Arch Rock Campground — Keyhole State Park

1 ReviewAdd Review
SUMMARY PRESENTED BYT-Mobile

Sitting directly on the shore of Keyhole Reservoir, Arch Rock Campground gives campers immediate water access from their site. The terrain runs hilly, and at least some sites require carrying gear in rather than pulling up directly. At $10 a night, it is one of the more affordable options managed by Wyoming State Parks, with picnic tables, campfire rings, cell service, and ADA accessibility on-site. Pets are welcome, and reservations are available. The campground sits within camping near Keyhole Reservoir State Park, alongside nearby alternatives like Tatanka Campground — Keyhole State Park just 0.3 miles away. Anglers and water-focused campers will find the lakeside position the main draw here.

Beautiful...Stayed for one night

My husband and I enjoyed staying here. We wished it had been pull up and not carry in but it wasn't too bad. Also, it was very hilly. We were right by the water and it was beautiful! We would come back.
