About Eastern Centennial Mountains

The Eastern Centennial Mountains are a rugged and remote mountain range located in eastern Idaho. Stretching across the border with Montana, this range is characterized by steep, rocky peaks and deep, glacially-carved valleys. The terrain is largely untamed, with few maintained trails, making it a true wilderness experience for the adventurous outdoor enthusiast. The mountains are home to abundant wildlife, including elk, bighorn sheep, and black bears, adding to the sense of isolation and raw natural beauty.
