About

Overview

Cutthroat Bay Group 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.

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 nearby. National Fishing Week is held annually the first week of June.

Numerous hiking, biking 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), AA Barn Loop Trail, Roaring Fork Trail and Monarch Lake Trail.

Facilities

The campground offers two accessible group campsites that accommodate up to 30 people each. Each site is equipped with a picnic shelter, tables, a campfire circle and 12 tent pads.

Vault toilets and drinking water are provided. A volleyball court and horseshoe pits are also available at the campground.

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 provides no natural shade.
