San Juan Islands Wilderness Area

San Juan Islands Wilderness Area is a 380-acre federally protected Wilderness in Washington, managed by the U.S. Fish and Wildlife Service. This primitive backcountry offers solitude and untrammeled landscape in a marine island setting, where visitors encounter the character of the San Juan Islands without mechanized access or development.

Recreation here is non-motorized and human-powered: hiking and backpacking are the primary pursuits, along with kayaking and wildlife viewing for those approaching by water. Like all designated Wilderness, the area is off-limits to roads, motors, and mechanized travel. Visitors must practice Leave No Trace ethics—pack out all waste, camp only in designated areas where allowed, and travel lightly on the land.

Access requires planning; there are no trailheads or services within the Wilderness itself. Most visitors arrive by private boat or commercial ferry service to the San Juan Islands, then access the protected lands on foot. Weather and water conditions govern the season; late spring through early fall offers the most reliable window for travel, though tides, currents, and marine weather demand respect year-round. Permits may be required—check with the U.S. Fish and Wildlife Service before your trip.
