About Stillwater (colorado)

Overview

Stillwater Campground is located on Lake Granby, six miles southeast of Grand Lake, in north central Colorado. Visitors enjoy the area for its great boating, fishing and hiking opportunities. The necessary Arapaho National Recreation Area pass can now be purchased online (Interagency Age and Access passes are also valid)!

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 on-site. National Fishing Week is held annually the first week of June. Numerous hiking 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), Roaring Fork Trail and Monarch Lake Trail.

Facilities

This campground is the largest one available on the Arapaho and Roosevelt National Forest. It offers 129 sites, 21 of which have electric hookups. Single- and double-family campsites are available and some are accessible. Each site is equipped with a picnic table, campfire ring and tent pad. Parking can accommodate RVs of many sizes; spurs range from 25 to 40 feet in length.

Flush and vault toilets, showers, drinking water and a dump station are provided.

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 has little to no shade.

Nearby Attractions

Rocky Mountain National Park's West Entrance is located north of Grand Lake. With lush valleys and craggy peaks reaching elevations higher than 14,000 feet, visitors are provided opportunities for countless breathtaking experiences and adventures. Scenic driving, hiking, backpacking, fishing, horseback riding and wildlife viewing are popular activities enjoyed by visitors to the park.
