Not a lot to do here but what you can do is pretty cool. Sledding and hiking through the dunes is sandy but fun. Compared to sand, gypsum isn’t as hot so you can go barefoot, even in the hotter times. Nearby Townes are pretty dumpy but a stay in nearby Cloudcroft would be the ideal way to break up a road trip here. 

We paired this trip from El Paso to Guadalupe mountains, Carlsbad caverns (another unesco site) and White Sands
