About this place

Thompson Peak Trail earns you mega views by climbing 4,200' to the tallest peak in the Sawtooth range. Absorb some Idaho magic along this beautiful 13 mile out-and-back trek.

The Sawtooths are known for its craggy shapes protruding from central Idaho. Although the hike to Thompson Peak isn't necessarily a rare or tremendously physical feat, it's a proud, boastful moment bagging the tallest peak in the range. Here's the scoop:

To reach Redfish Trailhead, head south of Stanley for about 6 miles and follow signs for Redfish Lake. Just before the lodge there is a parking lot dedicated to hikers and backpackers. Nothing is more of a buzzkill than returning from a hike to a parking ticket, so make sure you've acquired a forest pass prior to the journey. Insider Tip: catch a world-class sunrise near the Redfish Lake Lodge before setting off on the hike. Bring your camera and thank me later!

The hike to Thompson begins from the parking lot. Follow the trail across the road and begin hiking along Fishhook Creek. Take a right (north) at the first junction .8 miles into the trek and head toward a grove of aspen trees. The trail will lead to a ridge above the aspens and run in the direction of a few photogenic mountain peaks. The next couple miles of hiking provides crazy views that'll make you wonder why you've never been there before. Pass through the wilderness boundary (be sure to sign a free permit) and hike until you see the next fork in the road. Continue left. Many times there will be a log in the direction of Thompson Peak. The other, more popular trail (to the right), leads to Marshall Lake.

Shortly after stepping over the log, the trail starts climbing until it unofficially stops in a hanging meadow. Continue through and above the meadow and you'll reach an intensely blue lake at the base of Thompson. This lake would make a good destination for hikers not wanting to scramble up to the summit as it provides vast views and the water is so blue it looks fake, like it came from a mini-golf course. Scramble up to the saddle and follow the faint trail over rocky terrain to reach the peak at 10,751'.

After conquering Thompson, hit one of Stanley's many local hot springs and be sure to stop by The Stanley Club for a post-hike pint. You earned it.

Beautiful hike, the last mile-ish is pretty tough with a lot of elevation gain in a short distance and some boulder hopping and sidehilling. ...
