This is BLM land that's free to camp on for up to 14 days every 45 days. The camp sites are just off a dirt road that leads to the trailhead for hiking to Blanca Peak. The road gets pretty rough the further up you get, but there are plenty of large camp sites on the way up the mountain, some you'd have to home to if you decide to go to Blanca Peak. It's a fairly busy place as off-road vehicles and horse back riding are popular here. Beautiful views of the San Luis Valley, Great Sand Dunes National Park, and Mt. Blanca. Definitely worth checking out of you're in the area. No shade or amenities, so bring everything you need with you and as always, leave no trace.
