Arapaho Bay Campground operates three distinct loops along Lake Granby's shoreline from late May through September, with sites ranging from $29-58 per night. The Forest Service maintains this 84-site facility within Arapaho National Forest, though campers should prepare for washboard dirt roads leading to the entrance.
Each loop offers different camping experiences. Big Rock Loop provides full shade coverage but requires a short drive to reach the water. The Moraine and Roaring Fork loops sit directly on the lake with immediate water access but minimal tree cover. Andi A. notes that "Roaring Fork loop is right next to a natural waterfall which provided wonderful noise while sleeping." Sites accommodate RVs up to 45 feet, though many spaces are compact and better suited for single parties.
The campground serves as a launch point for multiple activities. Kayakers and paddleboarders use the boat ramp to access Lake Granby's calm waters. Monarch Lake sits one mile away, offering an easy hiking loop suitable for families with small children. More challenging options include the Roaring Fork Trail, which climbs 2,000 feet over six miles to reach alpine lakes where backpacking permits allow overnight stays.
Wildlife encounters are common throughout the camping season. Multiple reviewers report moose sightings near campsites, and bear activity requires proper food storage in provided bear boxes. The campground maintains vault toilets and water spigots, though no hand-washing facilities exist at restrooms. Biting flies and mosquitoes persist during summer months.
For campers seeking additional options in the area, campsites near Grand Lake provide alternatives nine miles north, while Big Rock Campground offers a nearby alternative with different amenities.
Description
Overview
The Arapaho Bay Campground is located in the Arapaho National Recreation Area on Lake Granby, southeast of Grand Lake. Visitors enjoy the area for its great boating, fishing and hiking opportunities.
Recreation
Lake Granby is part of the Arapaho National Recreation Area. It offers boating, sailing, swimming and fishing. Anglers cast for kokanee salmon and a variety of trout, including rainbow, brown, mackinaw and cutthroat. National Fishing Week is held the first week of June each year. Numerous hiking and horseback riding trails are located within the Arapaho National Recreation Area, including the Roaring Fork Trail, Monarch Lake Trail and the East Shore Trail (which is part of the Continental Divide National Scenic Trail).
Facilities
The campground offers three loops of single- and double-family sites, a few of which are accessible. Each site is equipped with a picnic table, campfire ring and tent pad. Vault toilets, drinking water and trash collection are provided.
Natural Features
The campground is situated on Arapaho Bay, on the eastern tip of Lake Granby, at an elevation of 8,300 feet. Afternoon thunder showers should be expected during the summer months. Due to the mountain pine beetle infestation and consequent hazardous tree removal, the campground offers little to no shade.
