Ptarmigan Tunnel Trail Professional Review and Guide
"This 1930s man-made tunnel is quite a backcountry engineering feat, created so horses and hikers could move from one valley to the next without traversing a dangerous pass. The huckleberry-laden hike to the tunnel unveils wildflower-thick meadows, waterfalls, turquoise lakes, and jagged mountains; it’s well worth every foot of the 5.8-mile climb."
--Jean Arthur, Top Trails: Glacier National Park: Must-Do Hikes for Everyone (Wilderness Press).
