True to its wilderness character, this is a 'pack it in, pack it out' destination without water hookups or garbage service, encouraging a deeper connection with the natural world. Despite its rustic nature, the campground welcomes RVs and trailers up to 32 feet, and vault toilets provide necessary amenities for your mountain adventure.

Weather and SeasonsFrom June through October, this high-altitude haven transforms into a perfect mountain escape where warm summer days give way to crisp, star-filled nights. The campground's seasonal rhythm follows the mountain's lead—opening its gates as wildflowers bloom in early summer and closing as autumn's first snows dust the peaks.

Spring arrives late at this elevation, and winter comes early, making the prime camping months a precious window for outdoor enthusiasts seeking that perfect balance of warm days and cool nights.
ElevationPerched at an impressive 7,180 feet above sea level, this mountain sanctuary delivers the crisp, clean air and refreshing temperatures that only high-altitude camping can provide. Here, the thin mountain air carries the scent of pine and the promise of adventure.
Natural Features and SceneryImagine waking to sunlight filtering through a cathedral of lodgepole pines, their tall, straight trunks creating natural corridors through the forest. Beneath this evergreen canopy, soft grass carpets the forest floor, inviting barefoot morning walks to the water's edge. The centerpiece of this mountain tableau is the pristine 25-acre Mosquito Flat Reservoir, its mirror-like surface reflecting the surrounding peaks and sky. Visitors consistently praise this hidden gem—one camper called it a 'gorgeous little campground on a beautiful lake,' while families return year after year for what another described as a 'beautiful and peaceful' retreat perfect for 'fishing, family fun, swimming, and camping.' Whether you're casting a line at dawn, watching afternoon clouds drift across the water, or counting stars from your campsite, the scenery here creates memories that last long after you've packed up your tent.
Geological RegionNestled within the vast expanse of the Salmon-Challis National Forest, this campground occupies a special pocket of Idaho's mountainous heartland. The landscape tells a story millions of years in the making, where ancient geological forces created the perfect basin for Mosquito Flat Reservoir. Today, mature lodgepole pine forests dominate the terrain, their presence indicating the area's recovery from historic wildfires that once swept through these mountains. At 7,180 feet elevation, you're camping in a true subalpine environment where the forest meets the sky, offering expansive views of the surrounding peaks that define this corner of central Idaho's rugged wilderness.
