Consisting of miles of pristine Texas gravel, Old Maverick Road winds its way south from Maverick Junction towards Santa Elena Canyon and the rivers of the Rio Grande. Shade is in short supply between the park entrance and canyon, so plan accordingly and pack plenty of water. There are no facilities at either end, besides toilets on the south end, but there are primitive campsites along the way—just make sure to reserve far in advance. Spots are limited and they fill up quickly. Old Maverick Road is also a popular 4x4 route, so expect light traffic during high-visitation times of year.
