Yes, you can camp in Guadalupe Mountains National Park. The park offers two developed campgrounds: Pine Springs Campground and Dog Canyon Campground. Both campgrounds are available on a first-come, first-served basis, and they offer tent and RV camping options. Additionally, the park has backcountry camping available for those who prefer a more primitive and remote experience. To camp in the backcountry, you will need a backcountry use permit, which you can obtain at the Pine Springs Visitor Center or Dog Canyon Ranger Station.
