What to do out here.

A1

Hike the Chisos

High country switchbacks to the South Rim, with the whole desert at your feet.

The Chisos are the only mountain range entirely contained within a national park, and the trails climb from desert floor to pine forest in a single morning. The South Rim is the headline, a long, hard loop to a 2,000-foot drop-off, but the Window Trail and Lost Mine are shorter and just as worth it.

Field notes

• Start before dawn from May through September.
• Carry more water than you think, at least a gallon per person.
• Check trail status at the Chisos Basin visitor center.

A2

Paddle the Rio

Float Santa Elena Canyon between 1,500-foot limestone walls.

The Rio Grande carves three major canyons through the park. Santa Elena is the classic: sheer 1,500-foot walls, calm water for most of the year, and one short rapid to keep you honest. Mariscal and Boquillas are longer and quieter. Water levels change everything, so ask before you launch.

Field notes

• Check the river gauge before you go; low water means dragging.
• Permits are required for overnight river trips.
• Spring and early summer have the best flows.

A3

Ride the washes

Gravel and singletrack across the Chihuahuan desert flats.

Outside the park boundary, the desert opens into miles of graded dirt road and rougher singletrack. The riding is dry, fast, and exposed, with views in every direction. Inside the park, bikes stay on paved and dirt roads, not trails, so most of the good riding is on the BLM and ranch roads nearby.

Field notes

• Ride early; there is no shade out here.
• Tubeless tires and a real repair kit are worth it.
• Tell someone your route; cell service is rare.

A4

Run the backcountry

4x4 the old mining roads to springs and ghost towns.

The park is laced with primitive roads that lead to hot springs, ghost towns, and overlooks the paved roads never reach. River Road, Old Ore Road, and the Glenn Springs route are the classics. High clearance and four-wheel drive are not optional out here, and a recovery kit is smart.

Field notes

• Air down for the rough stuff and carry a compressor.
• Some roads need a backcountry permit.
• Never drive off the designated route.

A5

Read the stars

One of the darkest skies in the lower 48. Bring a blanket.

Big Bend is a certified International Dark Sky park, with some of the least light-polluted skies in the continental United States. On a moonless night the Milky Way casts a shadow. You do not need any gear to be amazed, but a telescope or even binoculars open up another layer entirely.

Field notes

• Check the moon phase; a new moon is darkest.
• Use a red light to keep your night vision.
• Give your eyes 20 minutes to adjust.
