Alt Text Map of Big Bend National Park in Texas. Outlined in a shade of faint green, the park is roughly oval with stepped borders and two short arms reaching to the northwest from the top and left edges. Surrounding terrain is shown in beige for the US or darker tan for Mexico, and solid red, gray, or black double dashed lines create a web of roads in and around the park. Extended Description The southern perimeter of the park has five visitor centers: Persimmon Gap Visitor Center on the northern tip, two near its center, the fourth on its southeast edge, and the fifth on the southwest edge. This description will begin with the Persimmon Gap Visitor Center and work first down to the center of the map, then head the east, and finally finish in the west, following the routes that connect the visitor centers to the perimeter of the park. Coming in from the north, US Route 385 terminates at the northern tip of the park and from here becomes a park road that heads south past an entrance station and Persimmon Gap Visitor Center, which is closed in summer and has a picnic area and ranger station. The road continues south past the Dog Canyon Trail; unpaved Terlingua Ranch Road, which heads west out of the park; Nine Point Draw, which has a primitive backcountry roadside campsite; unpaved Dagger Flat Auto Trail; Fossil Bone Exhibit, which has a picnic area and self-guiding trail; and Hannold Draw, with a primitive campsite, before arriving at Panther Junction Visitor Center, which houses the Park Headquarters. This site is at an elevation of 3,750 feet (1,143 meters) and has a ranger station, self-guiding trail, and Wi-Fi. From here, another park road, which travels generally east-to-west and bisect the park in two, travels southeast past a spur leading to two primitive campsites at K-Bar; unpaved Glen Spring Road; Dugout Wells, which has a picnic area and self-guiding trail; unpaved River Road East, which heads south and parallels the Rio Grande; unpaved Old Ore Road, which heads back north; a tunnel; and Rio Grande Overlook before finally arriving at Rio Grande Village. The Visitor Center here is at an elevation of 1,850 feet (564 meters) and is closed in summer. The site has a store that is open all year as well as a picnic area, self-guiding trail, campground, campground with full RV hookups, gas station, ranger station, Wi-Fi, and RV dump station. Returning momentarily to Old Ore Road, eleven primitive campsites (backcountry-use permit required) are spaced along its length as it travels north to link up with Dagger Flat Road. From the park road and moving up, sites include Candelilla, Campe de Leon, Ernst Tinaja, La Noria, Ernst Basin, Willow Tank, Telephone Canyon, Roys Peak Vista, and McKinney Spring. Back at Rio Grande Village, features along the southern rim of the park headed east are a Port of Entry, which has customs, across from Boquillas del Carmen in Mexico; Boquillas Canyon Overlook; One Terminal Trail; Marufo Vega Trail; Boquillas Canyon Trail; and Boquillas Canyon. Continuing west along the southern border from Rio Grande Village are Daniels Ranch, which has a picnic area; Hot Springs, which has a picnic area and self-guiding trail; Gravel Pit, with three primitive campsites; and La Clocha, with two more primitive campsites. Shifting back north to Panther Junction Visitor Center, a park road travels west from here to a site with a store and gas station, then reaches Chisos Mountains Basin Junction, where Chisos Basin Road breaks off and heads south. A note in red text here reads, “not recommended for trailers longer than 20 feet and RVs over 24 feet due to sharp curves and steep grades.” This road ends at Chisos Basin, which has an RV dump station and campground. Also found here are a visitor center and Chisos Mountains Lodge, which together have Wi-Fi, a self-guiding trail, store, restaurant, lodging and food, picnic area, and ranger station. Mountain peaks near here include Casa Grande with an elevation of 7,325 feet (2,233 meters), Lost Mine Peak at 7,750 feet (2,301 meters), Emory Peak at 7,825 feet (2,385 meters), and The Window at 4,600 feet (1,500 meters). Trails in this area include Lost Mine Trail and a dense network of unlabeled trails south of the lodge that connect to a loop of trails formed by Juniper Canyon Trail to the east; Dodson Trail (Outer Mountain Loop) to the south; and an unnamed trail extending to Homer Wilson Ranch in the west. This area around Chisos Basin boxed in with gray and a note reads, “See detail map.” Back on the main park road, the route continues west from Chisos Mountains Basin Junction, first passing Grapevine Hills Road, which branches north to access five primitive campsites and Balanced Rock. Additional spurs are passed that lead to Paint Gap and Paint Gap Hills with four primitive campsites; and Croton Spring, which has two primitive campsites, before the road reaches an intersection labeled Castolon/Santa Elena Junction. Ross Maxwell Scenic Drive branches south off the main road at Castolon/Santa Elena Junction and passes Sam Nail Ranch, Sotol Vista near Homer Wilson Ranch, Burro Mesa Pouroff, the eastern terminus of Chimneys Trail, Mule Ears View Point, and Tuff Canyon before arriving at the fifth and final visitor center at Castalon, which is closed in summer. This site has a store that is open all year along with a picnic area, store, and ranger station. The park road continues west to pass Cottonwood, which has a campground; Dorgan House Trail; Santa Elena River Access with raft and canoe take-out and a picnic area; Santa Elena Canyon Overlook; and Santa Elena Canyon Trail at the road’s western terminus. Back on the main road, the route continues west to Maverick Junction and an entrance station there, then continues beyond the park boundary as State Route 118. Old Maverick Road, a primitive road, travels south from Maverick Junction to lead to a primitive campsite at Rattlesnake Mountain; the western terminus of Chimneys Trail; Luna’s Jacal; and a short spur leading to more primitive campsites at Ocotillo Grove and Terlingua Abajo. Old Maverick Road ends at an intersection with Ross Maxwell Scenic Drive near the Santa Elena Canyon Overlook. Santa Elena Canyon runs along the southwestern edge of the park. Just west of this arm of the park is the town of Ljitas, which has a store, restaurant, lodging and food, campground with full RV hookups, and Barton Warnock Museum Environmental Education Center (Big Bend Ranch State Park). Primitive roads run east from the Castolon visitor center to create a network with primitive campsites along the Rio Grande River at the southern park border. Primitive campsites in the southcentral park along the Rio Grande River, from west to east, include Buenos Aires, Black Dike, Gauging Station, Johnson Ranch, Loop Camp, Talley, Solis, La Clocha (2 sites), and Gravel Pit (3 sites). Beyond park boundaries are Black Gap Wildlife Management Area in the upper right corner of the map; the town of Study Butte/Terlingua, which has a store, campground, campground with full RV hookups, restaurant, lodging and food, and gas station, and, in Mexico, Maderas del Carmen Protected Park and Ocampo Protected Area in the lower right and Santa Elena Canyon Protected Area in the lower left. County Road 170 branches off State Route 118 just after Study Butte to reach Terlingua Ghost Town (Historic District), which has a store, campground, restaurant, and lodging and food. State Route 118 continues to Lajitas and the Barton Warnock Museum, which has a store, restaurant, lodging, and campground with full RV hookups. Inset Map A detail map of Chisos Basin is to the left of the main map. Chisos Basin Road winds from the top right corner south and then west across the map to reach the Visitor Center.
