Closest Park to Marfa town center
This place is right next to El Cosmico which is the well-known (and high-priced) option in town. These grounds are very basic, with lots of older trailers and full-timers in most of the occupied spaces. While not the most luxurious place, the real draw is the fact that you can walk into town and explore Marfa from your campsite (and the Chianti Foundation is very close by, but closed during COVID).
Basic amenities are available including a laundry room and sites have full hookups. It's not the fanciest, but if you're looking for location over luxury, this is a great spot to park in Marfa.
