South San Juan Wilderness: San Juan

The South San Juan Wilderness encompasses the southeastern extent of the San Juan Mountain Range, including a segment of the Continental Divide. Originally designated as wilderness by Congress in 1980, it is a component of the National Wilderness Preservation System and now maintains 158,790 acres.

Ages of volcanic activity followed by the carving of glaciers left the rough, imposing terrain of the remote South San Juan Wilderness, an area characterized by steep slopes above wide U-shaped valleys cut deeper by eroding streams. You'll find high peaks and cliffs, as well as jagged pinnacles and ragged ridges, making travel difficult. Elevations rise as high as 13,300 feet.

Thirty-two lakes, most of them formed by glacial activity, hold much of the area's moisture and drain into turbulent creeks. The Conejos, San Juan, and Blanco Rivers have their headwaters here. You'll find about 180 miles of trails, and some of the most exemplary backpacking in the state. The Continental Divide crosses the heart of the Wilderness for 42 miles. 

Please always use Leave No Trace techniques to help keep these areas wild, clean, and pristine.
