About Green Ridge

Overview

Green Ridge Campground is located on beautiful Shadow Mountain Reservoir, southwest of Grand Lake in north central Colorado. Visitors enjoy the area for its great boating, fishing and hiking opportunities.

Recreation

Shadow Mountain Lake is part of the Arapaho National Recreation Area. It offers boating, swimming and fishing. Anglers cast for kokanee salmon, as well as rainbow, brown, mackinaw and cutthroat trout. A boat ramp and dock are located within the campground. The Colorado River can also be accessed from the campground. National Fishing Week is held annually the first week of June.

Numerous hiking and horseback riding trails are in the vicinity, including the East Shore Trail (which is part of the Continental Divide National Scenic Trail), Roaring Fork Trail and Monarch Lake Trail.

Facilities

The campground offers 79 non-electric, single-family sites, as well as one double and one triple capacity campsite. A single site may hold up to eight people. Picnic tables, campfire rings and tent pads are provided, as are flush and vault toilets and drinking water. Firewood may be gathered in the forest or purchased from the host.

Natural Features

The campground is situated between the southern shore of Shadow Mountain Lake and the banks of the Colorado River, at an elevation of approximately 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, there is little to no shade available in the campground. Since 2008, 3,000 pine seedlings have been planted to remedy the problem in the future.

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 in the park.
