About
Lost Prairie Group Site sits at 3,600 feet in the Willamette National Forest along the Over the Rivers and Through the Woods Scenic Byway. The campground occupies a natural meadow near Hackleman Creek, historically part of the Santiam Wagon Road where a scouting party famously became lost before spotting Sand Mountain. Summer brings wildflowers blooming in the prairie, and the creek is accessible from the campground. The site accommodates up to 75 people across 10 campsites. Sites 1-4 are paved back-in sites suitable for RVs and trailers ranging from 15 to 42 feet depending on the site. Sites 5-10 are former walk-in sites within 60 feet of the main area, ideal for tent camping. A paved parking area accommodates up to 6 RVs. Each site has a picnic table and fire pit. Two double vault toilets serve the campground, including one ADA-accessible unit near the parking area, plus an older outhouse near site 1. Drinking water is available from a hand pump well. The location offers excellent access to outdoor recreation. The McKenzie River National Scenic Trail is 15 minutes away, and Clear Lake, known for its exceptional clarity and submerged standing trees from the Sand Mountain eruption, is nearby with a resort offering boat rentals and dining. Iron Mountain, Echo Basin, Crescent Mountain, and Browder Ridge trails are all within a short drive, while Smith Reservoir and Suttle Lake provide additional boating and fishing opportunities.
