Johnstone Peak is an fairly popular and accessible peak close to Sun Valley with great views of the Valley area as well as the spectacular crest of the big Pioneer Peaks. There are many different ways to access the summit, all no more difficult than class 2.

Getting There

Johnstone Peak's summit is 7 miles east of Ketchum Idaho. Depending on the route you take to the summit, your access point will be different.

From the North - Pioneer Cabin Trail: Travel northeast from downtown Ketchum on trail creek road for 4 miles. Turn right on Corral Creek Road and drive 4 more miles until you reach a trailhead. [Note Trail creek Road is not cleared during winter]

From the West - Trail Creek Cabin: Travel northeast from downtown Ketchum on trail creek road just past the resort to the resturant parking lot.

From the South - South Ridge: Drive South from Ketchum on Idaho 75 for 5 miles and turn east (left) at the East Fork stoplight. Continue on this road for seven miles through the town of Triumph to Hyndman Creek Road 203 where you will turn left and drive an for approx 3.5 miles as if you were heading the hyndman creek trailhead. There is no trailhead or established trail for this route. [Note: Hyndman Creek road is usually kept clear in winter for the first 3 miles or so due to homes - conditions after that will vary based on recent weather]

Red Tape

No Summit fees. I am unaware of any trailhead fees. Seasonal access will depend on snow volumes.

When To Climb

The mountain can be climbed any time of year with good trailhead access and reasonable judgement on snow conditions. It offers a good snowshoe in winter.


Federal Gulch Campground is located back on East Fork Road past Hyndman Creek Road.
