Big Bayhorse Campground sits at 8,615 feet beside Bayhorse Lake in the Salmon-Challis National Forest. The eight sites accommodate tents, RVs, and trailers under 32 feet. A narrow, steep access road rules out larger rigs. Each site has a picnic table, fire ring, and grill. Vault toilets are available, but there's no water.
Big Bayhorse Campground offers dispersed camping suitable for tent campers and RVs, as well as day-use picnicking.
Historical Significance
The ruins of Bayhorse, a 19th-century mining town, sit nearby. Weathered structures and abandoned mine shafts mark where prospectors chased silver veins through these mountains. The boom-and-bust cycle left behind a ghost town visitors can explore on foot.Weather and SeasonsThe campground opens July 1, after most snow melts at this altitude. Summer days reach 55–75°F, while nights drop to 30–40°F. Wildflowers line the trails in July and August. Flies swarm during the day, and mosquitoes rise from the lake at dusk. Bug spray is essential. Early-season campers sometimes wake to frost.
ElevationPerched high in Idaho's mountain country, this alpine retreat sits at an elevation where the air grows thin and the views stretch endlessly. The campground's lofty position means shorter seasons but rewards hardy souls with cooler summer temperatures and dramatic vistas that change with each passing cloud.
Natural Features and SceneryBayhorse Lake reflects the surrounding peaks in its surface, especially at dawn and dusk. Pine and fir forests frame the shoreline, with rocky outcroppings revealing the area's volcanic and sedimentary geology. The lake and nearby mountain streams hold trout. At this elevation, the air is thin and clear. Stars are vivid after dark.
Geological RegionDeep within the Salmon-Challis National Forest, this high-altitude sanctuary showcases the raw geological drama of central Idaho. The surrounding peaks tell a story written in stone—ancient sea beds thrust skyward, volcanic intrusions, and mineral veins that once drew miners to these remote valleys. Today, this rugged terrain offers modern explorers a chance to walk through millions of years of Earth's history while camping where prospectors once pitched their tents in search of silver fortunes.
Scenic ViewsVisitors frequently note breathtaking views of the night sky due to minimal light pollution. Some reviews state that the campground is a couple hundred yards away from the lake.
