Big Bend Ranch State Park, TX: Closed Canyon

Descend into Closed Canyon's slot for a 1.4-mile round-trip trek from Big Bend's scenic River Road toward the Mexican border and the raging Rio Grande.

From the roadside trailhead, this route descends a small igneous rock hill and follows a wash through open scrub typical of the surrounding Chihuahuan Desert. You’ll descend into a deeper draw, turning left toward the canyon entrance—an imposing 100-foot slot—about 250 yards from the road.
Inside the canyon, the path is easy to follow; you’ll hike across smooth rock with bars of small gravel around occasional puddles. As you continue south, the walls narrow and there are deep depressions created by rapidly flowing water. Depending on recent rains the depressions, known locally as tinajas (the Spanish word for jar), may contain fairly deep water and the pools could make scrambling or wading necessary to continue.
After the second tinaja, the canyon begins dropping steeply toward the Rio Grande with larger and larger steps (10, 12, 25, then 50 feet in height) that require rappelling gear to descend. Without the extra gear, plan to turn around about 0.75 miles from the road.
Caution: Check weather forecasts before tackling the hike, steep canyon walls leave no escape routes and flash floods are possible.

Trail Facts

  • Distance: 2.3



Location: 29.328569, -104.03114

The Closed Canyon trailhead is roughly the halfway point on the scenic drive down Ranch Road 170 between Presidio and Terlingua. There is a shaded picnic table and map kiosk here in addition to parking.


Location: 29.326628, -104.032309

Head into the narrow canyon entrance about 250 yards from the road. The canyon is 12-20 feet across and winds occasionally as it rolls southwest toward the Rio Grande.


Location: 29.324514, -104.035592

Continuing into the canyon can be difficult if the water is high in a few deep tinajas. Watch for cactus-covered hand holds and expect some shallow wading if the tinajas are full and you plan to continue.

Without rappelling and climbing equipment, it’s impossible to reach the river at the end of the canyon. Depending on recent weather and reservoir control on the Mexican side of the border, the Rio Grande could also be a raging river. If you do plan to descend the entire way, check river conditions with rangers before your trip.

Shady recesses in the canyon create a hospitable environment for flowers.

First Section

Location: 29.325815, -104.033897

A smooth rock surface lines the bottom of the canyon’s early stretches.
