About
San Juan County campground on the west side of San Juan Island, facing Haro Strait. Tent and small-RV sites with no hookups; RVs up to 25 feet fit only in sites 6, 7, 10 and 15, and there is no dump station. The county's fee schedule lists sites by number rather than as a total. Open year-round: summer (April 1-October 31) sites reserve online, while in winter (November 1-March 31) camping is first-come, first-served and some sites close.
