Mule Ears Spring Trail

Overview

A classic Chihuahuan Desert hike with a payoff you can feel: shade, greenery, and water. The Mule Ears Spring Trail leaves from Mule Ears Overlook on Ross Maxwell Scenic Drive and heads toward the twin volcanic dikes that resemble, well, mule ears. It’s an easy–moderate outing most hikers can handle, with broad desert views and a surprising oasis at the turnaround.

Route and What You’ll See

Plan on about 3.8–4.0 miles total out and back to the spring, typically taking around 2 hours. The path undulates over rocky, sandy desert singletrack, crosses a few dry washes, and offers little to no shade until you reach the spring. Expect modest net gain (around 225 feet) but more cumulative up-and-down, which some sources peg much higher because of the rolling terrain. The “ears” themselves are volcanic dikes; along the way you’ll pass volcanic tuff and other igneous features. Near the spring, watch for a ranch-era stone corral—an evocative piece of Big Bend history. The spring area is lush by desert standards, with cottonwoods, ferns, and cattails. Sit quietly and you might spot birds, dragonflies, or even a leopard frog.

If you’re feeling good, continue past the spring to a higher vantage point for a roughly 5.9‑mile round trip, with more elevation gain. The trail also continues toward Smoky Creek if you’re linking routes.

Best Time to Hike

Fall, winter, and early spring are prime—cooler temps make the exposed miles pleasant. Summer heat can be dangerous. Start early to beat the sun and enjoy softer light on the Mule Ears. The overlook lot sees steady turnover because many visitors stop just for the viewpoint; once you’re past the overlook, the trail often feels quiet.

Know Before You Go

Bring plenty of water and strong sun protection—there’s essentially no shade until the spring, and the desert heat is the main difficulty. Do not drink from the spring and don’t disturb this fragile oasis. Pets aren’t allowed on park trails, and no permit is required for day hiking (standard park entry fees apply). Expect some loose rock and minor wash crossings; sturdy footwear helps.
