Since discovering Big Bend a few years back we have stayed there several times and it has become our favorite park. The three campgrounds are each unique and have their own appeals. It is remote and one should plan supplies accordingly. While we have not off-roaded there but we have hiked and paddled extensively. Be sure to carry plenty of water when hiking. To us though, the great attraction is the paddling. There is nothing greater than class 1 but some of the canyon vistas are spectacular. It does take some creativity in terms of shuttling but we have not had any problems. A note about the border. Many are worried about drug smugglers etc, but as noted this area is REMOTE and pretty quiet. In perhaps 15-20 miles of paddling on the Rio Grande at various times we have seen zero issues. We have not had any cell phone connection (except climbing on the road out of cottonwood) but the store at rio grande village has free wifi. We have solar so power is not a problem, but be aware the campground at cottonwood does not allow gensets.
