Cottonwood Campground is a remote, quiet 30-site campground in Big Bend National Park's southwestern corner with direct Rio Grande access, ideal for paddlers and anglers seeking a primitive camping base near Santa Elena Canyon.

The campground offers dry camping only (no hookups or generators), pit toilets, potable water, bear boxes, and picnic tables at each site, with a walk-in group tent site available by reservation.

Note that this remote location has zero cell service, requires advance reservations (up to 14 days), and experiences extreme heat (over 100°F) from mid-March through August, making fall and winter the optimal seasons for visits.
