The Siyeh Pass Trail is certainly one of the more challenging trails in Glacier National Park … actually in all of Montana. Popular trails like the Highline Trail and Grinnell Glacier Trail are worth a spot on every expert hiker’s bucket list. But one that I believe deserves just as much attention, and is just as challenging, is the Siyeh Pass Trail.
