South San Juan Wilderness

A remote wilderness of steep valleys and high peaks in Southern Colorado

South San Juan UndergrowthWild and rugged, the San Juan Mountains of Colorado stretch in an arc over a hundred miles long from southwestern Colorado into northern New Mexico. It is in a remote part of the San Juan range, just to the north of the New Mexico state line that the South San Juan wilderness is found. It is in this place that the San Juan mountains remain yet untouched by man and where the wanderer can find solitude from the crowded avenues of the city.

The South San Juan area is special for its rugged scenery, large expanses of forest, and high altitude trails that offer a sense of remoteness difficult to find elsewhere. High ridges, pinnacles and deep canyons, carved by the headwaters of the San Juan, Conejos, and Blancos rivers characterize the geography of the wilderness. Pristine spruce, fir and ponderosa forest make the South San Juan wilderness a sanctuary for deer, elk, bear, and other wildlife that thrives unmolested by human activity. It comes as no surprise then that it was in this place that the last Colorado grizzly was shot in 1979.

The best backpacking in the state is here, some would argue. In the autumn, the area is popular with hunting parties looking for trophy elk. But outside of the autumn hunting season, solitude can be more readily found here for the soul who is willing to seek it out.

How to Get There

The South San Juan wilderness is located in southern Colorado near the towns of Pagosa Springs, South Fork, and Antonito. The wilderness boundary extends from south of Hwy 160 to just north of Hwy 17. Access to the wilderness is mainly from the north via Hwy 160 or from the east through the town of Antonito.

Visiting the South San Juan Wilderness

For visitors to the South San Juan, it is important to be prepared for a variety of weather conditions that can occur at high altitude. Summers are sunny with frequent afternoon thunderstorms, lightning, and heavy rain. August is the rainiest month, with a unique weather phenomenon called the ‘monsoon’. The San Juan mountains experience a rainy season known as the monsoon season which consists of day after day of torrential rains and overcast skies. The monsoon arrives in late July or early August and can last into the first weeks of September. See my Colorado Backpacking Guide for more information about weather and preparing your trip to the Rockies.

Winters in the San Juans are harsh and it is not uncommon for heavy winter snows to occur, even early in the fall. In many years, the highest recorded snow fall for the state is measured here (as claimed by the Wolf Creek Ski resort just to the north). The high snowfall is due to the geography and location of the southern San Juan mountain range being ideally positioned to catch moisture laden Pacific storms as move from the Four Corners region into southern Colorado.

Conejos Peak is worth the climb not only for the summit views, but for the spectacular scenery found along the way. The Tobacco Lake Trail leads to the summit.

Wilderness Map

When hiking in the backcountry, maps are a required piece of navigation gear. Personally, I like to use National Geographic’s excellent series of Trails Illustrated maps for their durability, accuracy and ease of use. I’ve included a link to the South San Juan wilderness map below.
