We drove 8 hrs from Dallas to Big Bend hoping to stay at Chisos Basin but heard it was full so the park ranger suggested Rio Grande for the night. We got to the campground which has tons of sites but many of the sites that were covered and more private were taken. We actually had a rough experience to start with when we started to set up our tent only to find out someone paid for the site and left without leaving anything to show it was already taken. The majority of sites were wide open and felt like a state park rather than a comfortable campground. There were lots of trees and it got really dark but couldn't see the stars clearly through the trees. The campground felt like it was geared towards RVs rather than tent campers. The campground itself had a convenience store, laundry facility and the only showers in the whole Big Bend park. It's also nearby the Mexican border which we did visit. It was super convenient. $5/pp to get across the river and then you had options to get a ride in to town but it was only a quarter of a mile walk. BEST. TACOS. AND MARGS EVER!!!. You stop at a trailer to get a visa from border patrol once in Mexico and then stop at a self service terminal when you get back in to Texas. Anyway, back to the campground, I didn't like this campground but it was nice to know that there were plenty of sites available if needed.
