Picture an island with turquoise inlets and craggy coves. The northern San Juan Islands may not come to mind at first, but Stuart Island Marine State Park could surprise you.

Stuart Island, near the U.S.-Canada border, is one of the northwestern most islands in the famed archipelago, and you can only reach it by boat.

Anchored in two harbors, boaters mingle as they fish, crab, dive or swim. Hikers can walk up to higher ground or hoof it to the Turn Point Light Station outside the park. Canoeists and kayakers can pitch their tents in the primitive campsites near Prevost Harbor or on the spine of the island. In the evening, all faces turn west as the sky glows red and the sun falls below the horizon.

Whether you expect it or not, you will find a little bit of Paradise (and a friendly boating community) at Stuart Island Marine State Park.
