A great day hike and vertical workout - Sacajawea Peak is the perfect Gallatin Valley trail. Bring your windbreaker and be ready to brace yourself towards the top - it gets quite blustery without the cover of trees and landmasses. Sacajawea Peak is located in the Bridger Mountain range right outside of beautiful Bozeman, Montana. The trail hike is a little over 2 miles long and best done in the summer months. Be prepared for a climb!
