Gunsight Pass Trail

This trail is considered difficult and is best suited for experienced hikers. While no single section requires expert skills, its overall length of approximately 19-22 miles and significant elevation changes (around 3,000 to 5,260 feet total gain) make it a strenuous undertaking. Most hikers complete it as a two or three-day backpacking trip rather than a day hike.

The Gunsight Pass Trail is a point-to-point route, not a loop. This means you'll need to arrange transportation between your starting point (often near St. Mary, like Jackson Glacier Overlook) and your end point (typically Lake McDonald Lodge). Many hikers use a car shuttle system or utilize the park's shuttle services.

The starting point for the Gunsight Pass Trail is commonly near St. Mary, often at the Jackson Glacier Overlook. Parking availability can vary, especially during peak season. It's advisable to arrive early or use the Glacier National Park shuttle system to access the trailhead, particularly given the point-to-point nature of the hike.

To hike the Gunsight Pass Trail, you'll need to pay the entrance fee for Glacier National Park. If you plan an overnight backpacking trip, a backcountry permit is mandatory. These permits are highly sought after and can be difficult to secure, so plan well in advance. Always check the official Glacier National Park website for the most current regulations and permit application processes.

You'll experience a diverse range of terrain. Early sections might take you through dense forest and lush alpine meadows, sometimes with waist-to-thigh-high vegetation. As you ascend, you'll navigate rock outcroppings, switchbacks, and potentially snowfields that can linger well into the season, especially around Gunsight Pass. The trail also crosses the Continental Divide, offering varied landscapes throughout.

The route is packed with stunning views. You'll see massive mountains, Mirror Pond with Citadel Mountain, and several turquoise glacial lakes. Key highlights include Gunsight Lake, known for its brilliant color, and the striking Lake Ellen Wilson, visible from Gunsight Pass. You'll also pass waterfalls, have views of Sperry Glacier, and eventually descend towards Lake McDonald. Don't miss the historic stone warming hut at Gunsight Pass.

The trail is renowned for its abundant wildlife. Keep an eye out for mountain goats, hoary marmots, moose, and bald eagles. Grizzly bears are also present in the area, so it's crucial to be bear-aware, carry bear spray, and know how to use it, especially in areas with dense vegetation.

The best time to hike is typically from late July through September. Earlier in the season, snowfields can make sections of the trail impassable or require specialized gear like an ice axe. Always check current trail conditions with park rangers before you go, as weather in the mountains can change rapidly.

Given its difficulty and remote nature, safety is paramount. Be prepared for rapidly changing weather, carry plenty of water, and bring layers of clothing. In early season, an ice axe might be necessary for steep snowfields. Bear spray is essential due to active grizzly bear populations. The historic warming hut at Gunsight Pass can provide crucial shelter during storms.
