Hyndman Peak is a huge, pyramid shaped mountain. It sits at the head of Hyndman basin, which is surrounded by big, rugged, 11,000+ peaks. The easiest route to the summit is class 2, a moderate scrambe after a 6 mile approach hike. I would say that about 10 people summit the peak on the average summer weekend. Technical climbs of the peak are also available, and I've talked with quite a few people that have climbed the peak and boarded down in the winter.
Hyndman Peak is the 9th highest peak in Idaho and a member of the Idaho 12ers, of which it is the easiest to climb (the rest are class 3). Still, it requires a 5,000-foot and 12-mile effort to ascend.
Drive five miles south from Ketchum on Idaho state highway 75 and turn (east) onto East Fork Road. Drive six miles east (1.5 miles past Triumph), then make a hard left turn up a hill at the sign which says "North Fork of Hyndman Creek". Drive another three miles to the first stream crossing where Johnstone Creek and other creeks come together. Cross Hyndman Creek, then continue on the dirt road to the north side of the creek for 1.25 miles until you come to a road closure sign and gate. Park here.
From the trailhead, follow the trail along side Hyndman Creek to the base of Cobb Mountain. Here the trail turns north and leads up a sagebrush covered hill to a small pond next to point 8724. Follow the ridge on the left-hand side of the creek northeasterly up to Hyndman basin. From Hyndman basin, the trail is faint, but just head towards the saddle between Hyndman and Old Hyndman. Once at the saddle, follow the ridge to the top of Hyndman Peak.
The Sawtooth National Recreation Area pass is history! There are no longer any fees to visit this area!!!
When To Climb
July - October are the best times to climb Hyndman. Climbing during the winter would add a around 7 miles roundtrip to the approach. There is also some avalanche danger in the winter, but the route can be done safely at times.
We camped right at the trailhead. Hyndman Basin, about 5 miles from the trailhead would be a great place to backpack into. There are trees and water in the basin.
The Idaho Outdoors Forum is a good source of conditions information.
This snotel site is on the lower route along Hyndman Creek and should give you an idea of snow levels.
Here is the phone number for the Ketchum ranger district office: 208-727-5000
We saw deer, elk, and got up close with mountain goats on our trip.
