Welcome to the Arapaho National Recreation Area (ANRA) - a 35,000 acre scenic water wonderland in the upper reaches of the Colorado River Valley. The ANRA was established by Congress in 1978 and contains five major reservoirs: Lake Granby, Shadow Mountain Lake, Monarch Lake, Willow Creek Reservoir and Meadow Creek Reservoir. Grand Lake, adjacent to the ANRA, with its deep, clear blue waters, is the largest natural lake in Colorado. Together, the lakes and reservoirs are often referred to as the "Great Lakes of Colorado."
The ANRA is a world-class place to boat, camp, hike, fish, ice fish, snowmobile, view wildlife, horseback ride and hold events.
An ANRA vehicle pass is required for day. Learn more about how to purchase a pass and where it is required.

An ANRA vehicle pass is required in addition to campground fees for campers. Learn more about ANRA fees.
Dispersed camping is allowed near Meadow Creek Reservoir, along some of the eastern shore of Lake Granby (Map, pdf 4 MB) and along other roads within the recreation area identified for dispersed camping on the Sulphur Ranger District Motor Vehicle Use Map.
Fishing is available on each of the lakes and on public land along creeks and rivers within the ANRA. Lake Granby is known for its kokanee salmon and trophy lake trout. Shadow Mountain Reservoir is stocked with brown and other trout species. Fly fishing opportunities are available along the Colorado River and other nearby creeks. Fishing licenses are required per State of Colorado regulations and seasonal regulations exist on the Colorado River below Shadow Mountain Reservoir Dam.
The Monarch Lake and Junco Lake trailheads within the ANRA are two of the primary entry points to the most popular wilderness area in the National Forest System – the spectacular Indian Peaks Wilderness.
The easy to moderate, four-mile circuit around Monarch Lake offers views up to the valleys and high points of the Indian Peaks Wilderness and is one of the area’s most popular hikes.
The Shadow Mountain Dam Trailhead, accessed near the Green Ridge Campground, offers access to trails into Rocky Mountain National Park and along the Colorado River. (Please note: no dogs are allowed on National Park trails.)
The Continental Divide Trail crosses the ANRA east of Lake Granby.
The AA Barn, a historic, rustic barn on the banks of the rushing Colorado River, is a popular location for weddings, community and corporate events. It is available by reservation from June through September.
The Cutthroat Group Campsite has shelters and may also be reserved for events.
Bird lovers enjoy watching the many osprey in the area. Visitors can watch for them hovering over the water then plunging feet-first for fish, and for the body-parallel method osprey use to carry their prey (versus the perpendicular method eagles use to carry fish). There is an osprey viewing platform and parking for it near the Green Mountain Campground, at the gated end of County Road 66.
Bird watchers flock to Pine Beach to spy many different species of waterfowl and shorebirds.
Other types of wildlife that may be seen in the ANRA include birds like the Stellar's Jay, raven, western bluebird, ptarmigan, and mountain chickadee, and mammals including antelope, moose, deer, elk, bobcats, pine martens, mountain lions, squirrels, black bears and pika.
Never feed or approach wildlife. Keep a clean camp in order to ward off bears. Be aware that moose can become aggressive and may be a bigger threat than bears, particularly around dogs. More outdoor safety tips are available at the following link.
