1. Backcountry/Boondocking sites (Big Bend National Park)
Big Bend is a huge national park, with several good campsites for trailers, included our shady site in Rio Grande that provided some shelter from the 104 degree heat. But one special thing in Big Bend we have yet to see at another National Park are designated boondock sites for RVs. Essentially, these are backcountry camping sites that are accessible by car (“Primitive Roadside Camping”). This means there are a dozen or so scenic spots scattered around this huge park where you can pull your trailer off-road — and provided you make it down the gravel side roads with trailer intact — you find yourself completely alone under the shadows of the Chiso Mountains.
