We’ve stayed at this campground twice now in the tent-only loop (sites 40-45). The tent-only sites are walk-in, so you park at the top of a small hill and walk down to your site. It is beautiful! Sites are same-day reservation only, so you have to call the campground number starting at 6:00 MT to see if any spots are available. There’s some awesome trails you can access from the campground. There’s a swimming beach for the lake, and a small park for kids. Vault toilets and hot showers are available. Custer State Park is truly a gem.
