The mountain was named after Major William Hyndman, an early settler,[4] and businessperson in the local mining industry.[5] The first recorded ascent of Hyndman Peak was made in 1889 by W. T. Griswold and E. T. Perkins.[6] The primary route to the summit is class 2, which along with its proximity to Sun Valley makes it a popular destination.
The trailhead to hike to Hyndman Peak is located at the end of Sawtooth National Forest road 203 along Hyndman Creek. The primary route is approximately six miles (10 km) one way from the trailhead and traverses through Hyndman Basin, which is bordered by Hyndman, Old Hyndman, and Cobb Peaks.[7] The route follows an unmaintained trail and ascends the Hyndman-Old Hyndman saddle before reaching the summit.
