A mosaic of islets, rocky headlands, and historic light stations strung across the Salish Sea. The monument protects habitat for black oystercatchers, marbled murrelets, and charismatic marine mammals like orcas and river otters. On wind-whipped points, century-old lighthouses still stand sentinel. Kayakers paddle shoreline corridors rich with bull kelp, while shore-based visitors scan for bald eagles and migrating gray whales. The scenery shifts with the tide, offering a coastal Pacific Northwest experience shaped by salt spray, island forests, and open water.
Best season — Late spring through early fall offers calmer seas for paddling and better odds of seeing orcas. Summer brings wildflowers on grassy bluffs and extended daylight, though fog can roll in unexpectedly. Weather is mild but changeable; the off-season suits solitude seekers who don't mind the mist.
