Thompson Peak

Thompson Peak is a mountain summit in the Sawtooth Range that rises to 10,751 feet and stands as the highest point in this chain within Idaho. The peak offers multiple climbing routes including the South Couloir and West Crack for different skill levels.

The peak received its official name in 1916 from the United States Board of Geographic Names, honoring an early explorer who was among the first to reach the summit. Since then it has remained a defining landmark of the mountain range.

The peak draws climbers who test themselves on its slopes and embrace the mountain experience. Local communities and visitors alike view it as a natural landmark that defines the character of this high country.

The hike begins at the Redfish Lake trailhead on well-marked paths that lead to multiple ascent options. Proper hiking boots and mountain experience are essential, especially where the route includes steeper climbing sections.

From the summit you can see Thompson Lake spread below along with numerous alpine lakes dotting the surrounding wilderness. These water bodies create a stunning network of peaks and basins that define this section of the range.
