San Juan Islands (Washington)

The San Juan Islands occupy the corner of Washington state where Puget Sound meets the Strait of Juan de Fuca and the Canadian border. The archipelago contains over 170 islands — four of them large and inhabited, the rest a mix of state parks, nature reserves, and private land — scattered through channels where tidal currents can exceed four knots and resident orca pods hunt salmon within sight of anchored boats. Bellingham, on the mainland, is the primary charter base. The marina at Squalicum Harbor handles the fleet, and the town — a former lumber and fishing port now home to Western Washington University — provides provisioning and a reasonable restaurant scene. The passage from Bellingham into the islands takes a few hours, passing through Bellingham Channel to the San Juan group. Friday Harbor, on San Juan Island, is the commercial and social centre. The harbour has a marina, a whale museum, and a main street of shops and restaurants that cater to the summer visitor trade. From Friday Harbor, the standard itinerary circuits the main islands: Orcas Island, the largest, with a mountaintop view from Mount Constitution; Lopez Island, the flattest and most agricultural, known for its cycling and its farm stands; and Shaw Island, the smallest and quietest of the four. The wildlife is the archipelago's marquee feature. The Southern Resident orca population — three pods totalling roughly 75 animals — uses the channels between the San Juan Islands and the Canadian Gulf Islands as feeding grounds. Sightings from a sailboat, particularly along San Juan Island's west coast at Lime Kiln Point, are realistic during the summer salmon run. Harbour seals, bald eagles, and great blue herons are daily sightings. The tidal currents in the channels — particularly in Cattle Pass between San Juan and Lopez, and in Rosario Strait — demand respect. Current tables and passage timing are essential; fighting a four-knot current under sail is futile. The water is cold — 8-12 degrees — and fog can appear with little warning, particularly in the Strait of Juan de Fuca. Provisioning in Bellingham and Friday Harbor is straightforward. Orcas and Lopez have smaller stores. Fuel and water are at the main marinas. The season runs June through September; July and August are warmest and driest.
