About Lost River Range

The Lost River Range is a rugged and remote mountain range located in central Idaho. Stretching over 40 miles, the range is characterized by sharp, jagged peaks, deep glacial valleys, and dramatic limestone cliffs. The terrain is challenging, with steep, rocky slopes and numerous scree fields. Due to its isolation, the Lost River Range sees relatively low visitation compared to other mountain ranges in the state, offering a true wilderness experience for outdoor enthusiasts.
