Public land it sits in

On Wilderness Atlas →

This campground sits inside Grand Mesa, Uncompahgre and Gunnison National Forests.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

The campground is set high in the Colorado Rockies at an elevation of 10,200 feet. Summer days are cool and afternoon showers are common. Nights can be chilly. Lake Irwin borders the campground on the east, and the Ruby Mountain Range lies to the west. Vivid wildflowers fill the landscape during July and August. Most campsites are shaded by mature Englemann spruce and subalpine fir trees. The Grand Mesa, Uncompahgre and Gunnison National Forests are located on the western slope of the Rocky Mountains. Together, the three forests cover 2.9 million acres in the central and southern Rocky Mountains, south of the Colorado River and west of the Continental Divide.

Recreation

Mountain biking and hiking are popular activities in this challenging, rugged terrain. Canoeing and fishing are favorite pastimes as well. The lake is usually so full of fish, one can see them rise to the calm surface.
