Swamp Lake Trail is a 7.2 mile out and back trail located near Goose Prairie, WA that features a lake. The trail is rated as difficult and primarily used for hiking.
As hikers we found this nice trail heavily impacted by the equestrians with lots of horse dung. It is a nice hike through old growth forest and we did not encounter any equestrians on our midweek hike. The access road FS 1800 is quite rough and rocky - requires a high clearance vehicle for sure.
