Glacier National Park offers a plethora of incredible hikes, but Ptarmigan Tunnel stands out with its unique charm. Though it wasn’t my absolute favorite, I was captivated by the tunnel itself and the breathtaking views it offered. If I had more time, I would have definitely paired this hike with a longer, multi-day trek deeper into the backcountry.
About the Ptarmigan Tunnel Hike
Distance: 10.6 miles | Type: Out & Back | Elevation Gain: 2,375 feet | Avg. Time: 5-6 hours | Difficulty: Hard
Starting from the Many Glacier parking lot, the Ptarmigan Tunnel trail leads hikers on a 5-mile journey to the tunnel. Built in the 1930s by the Civilian Conservation Corps (CCC), this 230-foot tunnel through the Ptarmigan Wall at 7,200 feet is the trail’s centerpiece. It’s well known for its switchbacks and breathtaking views at the tunnel’s end. It’s also a common area for grizzly bear sightings, so hikers are advised to carry bear spray and hike in groups.
While the trail continues past Ptarmigan Tunnel for multi-day hikers, the day hike turnaround point is typically at the tunnel. Many hikers also combine this trail with the Iceberg Lake Trail, which shares the first 2.8 miles of the route.
Best Times to Hike Ptarmigan Tunnel
The Ptarmigan Tunnel is accessible most of the year, but winter closures affect the Many Glacier road. Summer is ideal with the least snow, while late spring and fall offer fewer crowds.
Remember, Many Glacier is within Glacier National Park’s fee area, so ensure you have a valid pass.
Getting There
The trailhead is easily located near the Many Glacier Hotel and campground.
By Car:
Parking is available near the trailhead, though it can get busy. If approaching from the west side of Glacier, you may need to detour around the park unless you have a specific car reservation.
By Shuttle:
The Hiker’s Shuttle, operated by Xanterra, services the Many Glacier area, departing from St. Mary’s Visitor Center. Note the shuttle isn’t free, and transfers may be required depending on your destination. More info can be found on the Xanterra Glacier Shuttle Page.
Hiking the Ptarmigan Tunnel Trail
The hike begins near the Many Glacier campground and Swiftcurrent Motor Inn. The trail, shared initially with the Iceberg Lake trail, starts through a mix of forest and open terrain with a steady climb.
At the 2.5-mile mark, you’ll cross Ptarmigan Creek via stepping stones—wear waterproof boots to stay dry. Shortly after, a trail fork directs you either to Iceberg Lake or Ptarmigan Tunnel, with the latter being the more challenging path.
The trail winds through forested areas, prime for wildlife sightings, including bears. At around 4.25 miles, you’ll reach Ptarmigan Lake—a perfect spot for a rest before tackling the steep switchbacks leading to the tunnel.
The ascent to the tunnel is grueling but rewarding, with opportunities to see bighorn sheep. Upon reaching the tunnel at 7,200 feet, you’ll experience a dramatic change in scenery, almost desert-like. The tunnel offers impressive views, making it a popular turnaround point for day hikers.
Should you wish to extend your adventure, the Iceberg Lake trail adds another 4 miles to your journey and is well worth considering if time permits.
