Things to do
Hike, bike or ride
The park has 238 miles of multiuse trails for hiking, mountain biking and horseback riding. Outfitters lead tours and rent gear if you want help with the terrain.

Float, fish and hike in the Rio Grande/Rio Bravo area, or drive the scenic Camino del Rio (FM 170). River-use permits come from the visitor centers.
Four-wheel-drive roads
