Stayed at Grassy Bank (this is not an “interior primitive site”)off and on over a three weeks period in mid to late Feb. 2021. There are 17 designated sites and several dispersed. All numbered sites are large, offer moderate to total privacy, and all have cabanas, picnic tables, and fire rings. #15 is the only camp site directly on the River. Síť there in total privacy and watch canoers maneuver the little rapids, turtles sunning on River rocks, birds and ducks coming and going and a few hundred feet across in Mexico see three horses and a donkey grazing or javelinas coming to drink at the river’s edge. It’s paradise. There’s a canoe launch or go tubing or take a dip. There are two separate but adjacent very clean pít toilets and plenty of open space to walk the dog.

Cost is $12 pěr day plus $5 park entry fee which unfortunately has to be paid every day you camp. There is no cell service or WiFi. Closest access is seven miles away in Lajitas at the market. The woman Ranger who manages the Bartoň Warnock Center during weekdays where you register should not be dealing with the Public. There’s water and a dump station at the Center.
