To get to Piegan Pass you have to start at the Siyeh Bend Trailhead, which is located 2.2 miles east of Logan Pass on the Going-to-the-sun Road. Or you could also start at the Piegan Pass Trailhead, but that would add much more distance to your hike and several hundred of climbing. The Siyeh Bend Trail offers a much more gradual climb to their destination.
For the first two hundred yards of the trail, you will be traveling next to the Siyeh Creek, then the trail makes a sharp turn into the forest. 1.1 Miles from the trailhead leads to the Piegan Pass Trail Junction. If you turn to the right you will end up at the Jackson Glacier Overlook, but if you turn left that takes you to the rest of the Piegan Pass Trail.
The part of the trail that is at a lower elevation passes through a dense spruce-fir forest, which thins out as you approach the Siyeh Trail junction, 2.7 miles from the trailhead. If you would like to continue on the trail, go left at the junction. If you would like to Siyeh Pass go right and that path will lead you to Preston Park and eventually to Siyeh Pass.
3 miles into the trail, the path finally rises above the tree line and onto the talus-scree slopes of 10,014 Mount Siyeh. If you look towards the south you will be able to see Jackson Glacier, and Blackfoot Glacier, the largest Glacier in the park. If you look to the west you will be able to see Piegan Glacier, which is just directly below the summit of 9200-foot Piegan mountain
4.5 miles into the trail, you will reach the top of Piegan Pass, which is the saddle between Piegan Mountain and Cataract Mountain. If you continue for another tenth-of-a-mile, you will get the most spectacular views of Angel Wing, Bishops Cap and Mount Gould along the Garden wall, as well as views into the Many Glacier Valley. This is whole area offers so many incredible views, which makes this one of the most beautiful hikes in Glacier National Park.
Ptarmigan and Mountain goats are known to be frequent inthe area, so be sure to keep a close watch.
Piegan Pass was on of the four sites to have a locomotive bell at its summit. An advertising agent with the Great Northern Railway and H.A. Noble, manager of the Glacier National Park Hotel Company, requested permission from the park to install the bells on the summits of several passes in the park. In September of the following year, the request was granted to place the bells at the summits of Swiftcurrent, Piegan, and Siyeh passes. Three years later another bell was installed at the Scenic Point in Two Medicine. The bells remained in their place for almost twenty years, but were removed by the hotel company to donate to the World War II metal drive.
This trail is also apart of the Continental Divide Trail, which runs from the Mexican border tin New Mexico, all the way to the town in Waterton Park in Canada.
