Public land it sits in

On Wilderness Atlas →

Rocky Mountain National Park Wilderness begins about 3.5 miles away, and it is the closest of these.

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 situated on the northern shore of Lake Granby, at an elevation of 8,300 feet. Afternoon thunderstorms should be expected during the summer months. Due to the mountain pine beetle infestation and consequent removal of hazardous trees, the campground provides no natural shade.

Recreation

Lake Granby is part of the Arapaho National Recreation Area. It offers boating, sailing, swimming and fishing. Anglers cast for kokanee salmon and rainbow, brown, mackinaw and cutthroat trout. A boat ramp and dock are located nearby. National Fishing Week is held annually the first week of June. Numerous hiking, biking and horseback riding trails are located within the Arapaho National Recreation Area, including the East Shore Trail (which is part of the Continental Divide National Scenic Trail), AA Barn Loop Trail, Roaring Fork Trail and Monarch Lake Trail.
