Fishing and swimming opportunities on Lake Granby make Arapaho Bay Campground a hub for water-focused camping in the Arapaho National Forest. The campground divides into three distinct loops—Big Rock, Moraine, and Roaring Fork—each with its own entrance and pay station, creating separate camping experiences within the same facility.
The Roaring Fork and Moraine loops sit directly on the lake with minimal shade but offer immediate water access. Mary S. notes that sites 70, 72, and 73 "are out at the end of Roaring Fork with beautiful views of the lake and mountains as well as a sandy beach." The Big Rock loop provides full shade coverage but requires a short drive to reach the water. Michael J. confirms that "facilities were clean, and at least our loop had good trees for privacy."
Campers launch kayaks and paddleboards from the boat ramp when open, while the calm lake conditions suit various watercraft. Wildlife encounters add excitement—moose frequently visit campsites, and bears appear regularly throughout the area. The Roaring Fork Trail begins at the campground entrance, climbing 2,000 feet over six miles to reach Upper Lake or Watanga Lake. Monarch Lake, located one mile away, offers an easier four-mile loop trail that families with small children can manage.
Sites accommodate varying RV sizes, though many reviewers describe them as compact for sharing between multiple parties. Bear boxes come standard at each site, and vault toilets serve the campground. The gravel access road receives regular maintenance but can develop washboard conditions. Andi A. warns that "the drive in is not the best. A lot of washboard dirt road."
Reservations through Recreation.gov secure most sites, though some first-come, first-served options remain available. The campground fills consistently during summer months, and campers exploring places to camp near Grand Lake will find this location serves groups prioritizing lake access and hiking trail proximity over site privacy.
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.
