We love Wild Camping (aka Boondocking) but before our trip to Big Bend, we had never heard of backcountry RV camping in a national park. So naturally we had to check it out and this is the awesomeness of what we found: best camping big bend national park

Almost Free Camping

A measly $10 permit gets you up to 14 days of camping! I call this almost free because anything under $10 a day is cheap much less for two weeks! There are at least 3 areas that are RV friendly for camping: Hannold Draw, Government Spring (we stayed here), and Croton Spring (and here). However, generator use is strictly prohibited (this is where solar comes in handy).
