Was here in late June and stayed in Mallard Loop #10 right across from the bathroom. Fantastic camping area with widely spaced sites, great views of the lake and excellent facilities. Stayed in an RV only area, but there were 20+ tent only sites in another camping area that looked as nice as the one I stayed in. I would definitely return if ever back in the area.
Visited in late July and the temps were not bad in the 80's. Nice little campground with no hook ups. One flush toilet per gender and a couple of pit toilets. Open sites great for tents. Right by the Pecos River with fishing. Saw several people with stringers of nice brown trout. No cell service here. Hiking trails are several miles drive away.
Well off the beaten path, but worth a few nights of peace and solitude. Went in July and the weather was cool in the 80's most of the time, cooling to the upper 40's at night. Isolated at the end of a road in the edge of the Monzano Mountains, it is fully treed with great shade. Good place for an RV or tent. Nice hiking (easy) trails. Flush toilets but no showers. Dump station. Very nice facility.
Have visited several times over the years. Pretty cool even in the hottest of summers, yet warm during the winter months. Great spot to base camp for hikes into the Guadalupe Mountains! Flush toilets but no showers. Tent pads and fresh water nearby. Love to watch the hummingbirds at the headquarters porch fighting over the feeders. No cell phones to bother you here, just peace and quiet. A bit off the beaten path, but well worth the trip.
