Copper Basin Road (Forest Road 51)
Pioneer Mountains mining history and hot springs
Copper Basin Road runs 24 miles from Mackay through the Pioneer Mountains to the old mining town of Copper Basin, climbing through sagebrush foothills into aspen groves and finally pine forests at 8,400 feet. The well-maintained gravel route passes the stone ruins of the Copper Basin mill and several prospect holes from the 1880s copper boom, with side spurs leading to natural hot springs at Sunbeam and the restored Pioneer Cabin.
This easy trail works for any high-clearance vehicle, even stock SUVs, making it perfect for families wanting backcountry access without technical driving. Open May through October with the best wildflowers in July, though afternoon thunderstorms are common in summer. No permits needed, and Mackay offers full services 30 minutes away. The payoff is excellent dispersed camping in alpine meadows, soaking in undeveloped hot springs, and exploring one of central Idaho’s most accessible mining districts with genuine Old West history.
