Big Bend National Park

Log in to track your visit to Big Bend National Park.

Big Bend National Park occupies the remote southwestern corner of Texas, where the Rio Grande carves its sweeping southward arc — the "big bend" that gives the park its name — and three distinct ecosystems collide in spectacular fashion. Covering 800,000 acres, it is one of the largest and least-visited national parks in the lower 48, a place where the Chihuahuan Desert floor rises abruptly into the Chisos Mountains, pine and oak forests cap the high country at 7,800 feet, and canyon walls hundreds of feet tall pinch the Rio Grande into rushing green ribbons. Established in 1944, Big Bend shares more than 100 miles of border with Mexico, and the cultural, ecological, and geological connections across that river are impossible to ignore. The park receives fewer than 500,000 visitors a year — a fraction of Zion or Yellowstone — which means genuine solitude is still achievable. Its designation as an International Dark Sky Park makes it one of the best stargazing destinations in the entire United States, with the Milky Way so bright on moonless nights that it casts faint shadows. Big Bend rewards the patient traveler willing to drive its long empty roads and sit quietly with its extraordinary landscape.

Santa Elena Canyon Trail (1.7 miles round trip) walks into the mouth of a canyon where the Rio Grande squeezes between 1,500-foot vertical walls of Mesa de Anguila on the Mexican side — one of the most dramatic short hikes in America. The Lost Mine Trail (4.8 miles round trip, 1,100 feet gain) in the Chisos Basin is the park's premier mountain hike, climbing through pine forest to a ridgetop with views stretching 200 miles into Mexico on clear days. The South Rim Loop (12–14 miles) is an unforgettable overnight backpacking route along the highest cliffs in the Chisos, requiring a backcountry permit. Hot Springs Historic District offers a short riverside walk to a natural hot spring (105°F) right at the Rio Grande where you can soak with a view of Mexico. River trips through Boquillas Canyon and Mariscal Canyon by canoe or raft are world-class multi-day adventures. Stargazing at the Chisos Basin Visitor Center parking lot after dark, or driving to the Persimmon Gap area, delivers a sky overwhelmed with stars.

Big Bend's biodiversity is staggering for a desert park. Over 450 bird species have been recorded here — more than any other national park — making it a bucket-list destination for birders. The Colima warbler, found nowhere else in the US, breeds in the Chisos high country each spring. Javelinas (collared peccaries) roam the desert in family groups and are commonly seen near the campgrounds. Black bears inhabit the Chisos Mountains and are becoming increasingly common. Mountain lions are present but rarely seen. The endangered Peregrine falcon nests on canyon walls, and the Rio Grande supports rare Rio Grande cichlids, freshwater turtles, and alligator gar.

Entry is $35 per vehicle (valid 7 days). The park's remoteness is real: the nearest full-service gas station outside the park is 100+ miles away, so fill your tank at the Panther Junction or Castolon stations before leaving. Chisos Mountains Lodge is the only in-park lodging; book 13 months in advance for spring and fall. Campgrounds include Chisos Basin (most popular), Rio Grande Village, and Cottonwood — all first-come, first-served or reservable via Recreation.gov. Spring (March–April) and fall (October–November) are the sweet spots; summer can exceed 110°F at lower elevations.

Big Bend is remote by design. The park entrance at Persimmon Gap is 100 miles south of Marathon, TX (the nearest town with services), via US-385. From El Paso, it is 330 miles (about 4.5 hours). From San Antonio, expect 6 hours via US-90. The nearest commercial airports are Midland International (MAF, 230 miles) and El Paso International (ELP, 330 miles). A personal vehicle is essential — there is no public transit.

Download offline maps before you arrive — cell service is nonexistent throughout most of the park. Carry a minimum of one gallon of water per person per day in warm months; dehydration and heat exhaustion are serious risks. The Window Trail in Chisos Basin is spectacular at sunset — time it so you are at the pouroff as the sun drops. Cross into Boquillas del Carmen, the tiny Mexican village across the river, via the official crossing at Boquillas Port of Entry (bring your passport). Bear boxes are required for food storage at backcountry sites.
