We were heading to the Flagstaff/GC NP area from a friends house in Arkansas and randomly found Pinion Flats/ The Dunes on a google search. We booked a tent site 1 day in advance for $20ish. When we arrived we just loved everything about this place! What a view! Loop A has great Dunes views. The sites are pretty close together and the restrooms were under construction(outhouses only), but our view was worth it! Check out the map to select a site with a view:) And don’t forget to rent a sled and spend a day on the dunes!
