The east ridge provides the standard route to the summit, not exceeding Class II. It’s still a big day (or two) with lots of elevation gain. The journey begins from Hyndman Creek Trailhead, following an old jeep road for the first couple of miles, across sunny slopes in a creek valley. This portion is relatively flat, so you could ride it on a mountain bike to save time.
Around 7900 feet elevation, a worn footpath turns more steeply upward, leading through beautiful meadows and glades to eventually reach the basin below the peak. There you’ll strain to look upward at the Pioneer Mountains’ big three––Cobb Peak, Old Hyndman, and Hyndman Peak. The trail continues up to reach the shore of a small lake, which is a good place to camp for those wishing to make this a two-day ascent.
Above the lake, the trail pretty much disappears, but cairns may mark the route. Pick your way through talus and around cliff bands to gain the saddle between Hyndman and Old Hyndman Peaks. Once there, you’ll enjoy a view over the massive exposure of Hyndman’s east face. Then the only way to go is up, along the steepening ridgeline toward the summit. It’s aggressive hiking on blocky talus, perhaps using hands for stability here and there. You might wander left or right to find more stable rock along the way, but the route is generally straightforward to the top.
On Hyndman Peak, you’ll be standing on the roof of the Pioneer Mountains, overlooking all the peaks of this daunting range. Further ranges stretch in all directions, and on a clear day, you can easily see Idaho’s tallest––Borah Peak in the Lost River Range.
The ascent involves simple glacier hiking and/or short, straightforward rock scrambles. Equivalent to Alpine F, F+
