San Juan Wilderness
The tips of submerged mountains collectively thrust above the sea where two straits–Georgia and Juan de Fuca–meet up with Puget Sound, forming the San Juan Islands. Of the 700 or so islands, islets, rocks, and reefs that make up the San Juan Islands, fewer than 200 have garnered official names. The large islands of San Juan, Lopez, Orcas, and Shaw make up more than 80 percent of the landmass. Of the rest of the land, much of it wave-drenched, 83 pieces are included in the San Juan Islands National Wildlife Refuge, a sanctuary for gulls, cormorants, guillemots, puffins, brants, oystercatchers, auklets, bald eagles, and harbor seals.

Boundary map
Boundary, simplified to about 0.005 degrees
The outline is the agency boundary simplified for display, so small parcels and inholdings may not show. The agency page has the authoritative map.
Weather by month
Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
Where to camp
No federal campground is within ten miles of the boundary in the Campsite Atlas index. Camping inside a wilderness is usually allowed away from trails and water, with no facilities; the managing agency page has the permit and group-size rules.
