About this campground
Perched at 8,000 feet in the shadow of Green Mountain Reservoir, McDonald Flats Campground offers adventurers a genuine high-country experience. This intimate campground provides the essentials for those seeking solitude and sweeping mountain vistas. Each site comes equipped with a table and grill for memorable outdoor meals, while vault toilets serve the grounds. Though there's no potable water on-site, a convenient hand-pump spigot allows campers to fill their containers. The exposed setting means you'll trade shade for spectacular, unobstructed views of the surrounding peaks and shimmering reservoir below.
McDonald Flats Campground offers a simple camping experience with 12 combined sites catering to both tents and small vehicles. It is not designed for RVs or equestrian camping. Group camping and glamping options are also absent.
Weather and SeasonsAt 8,000 feet, McDonald Flats experiences the full drama of mountain weather. Summer brings refreshingly cool days perfect for escaping valley heat, with crisp mornings giving way to pleasant afternoons under expansive blue skies. As autumn approaches, temperatures begin their descent, and winter transforms the landscape into a frozen wonderland where temperatures regularly plunge below freezing. Savvy campers target those glorious summer weeks when clear skies dominate and moderate temperatures create ideal conditions for stargazing and sunrise watching over the reservoir.
ElevationAt 8,000 feet above sea level, McDonald Flats sits in that sweet spot where the air is crisp, the views are endless, and the night sky seems close enough to touch. This elevation gifts campers with naturally cool temperatures that turn hot summer days into comfortable adventures and transforms evenings into jacket-weather gatherings around the campfire. From this lofty perch, panoramic vistas stretch in every direction, offering front-row seats to Colorado's spectacular high-country theater.
Natural Features and SceneryMcDonald Flats embraces its wide-open character, where knee-high sagebrush creates a tapestry of silver-green across the landscape. While this low-growing vegetation means minimal privacy between sites, it also ensures nothing blocks your view of the stunning surroundings. Select campsites command breathtaking vistas of Green Mountain Reservoir, its waters reflecting the sky like a massive mirror, while the surrounding peaks frame the horizon in dramatic fashion. This is camping for those who prefer their nature unfiltered and their sunsets unobstructed.
Geological RegionNestled within the expansive White River National Forest, McDonald Flats occupies a unique geological niche near Green Mountain Reservoir. The 8,000-foot plateau showcases the region's characteristic high-altitude ecosystem, where hardy sagebrush has adapted to thrive in the thin mountain air and intense sunshine. This elevated terrain offers campers a front-row seat to the reservoir's impressive expanse and the rugged mountain topography that defines this corner of Colorado. The surrounding peaks tell ancient geological stories while providing a dramatic backdrop for your outdoor adventures.
