Obstruction Pass is a decent campground in the very crowded San Juan Islands. They just build a new self composting toilet that is amazing. The sites are large enough for good size kayak groups. The raccoons where minimal, which says a lot of this area. The sunsets where magical and the campground has 2 beach access points. The downside is it also has drive-in access. Therefore it is crowded and one of the noiser campgrounds in the San Juan area.
