San Juan County, Washington

San Juan County is a stunning island destination in the Salish Sea, located northwest of Seattle near the Canadian border. The county consists of 172 named islands, although ferry service is available to only four of them.

The surrounding waters are home to orcas, while bald eagles can often be seen soaring above the islands. Life moves at a slower, more peaceful pace here, with kayaking, whale watching, beachcombing, and relaxing by the water among the favorite activities.

Friday Harbor, located on San Juan Island, is the county’s largest community and a charming tourist destination. Hiking and biking are popular ways to explore the islands, with breathtaking views of forests, mountains, and sparkling waters around nearly every corner.
