The Arapaho National Recreation Area (ANRA) in Grand County provides access to Lake Granby and four other major reservoirs with five boat launches, six developed campgrounds (474 camping spaces), and seven picnic areas.

A recreation pass is required for day-use access, and most facilities open in late May weather permitting. The area offers 28 miles of hiking trails and is managed by the Sulphur Ranger District of the U. S. Forest Service.
