Paddling in Rio Grande Wild and Scenic River

The Rio Grande Wild and Scenic River runs along the Texas-Mexico border through the Chihuahuan Desert, cutting through a succession of deep limestone canyons that define some of the most remote paddling terrain in the lower 48.

Administered alongside Big Bend National Park, this stretch of river is not a day-trip destination you stumble into — getting here means long drives across open desert, and once you're on the water, you're genuinely far from help. The canyons are the anchors.

Santa Elena Canyon is the most accessible entry point, a popular day or overnight float with striking walls and easy put-in logistics.

Mariscal Canyon runs about 10 miles — the shortest of the main canyons — and delivers more technical water alongside the scenery; plan for one to two days.

Boquillas Canyon stretches 33 miles and suits paddlers with less river experience, running two to three days at a comfortable pace.

Hot Springs Canyon and the adjacent San Vicente stretch offer a quieter, mellower day or overnight option that sees far less traffic.

Then there are the Lower Canyons — a 5- to 10-day wilderness commitment through open desert and deep canyon country, with mostly flatwater and current punctuated by Class II rapids. Fewer than 300 paddlers run the full Lower Canyons in a typical year.

Spring is the primary season, with March drawing the bulk of river traffic. Water levels vary significantly and shape what's runnable and how technical the rapids read. The permit system here matters.

A National Park Service backcountry use permit is required before any watercraft is placed on the Rio Grande within Big Bend National Park, and for overnight trips on the Wild and Scenic River downstream from the park — day-use inner tubes are the only exception.

USCG-approved PFDs are required for every person on the water; in Santa Elena, Mariscal, Boquillas, and the Lower Canyons, Type I, III, or V PFDs are mandatory, and they must be worn in Class II or greater whitewater.

Private group sizes are capped at 20 people on the Boquillas Canyon and Lower Canyons sections. Commercial operators must hold a Commercial Use Authorization. Check with the park for current permit requirements before you go.

The border context is real and specific: Mexican waters are part of this river corridor, and possession of firearms or ammunition is a felony in Mexico, including on the Mexican side of the river.

Pack-it-out rules are strictly enforced, and no pets are allowed in the backcountry. This is a place that asks something of you before it gives anything back — and what it gives back is considerable.
