Franklin Mountains State Park: El Paso's Desert Backbone

The largest urban park in the nation sits right in El Paso's backyard. Trails, wildlife, and sunset views over two countries from the Franklin Mountains.

Franklin Mountains State Park covers roughly 27,000 acres and runs north-to-south right through the middle of El Paso, making it the largest urban state park in the United States. The range is the southernmost tip of the Rocky Mountains, and its granite ridgeline defines the city's skyline the way the ocean defines a coastal town.

What makes the park unusual is its accessibility. You do not drive hours to reach it — the Ron Coleman Trailhead sits minutes from a residential West Side neighborhood, and the Tom Mays Unit entrance opens directly off Transmountain Road. A homeowner can be on a trail within twenty minutes of leaving their driveway.

Trails for every level

The park has more than 100 miles of trails ranging from flat desert walks to serious scrambles. The Ron Coleman Trail is the best-known challenge — a steep, exposed climb to a ridgeline that delivers panoramic views of El Paso, Juárez, and New Mexico on a clear day. Bring more water than you think you need; the trail offers zero shade.

For families and casual hikers, the Tom Mays Unit offers shorter, gentler loops like the Aztec Caves Trail, a moderate 1.2-mile round trip that ends at a small rock shelter. The Cottonwood Spring Trail is another good entry point, winding through a wash that actually has water after a monsoon rain.

Mountain bikers will find some of the best desert riding in Texas here, with technical single-track along the foothills. The park permits biking on designated trails only, so check the map at the visitor center before you ride.

Wildlife and desert ecology

The Franklins are home to mule deer, coyotes, the occasional mountain lion, and one of the northernmost populations of Mexican poppies in the country. After a wet winter, the poppy fields on the east slope of the mountains put on one of the most photographed wildflower blooms in the Southwest.

Birdwatchers come for the raptors. Red-tailed hawks and golden eagles ride the thermals along the ridgeline, and the park is a stopover for migratory species crossing the desert. Early morning is the best time to see wildlife before the heat drives everything into the shade.

Planning your visit

The park is open year-round, but summer hiking requires real planning. Trailhead temperatures routinely exceed 100 degrees from June through August, and the park closes certain trails during extreme heat warnings. The best hiking seasons are October through April, when daytime highs are comfortable and the light is at its best.

Entry is a few dollars per adult, and an annual Texas State Parks Pass covers it. Carry a minimum of one gallon of water per person for any trail, wear closed-toe shoes with grip — the granite is slick even when dry — and let someone know which trail you are on. Cell service is unreliable on the back side of the range.
