The San Juan Islands are made up of 4 islands (San Juan, Orcas, Lopez, and Shaw). I visited the most inhabited island, San Juan, on a weekend attached to visiting Mount Vernon, WA for the annual Tulip Festival in April. From the ferry terminal in Anacortes (northwestern Washington), it takes about an hour and a half to Friday Harbor, the main port on the island. One of the best moments of my life was on San Juan at the Cattle Point Lighthouse.
