Rancherias Loop
Big Bend Ranch State Park (Bofecillos Mountains)
Big Bend Ranch State Park lies between Terlingua and Presidio, with a River District along FM 170 and a remote interior. The Rancherias Loop is its best-known backpacking route. Texas Parks & Wildlife magazine calls it “probably the most popular backpacking route” in the park: a three-day, 19-mile loop with water stops at Casa Reza and Rancherias Springs.
Texas Highways, writing in 2019, describes deep canyons, arroyos and mountainous desert in the Bofecillos Mountains, on a trail that is “faint in parts, though marked with cairns.”
The hike
The loop links two trailheads, East and West Rancherias. Trip reports on Big Bend Chat from 2020 and 2025 say most hikers go counterclockwise from the East trailhead, and a November 2025 report finished with a roughly 3-mile road walk between the two trailheads. That hiker warned of a blind curve near the East trailhead.
Day one is the hardest navigation. The November 2025 report, by Sarahswa, describes soft sand in the first wash, steep rocky sections, overgrown trail and easy-to-lose cairns over about 8 miles to Casa Reza, where Ojo de Leon spring flows below an old ranch outpost. She allowed at least 6 hours for that stretch. A 2020 poster, neodprather, warned that the first day has “one treacherous and two dangerous sections.” A February 2025 report said rangers had recently done trail maintenance at the east and west ends.
Day two follows a road section, then trail past Rancherias Spring and up onto Guale Mesa. Texas Highways says Casa Reza and Rancherias Springs are separated by a seven- to eight-hour hike. Rancherias Spring has been unreliable in recent reports: dry in October 2024, and in November 2025 Sarahswa wrote that “You probably won’t find water at Rancherías Spring.” Another poster said you may need to search well down the drainage for pools.
Day three is a gentler descent across the mesas to the West trailhead. Sarahswa cached a gallon of water there before starting.
TPW magazine asks hikers not to enter Casa Reza, which it calls “unsafe and historically important”; most people camp across the stream from the cottonwoods. A ranger told the Texas Highways writer, “Not a lot of people do this hike, so you’ll probably be out there alone,” though she met a dozen hikers at Casa Reza.
Next door in Big Bend National Park, the Outer Mountain Loop is a longer desert-and-mountain loop.
Tips
- Get your permit in person at Barton Warnock Visitor Center (east) or Fort Leaton (west).
- Plan water around Ojo de Leon, and assume Rancherias Spring may be dry. Treat everything.
- Carry navigation backups: a paper map, an offline map and a satellite messenger, as recent hikers advise.
- Watch daylight. A 2020 ranger post warned against hiking in the dark on short winter days.
- Expect wind and cold fronts in fall and winter; a 2025 hiker’s tent stakes pulled out overnight.
Camping
There are no designated campsites in the backcountry zone, according to TPWD; you choose your own spot. Camp at least a quarter mile from any other campsite, 300 feet from water sources and from prehistoric or historic cultural sites, and three-quarters of a mile from trailheads or roads. Sites hold up to six people. The maximum stay is 14 nights total and seven consecutive days in any one backcountry zone. Ground fires and open fires are prohibited; containerized fuel stoves are allowed. Use the cathole method and pack out all trash. There is no water and no restroom. A permit is required and is issued in person daily at either entrance.
Inside Intel: In a December 2020 Big Bend Chat thread, a park ranger posting as Ranger Tim advised crossing the creek at Casa Reza at the trail sign, following cairns to the flattest area, and camping on the higher terrace about 200 to 300 feet from the spring, not in the structures (rodents and bats) and not right by the spring, which animals use at night. On the far side of the loop, Sarahswa wrote in November 2025 that she camped about a mile onto the mesa and that going about 1.5 miles would have given “a much better view.”
