No reservations but lots of options if you explore around the dirt roads a bit. Buckhorn wash is beautiful but very bumpy.

It is all first come first serve. FCFS camping is also along the road North of Good Water Canyon, not just at the Wedge.

No reservations there. First come first serve and a 15-2mile dirt road to access it.

Short answer 'Nope" For future reference, when it's BLM land if Open camping, no RSVPs.. FCFS (First Come, First Serve) and typically BLM is free for 14-days then have to move a certain number of miles away, ~28 mi or like that. But NO Reservations. Some BLMs have improvements like a BBQ, Fire Pit and Shade canopy and charge ~$5 Hope that helps...

There are no reservations for this area but i do not think it would ever fill up. Remember, driving into Wedge Overlook is a washboard road and at one point very challenging for any vehicle of length as the road peaks up and curves. I was in a 28 ft Class C.

It's entirely first-come, first-served.
