Big Bend National Park

Big Bend National Park is one of the largest, wildest and most remote national parks in the contiguous United States, sprawling across more than 800,000 acres of far West Texas where the Rio Grande makes its great southward bend along the Mexican border. A land of staggering scale and diversity, the park encompasses three distinct worlds: the vast Chihuahuan Desert, the rugged Chisos Mountains rising green and cool from the desert floor, and the deep, dramatic canyons the Rio Grande has carved through towering limestone walls.

Within its remote expanse, Big Bend shelters extraordinary biodiversity — more bird species than any other national park, along with desert wildlife, mountain forests and the river’s ribbon of life — beneath some of the darkest night skies in North America, a renowned International Dark Sky Park. Visitors hike the Chisos high country, raft or canoe the Rio Grande through Santa Elena and other canyons, explore the desert, soak in hot springs, and marvel at the stars. Vast, wild, and achingly beautiful, Big Bend is a treasured crown jewel of the American Southwest in the heart of West Texas.

Big Bend National Park offers vast, varied recreation — hiking the cool, forested Chisos Mountains (the Window, Lost Mine and South Rim trails) and the desert trails, rafting, canoeing or kayaking the Rio Grande through dramatic canyons like Santa Elena, scenic driving (the Ross Maxwell Scenic Drive), soaking in the riverside hot springs, backpacking the remote backcountry, world-class birding and wildlife watching, and stargazing under some of the darkest skies in America. The combination of desert, mountains, river canyons and dark skies makes Big Bend a premier and unforgettable wilderness destination in West Texas.

Fall through spring is the prime season, when the desert and lower elevations are pleasantly cool — spring brings wildflowers and is popular (book ahead), fall and winter offer mild days and crisp nights, and the high Chisos Mountains stay cooler year-round. Summer is brutally hot in the desert and lowlands (often well over 100°F), though the mountains offer some relief and summer monsoon storms green the desert. The park is busiest at spring break and on holidays. Visit in the cooler months for hiking and the river, and any clear night for the stars.

Big Bend’s remote land carries a deep history — Native peoples lived in and crossed the region for thousands of years, followed by Spanish explorers, ranchers, miners (the ruins of the Mariscal mercury mine remain), and farmers along the river. Recognizing its wild grandeur and biodiversity, the park was established in 1944, protecting the desert, mountains and Rio Grande canyons. Big Bend remains one of the most remote and least-crowded large national parks, preserving the vast Chihuahuan Desert wilderness and the layered human history of the West Texas borderlands.

Big Bend is a geological wonderland, where roughly 500 million years of Earth history are exposed across the desert and mountains. The Chisos Mountains are remnants of ancient volcanism, rising as a cool island above the Chihuahuan Desert basin, while the Rio Grande has carved spectacular canyons — Santa Elena, Mariscal and Boquillas — through uplifted limestone laid down in ancient seas, with walls rising up to 1,500 feet. Faulting, volcanism, sedimentation and the river’s erosion over vast time created the park’s dramatic mountains, desert basins, canyons and rich fossil record, including dinosaurs.

Big Bend is renowned for biodiversity, recording more bird species (over 450) than any other national park, along with the chance to see Mexican black bears (recovered in the Chisos), mountain lions, javelinas, desert mule deer, coyotes, roadrunners and countless reptiles, while the river and mountains add their own wildlife. The meeting of desert, mountains and river creates extraordinary habitat diversity. Big Bend is an outstanding place for wildlife watching and especially birding, including specialties like the Colima warbler found nowhere else in the U.S. but the Chisos Mountains.

Big Bend National Park protects an extraordinarily biodiverse landscape where the Chihuahuan Desert, the sky-island Chisos Mountains, and the Rio Grande riparian corridor meet, creating a remarkable range of habitats and one of the most biologically diverse parks in the country. The cool Chisos forests harbor relict species, the desert teems with specialized life, and the river ribbon sustains lush growth and wildlife. The park is an International Dark Sky Park and Biosphere Reserve. Protecting the desert, the mountains, the river and the dark skies sustains a rare and globally significant southwestern ecosystem.

Big Bend National Park holds a treasured place as one of the great wild landscapes of America and an icon of West Texas, its vast desert, rugged mountains, river canyons and dark skies embodying the remote grandeur of the borderlands. The park’s scale, solitude, biodiversity and beauty, along with its layered history of Native peoples, ranchers and miners and its setting on the Rio Grande border, have made it a beloved and almost mythic destination. Big Bend is a cherished symbol of the wild Southwest and the immense, lonely beauty of far West Texas.

Big Bend National Park is in far West Texas along the Rio Grande and the Mexican border, reached via US-385 from Marathon, State Route 118 from Alpine, or FM-170 from Presidio — a long, remote drive (the park is hours from any city, with the nearest airports in Midland and El Paso). An entrance fee applies. The park offers visitor centers, the Chisos Basin lodge and campground, desert and river campgrounds, scenic drives, trails and river access. Services are limited and distances vast; carry fuel, water and supplies. Check the National Park Service for conditions, reservations and access before visiting.

The National Park Service protects the vast Chihuahuan Desert, the Chisos Mountains, the Rio Grande canyons, the extraordinary biodiversity and the dark skies of Big Bend National Park. Visitors help by carrying and conserving water, staying on trails and roads, protecting wildlife (never feeding animals, especially bears in the Chisos), packing out everything, preserving the dark skies, respecting the international border and river, following backcountry permits, and practicing Leave No Trace. Protecting the desert, the sky-island mountains, the river and the dark skies sustains this rare and globally significant southwestern wilderness.

Big Bend is remote and can be dangerous — carry far more water than you think you need (dehydration and heat are the top hazards, with summer temperatures often well over 100°F), tell someone your plans, and never hike in the heat of a summer day in the desert. Distances are vast and services few; carry fuel, supplies and a spare tire. Watch for flash floods in canyons and washes, venomous snakes, and steep drop-offs on mountain and canyon trails. River trips require skill and permits. Respect the heat, the remoteness, the wildlife and the rugged terrain.

An entrance fee applies. Carry and conserve water; stay on trails and designated roads. Backcountry camping and river trips require permits. Never feed or approach wildlife (bear and mountain-lion country — store food properly). Pets are restricted (not allowed on trails or in the backcountry). Drones are prohibited. Collecting (including fossils and rocks) is prohibited. Respect the international border and river-crossing rules. Pack out all trash; preserve the dark skies. Check the National Park Service for permits, conditions and current rules before visiting.

The gateway towns of Terlingua, Study Butte, Marathon, Alpine and Presidio, the Big Bend Ranch State Park (a vast wild park to the west), the scenic FM-170 River Road, and the Davis Mountains and McDonald Observatory lie within the broader region, with the cities of Midland and El Paso hours away. The Chihuahuan Desert and the Rio Grande borderlands define the region. Big Bend National Park anchors a vast, remote wild region of West Texas, a centerpiece of a desert, mountain and river adventure under some of America’s darkest skies.

Plan ahead for this remote park — carry plenty of water, fuel and supplies, and book the Chisos Basin lodge or campgrounds early. Hike the cool Chisos Mountains (the Window, Lost Mine, or the South Rim for the grandest views), drive the Ross Maxwell Scenic Drive to Santa Elena Canyon, soak in the riverside hot springs, and raft or canoe the Rio Grande canyons. Visit in the cooler months (fall through spring), never hike in summer desert heat, bring binoculars for world-class birding, and stay up for some of the darkest, starriest skies in America.
