San Isabel National Forest
San Isabel National Forest is located in central Colorado. The forest contains 19 of the state's 53 fourteeners, peaks over 14,000 feet (4,267 m) high, including Mount Elbert, the highest point in Colorado. It is one of eleven national forests in the state of Colorado and contains the Sawatch Range, the Collegiate Peaks, and Sangre de Cristo Range.
It has a total area of 1,120,233 acres (1,750.364 sq mi; 4,533.42 km2) spread out over parts of eleven counties in central Colorado. In descending order of land area it is located in Chaffee, Custer, Lake, Huerfano, Fremont, Pueblo, Saguache, Las Animas, Park, Costilla, and Summit counties. San Isabel National Forest is co-managed by the Forest Service together with Pike National Forest, Cimarron National Grassland, and Comanche National Grassland from offices in Pueblo.
There are local ranger district offices located in Cañon City, Leadville, and Salida.
San Isabel National Forest occupies a particular place in the imagination of American public lands. As a Park Unit in Colorado, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.
The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
