Thanks for all of the info! In your opinion, where would be the best place for say 10 to 20 rigs to camp, preferably within reasonable walking distance? Understand if you don't have an answer but it would certainly help to have some starting points.
@Chili - I've never really looked at trail sites within the national or state parks there with that large of a group in mind, so don't have a good answer for you. Here's what I do know, though:
A good guy to ask would be Nolan Grogan from Mississippi (wngrog on ExPo) who did some excellent trip reports on both BBNP and BBRSP. Here's a trip report he did on ExPo for a 4 vehicle excursion in Jan 2016:
Big Bend NP & SP. He also did a great
solo trip thru BBNP that may shed some light on potential group sites. Hope it's cool to share links to other sites here.
He may have better info on larger group vehicle camping sites for you, though definitely stop at the ranger stations and visitor centers for permits and more current, detailed, info. Some stations and centers are closed during the summer, as it's too hot and not their busy season.
If you reach out to him, tell him the guy who mentioned buying land down that way for
workshops and base-camp purposes (me), told you about him. His email address is on the front page of his
website.
For traditional camping in BBNP, there is
Chisos Basin Campground (60 total sites, 26 of which are reservable certain times of year). This campground is at 5400ft, so way cooler than the lower desert.
: Chisos Basin CG, from a father/daughter trip years ago:
For more primitive dirt road camping in the national park, there are around ten sites in a variety of locations. Here's the best page I know of with links to each location for details :
Primitive Roadside Camping
If you're staying in the park, check this page for recent
Alerts & Conditions
You already have info on the BBRSP roads, I think. They put out a great
pamphlet on off-roading in the state park, with excellent info on what to prepare for, what to bring, what to expect, etc.
I've looked into getting land down that way for off-grid home purposes, with the idea of opening it up now and then for small overland groups of the size you're talking about, so it can be used as a base camp/workshop location from which to explore surrounding areas. Then I can also guide, be the 2nd vehicle for people who come down solo and want to explore, etc.
Far more popular spot, but check out Santa Elena Canyon when in the national park:
That's Mexico on the left, US on the right, and the little speck at the edge of the shadow along the Rio Grande is my kid, that's how huge the landscape can be out there. Up the right side is a cool, narrow, walking trail that goes up the cliff overlooking Rio Grande.
Be sure, too, to check out the night skies while down there. Big Bend is an
International Dark Sky Place.
You'll be amazed, if you're into star-gazing, at how much more night sky you can see in Big Bend.
Good luck, guys, I'll be watching for trip reports.
