Ocotillo Grove 1 (OG-1) campsite is located off of Old Maverick Road, 3 miles from the southern end near Santa Elena Canyon, or 10 miles from the northern end near the Maverick Entrance Station. Look for the site on the north side of the road on the way to Terlingua Abajo.
Good place on the west side to camp. Site is reasonably secluded and close enough to the canyon. Great views all around. Found some hog wallows tucked into the small hills to the west. Large enough to get a camper van into and turn around.
Great location, lots of great views. Yes, you can put a larger travel trailer into the site. The trick is to drive past the entrance then back in. We put a 22.5 ft hard side trailer in there, it would be easier if we didn't have another RV in the same site that was illegally camping and claimed they were "broken down". We towed it with an BMW X5M SUV
