We stayed here over July 4, 2021. The campground was mostly full until Sunday (July, 4) and then cleared out. It stayed quiet even when full, though. I wondered how rough the roads were, but driving from Castillo to the campground and then on to Hwy 64 east of Cimarron on 1950 was all very doable in a Subaru Ascent towing a trailer despite some heavy rains.
There were pit toilets which were clean, but flies at them got thick as the day warmed up. Flies and mosquitoes were rare at the campsite, though. The campsites were large and surrounded by trees. A few of the outer loop had nice, partial views of the meadow.
There's a nice easy/moderate half mile hike down to the Shuree Ponds which were stocked with trout. it seemed a fair amount of people would drive to the larger of those two ponds for day use fishing. The smaller was reserved for kids's fishing. Both are classied as "Green Chile" waters so only flies or artificial lures with a single, barbless hook are allowed. 2 fish limit.
The area looked like a mecca for wildlife, but we only saw 3 deer in our hikes to and from the ponds and then a muskrat at the pond.
