Illinois Peak Professional Guide
Detailed Trail Description from our Guidebook
"A day hike or overnighter through spectacular—and seldom seen—mountain scenery along the Bitterroot Divide. Perhaps because the higher portions of the Bitterroot Mountains north of Lolo Pass aren’t visible from a major highway, they remain relatively unknown. On a map they are easily overlooked and underrated. None of the peaks exceeds 8,000 feet, but because they are among the westernmost of Montana’s mountain ranges, the Bitterroots receive an abundance of rain and snow.
The result is an abundance of alpine scenery at lower elevations than in most mountain ranges. Many ridgeline trails are dry and parched, but this hike goes through a lush, green landscape. At 7,690 feet, Illinois Peak is one of the highest peaks in the northern Bitterroots."
