Pecos Wilderness

Featuring narrow canyons, sprawling mesas, and dense canyons, the Pecos Wilderness is a large federally protected area located in the north-central part of the US state of New Mexico. The wilderness contains 32 named mountains, the highest and most prominent of which is Truchas Peak (13,091 ft/3,990 m).

Pecos Wilderness, New Mexico


Sometimes called the Northern Pecos Wilderness, the Pecos Wilderness is a federally protected wilderness area located in the north-central part of the US state of New Mexico.

It contains a total area of 223,667 acres (90,514 ha) in Santa Fe County just outside the city of Santa Fe. This makes it the second largest wilderness in New Mexico after the Gila Wilderness in the Gila National Forest.

The Pecos Wilderness is located on US Forest Service land and it is co-managed by both the Carson and Santa Fe national forests. It is situated within the Espanola Ranger District of Santa Fe National Forest and the Camino Real Ranger District of Carson National Forest.

Furthermore, the Pecos Wilderness is located in close proximity to a large number of other areas of protected land. In particular, the wilderness is located to the south of a large swath of land in the Carson National Forest and within driving distance of the Wheeler Peak, Cruces Basin, Latir Peak, and Columbine-Hondo wilderness areas.

It is also located to the east of the rest of the Santa Fe National Forest as well as the Valles Caldera National Preserve. Finally, the wilderness is situated to the east of the Las Vegas National Wildlife Refuge and the Sabinoso Wilderness.

Within the Pecos Wilderness, the landscape is dominated by staggering peaks of the Sangre de Cristo Range as well as deep valleys that separate some of the region’s largest mesas. The Pecos River, which is a National Wild and Scenic River and a tributary of the Rio Grande, also flows through the wilderness.

Additionally, the wilderness contains fifteen lakes and more than 150 miles (240 km) of rivers and streams. This makes it the perfect habitat for a range of different aquatic species, including various types of trout.


The mountains within the Pecos Wilderness are a part of the Sangre de Cristo Range, which is a subrange of the greater Southern Rocky Mountains.

As a subrange of the Rockies, the Sangre de Cristo Range started to form during a mountain building event known as the Laramide orogeny. This mountain building event, alongside the Sevier orogeny, was responsible for creating a large number of mountain ranges in the western part of the US and Canada.

Truchas Peak

Within the range, there are a number of different rock types, including Precambrian metamorphic rocks and substantially younger sedimentary rocks. Some of the many rocks found in and around the Pecos Wilderness include gneisses, granites, schists, quartzites, and amphibolites.

Major peaks in the Pecos Wilderness include Truchas Peak, North Truchas Peak, Chimayosos Peak, Jicarita Peak, Sheepshead Peak, Santa Fe Baldy, Lake Peak, Hermit Peak, and Sierra Mosca.


The Pecos Wilderness is particularly well known for its diversity of ecosystems and the superb array of flora and fauna that can be found within its borders.

At low to mid elevations in the wilderness, the landscape is mostly dominated by dense forests. These forests are home to a slew of different tree species including Engelmann spruce, limber pine, bristlecone pine, white fir, Douglas fir, corkbark fir, ponderosa pine, and aspen. Wildflower meadows are also common at higher elevations.

As far as wildlife goes, the Pecos Wilderness is a true haven for a plethora of species. Some of the many mammals found in the wilderness include black bears, elk, mule deer, coyotes, bobcats, mountain lions, and beavers. The wilderness is also home to one of the largest herds of Rocky Mountain bighorn sheep in the region.

Furthermore, the Pecos Wilderness’ many waterways make it a particularly great place to find a number of different fish species. Some of the most notable species of fish in the wilderness include brown trout, rainbow trout, and the elusive Rio Grande cutthroat trout.

Human History

Humans have lived in the area in and around what is now the Pecos Wilderness for countless generations. The land is the traditional territory of many Indigenous peoples, including the Jicarilla Apache Nation and many Puebloans, including the Ohkay Owingeh Pueblo, Picuris Pueblo, Santa Clara Pueblo, San Ildefonso Pueblo, Pueblo of Pojoaque, Tesuque Pueblo, and Nambe Pueblo, among others.

Peoples of European descent first came to the region in the sixteenth century. Spanish conquistador Juan de Oñate y Salazar established the colony of Santa Fe de Nuevo México in the region 1598.

However, Oñate was banished from the region for use of extreme force against Indigenous peoples in the Acoma Massacre. While cruelty against Indigenous peoples was common in the Spanish Empire, this was one of the few times that a conquistador faced punishment for their actions.

The city of Santa Fe, which is located just to the southwest of the Pecos Wilderness, was established in 1607 by Pedro de Peralta. In 1680, the Pueblo Revolt caused many of the Spanish colonizers to leave the region, though they returned not long afterward.

For nearly 150 years afterward, the region was administered by the Spanish as part of New Spain. It became the territory of Mexico in the 1820s after the Mexican War of Independence and it was later ceded to the United States as part of the Treaty of Guadalupe Hidalgo after the Mexican-American War in 1848.

During the 1870s, the region became a popular destination for gold and mineral prospectors. The Pecos River was an exciting place for gold prospectors as it was the source of a decent amount of placer gold.

The Santa Fe National Forest was established in 1915 after the merger of the former Pecos National Forest and Jemez National Forest. Half a century later, the Pecos Wilderness was established as part of the Wilderness Act of 1964.

Main Hiking Areas

The Pecos Wilderness is home to more than 400 miles (643 km) of hiking trails. Here are some of the top hikes to consider during your next visit to the wilderness:

Windsor Trail

The Winsor Trail (more formally known as the Winsor National Recreation Trail or Trail #254) is a 9 mile (14.4 km) long hiking trail that’s often considered to be one of the premier treks in the Pecos wilderness.

This trail departs from the Winsor Trailhead and climbs steadily upward to Carpenter Ridge. From there, it meets up with the Skyline Trail. If you continue down the Skyline Trail for a short distance until the Winsor Trail veers to the south, you’ll eventually arrive at Spirit Lake, which offers superb views of the wilderness area.

Truchas Peaks

The Truchas Peaks massif, which contains Truchas Peak, Middle Truchas Peak, West Truchas Peak, and North Truchas Peak, is one of the crown jewels of hiking in the Pecos Wilderness. This massif is accessible via a number of hiking routes, though some of the region’s trails are difficult to follow.

Although there is a way to approach the massif from the west, this is generally not recommended due to vandalism issues at some of the trailheads, including Quemado Creek. Other approaches include the southern approach from Jack’s Creek Campground and the northern approach from Santa Barbara Campground.

Again, keep in mind that the Truchas Peaks massif is seldom visited except by keen peak baggers. So, solid route-finding skills are a must if you plan to trek to the summit of any of the Truchas Peaks.

Pecos Baldy Lake

The Pecos Baldy Lake Trail is one of the most popular in the wilderness area. This 7.6 mile (12.2 km) hike to Pecos Baldy provides stunning vistas and a chance to see some of the region’s best wildflower meadows.

The trail starts at Jack’s Creek Campground and then travels steadily upward into the alpine. Keep in mind that snow is usually present on this trail until mid-summer. Eventually, you’ll arrive at the lake itself, where you can go for a swim or simply keep an eye out for bighorn sheep. Also do note that camping is not allowed in the lake basin, but there are camping spots nearby.
