What to See and Do
Hiking and Biking
Horsethief Mesa Trail
This is a loop trail with biking and hiking paths that are narrow and prone to steep drops and irregularities. There are many natural ramps along the winding loop. The trail has a rollercoaster-like quality as different descents will bring unique jumps and grooves to manage. The back half of the loop becomes more open and flat, making it a good place to wind down and catch your breath.
Length: 9 miles
Intensity: Intermediate
Rio Grande Gorge West Rim Trail
This is a straight, out-and-back trail less than 20 minutes from Horsethief Mesa Trail. It intersects the greater Rio Grande Del Norte National Monument area. It closely follows the gorge's side for its duration, and the path is mostly flat. Vegetation and rock features become sparser the deeper you delve into the mid-size trail.
Length: 3.7 miles
Intensity: Easy
Rift Valley Loop Trail
This is a large loop trail that intersects with all other trails within the area. You can use it as a shortcut to other trails or for a quick exit. Following the loop, the long path remains free of steep drops and difficult inclines in spite of its size. It's a leisurely trail for biking, sightseeing, and hiking.
Length: 10.3 miles
Intensity: Easy
Arsenic Springs and River Trails
This is an out-and-back trail located at a high elevation. It's deep into the park and offers many rocky, mud-slicked ramps for you to enjoy on the descent. It's the most challenging path within the park for mountain biking. The trip up the path, while steep, is broad and is good for hiking and sightseeing; a spring is located at the bottom of the path.
Length: 2.2 miles
Intensity: Difficult
Fishing and Boating
Horsethief Mesa Trail overlooks a river at the bottom of the Rio Grande gorge. It requires a challenging descent to reach, but fishing and swimming are permitted here. Boat access is not permitted from this trail. A short hike away, the Black Valley Hot Springs Trail offers more fishing opportunities with its creek, streams, and springs. The area's eponymous hot springs are open for swimming, too. Another option is the nearby Arsenic Springs Trail, where fishing and boating are also possible at the trail's basin. New Mexico's freshwater sources are home to many species of fish, like bass, trout, and many kinds of salmon. Unique to the area is the Rio Grande cutthroat trout.
Climbing
The gorge on the back half of the loop offers many challenging climbing opportunities. Intermediate and easy climbing challenges are available near the base of the gorge. Horsethief Mesa Trail is a popular access point for climbing activities within the larger park, so it will be crowded. Nearby Arsenic Summit and the Rio Grande Gorge West Rim Trail also have climbing opportunities.
Horseback Riding
Horseback riding is possible on the Horsethief Mesa Trail. The top of the mesa has a lot of open space and sturdy, flat ground. Horses will have plenty of room to run, making it a fun destination for the activity. Nearby Trader's Trail is another wide-open area with flat terrain suitable for horseback riding.
Wildlife Viewing
Horsethief Mesa Trail is home to many chipmunks and squirrels. Small lizards dominate the higher altitudes. The open sky of the mesa will allow you to see many colorful birds like the meadowlark. Large birds of prey, raptors, and owls are also common in the area. Coyotes, small cats, and black bears are found on Horsethief Mesa Trail, though they are shy. Elk and deer are common as well.
