallel its natural wonder. San Juan Island, the largest in population of the four ferry served islands, has a population of 5,214 residents and 2,150 additional residents that reside in Friday Harbor. San Juan Island is approximately 55 square miles. Friday Harbor, the county seat, located steps from the ferry terminal is steeped in history.
