Whether you're seeking a challenging day hike or the start of a multi-day backpacking epic, the Gunsight Lake Trail promises an adventure you won't soon forget.
Often hailed as a true gem for those looking for longer trails with deep access to high-alpine beauty, the Gunsight Lake Trail showcases an impressive array of natural wonders. From the moment you set foot on the path, you're immersed in a landscape sculpted by ancient glaciers, where every turn reveals a new vista more magnificent than the last. Prepare for a full day of exploration, as this out-and-back route to the lake demands endurance but rewards with visual splendor at every mile marker.
Embarking on Your Journey: From Jackson Glacier Overlook to Mirror Pond
Your grand adventure on the Gunsight Lake Trail officially begins at the easily accessible Jackson Glacier Overlook, strategically located along the famed Going-to-the-Sun Road. This starting point itself offers a prelude to the grandeur ahead, providing immediate views of the St. Mary Valley and the impressive Jackson Glacier. Parking is available, and for those looking to ease their journey, shuttle services from Lake McDonald provide a convenient option to reach the trailhead.
From the southeast end of the parking lot, follow the well-marked trailhead signs that lead you towards Deadwood Falls and the gentle murmur of the St. Mary River. The initial miles of the trail weave through thick, verdant forests, offering a serene start to your hike. While these sections might limit sweeping panoramic views, the dense canopy provides a refreshing respite and a chance to truly connect with the forest environment. Keep an eye out for openings in the trees, particularly near the St. Mary River, which reveal glimpses of the majestic high peaks that tower above the valley, hinting at the vistas to come.
Approximately 4.3 kilometers (2.7 miles) into your hike, you'll reach the tranquil Mirror Pond. This picturesque spot lives up to its name, often reflecting the surrounding peaks and sky with stunning clarity, making it a perfect early rest stop and photo opportunity. It’s a moment of calm before the trail begins its more demanding ascent, inviting you to pause and appreciate the peaceful beauty of this natural mirror.
Ascending Towards Alpine Splendor: Views, Glaciers & Gunsight Pass
Beyond Mirror Pond, the character of the Gunsight Lake Trail begins to transform. As you push past the 6.9-kilometer (4.3-mile) mark, the terrain gradually becomes rougher, signaling the start of a more sustained and challenging climb. This is where your endurance will be tested, but the rewards are truly immense. The path carves its way through the brushy slopes of Fusillade Mountain, and as the vegetation opens up, hikers are treated to increasingly expansive and dramatic views.
Here, the landscape unfolds in a breathtaking panorama, revealing several iconic features of Glacier National Park. You'll witness the rugged beauty of Citadel Mountain, the elegant peak of Mount Logan, and get closer views of the ancient ice of Blackfoot Glacier and Jackson Glacier. Looming large, Mount Jackson dominates the skyline, a constant companion as you ascend. These glaciers, remnants of a bygone era, serve as powerful reminders of the park's geological history and provide a stark, stunning contrast to the vibrant greens of the alpine meadows.
As you continue your climb, reaching approximately 8.9 kilometers (5.5 miles), the ground levels out slightly, offering a much-deserved break and an even more spectacular sight: Gunsight Pass itself. Nestled dramatically between the imposing forms of Gunsight Mountain and Mount Jackson, the pass presents a striking natural amphitheater. Just a little further, at around 9.8 kilometers (6.1 miles), the sparkling waters of Gunsight Pass Lake emerge, a pristine alpine pool that mirrors the surrounding peaks and signals your near approach to the main destination.

Gunsight Lake: A High-Alpine Oasis Amidst Soaring Peaks
The culmination of your challenging ascent is the majestic Gunsight Lake. This stunning high-alpine lake is a true oasis, set amidst a dramatic backdrop of soaring peaks at the very head of the St. Mary River Valley. The views here are nothing short of spectacular, creating an immersive experience that feels worlds away from everyday life.
Looming directly above the head of the lake are the formidable Mount Jackson and Gunsight Mountain, their rugged faces often streaked with snow even in summer, creating a powerful sense of scale and grandeur. To the north, Fusillade Mountain adds to the impressive skyline, completing a natural amphitheater of rock and ice. One of the most enchanting features of Gunsight Lake are the waterfalls that spill gracefully down the slopes of Gunsight Mountain, cascading directly into the clear, cold waters of the lake below.
Upon reaching the lake, you'll discover inviting sandy beaches along the lakeshore. These pristine stretches of sand provide the perfect spot to relax, soak in the panoramic views, and enjoy a well-deserved picnic lunch. The tranquility of the surroundings, combined with the sheer beauty of the peaks and glaciers, makes Gunsight Lake an ideal place to rejuvenate before beginning your return journey.

Remember that the hike to Gunsight Lake and back is an out-and-back trail, meaning you will retrace your steps. For those with backcountry permits and a thirst for an even longer challenge, the full Gunsight Pass and Lake Trail extends nearly 21 miles (one way) and offers options for extended backpacking adventures, connecting to destinations like Sperry Chalet, Lake McDonald, and Lake Ellen Wilson, featuring an overall 3,000-foot climb in elevation.
Wildlife Encounters & Essential Safety Tips
The Gunsight Lake Trail winds through genuine wilderness, meaning wildlife encounters are not just possible but probable. Glacier National Park is home to a diverse array of animals, including moose, mountain goats, bighorn sheep, and an abundance of birdlife. However, the most significant wildlife consideration on this trail is the presence of grizzly bears.
Sections of the trail, particularly through the brushy slopes, feature waist-to-shoulder-high vegetation, which can obscure visibility and make inadvertent encounters with wildlife more likely. To minimize risk, always make noise while hiking, especially when navigating dense brush or blind corners. Talk loudly, sing, or carry a bear bell to alert animals to your presence. Hiking in groups is also highly recommended, as it makes your presence more obvious. Always carry bear spray and know how to use it. Store food properly in bear-resistant containers if backpacking, and never leave food or scented items unattended.
Beyond wildlife, alpine weather conditions can change rapidly and unpredictably. Be prepared for all four seasons in a single day, even in summer. Pack layers, including waterproof and windproof outer shells. Bring plenty of water, high-energy snacks, a map, compass or GPS, and a first-aid kit. Inform someone of your hiking plans and expected return time. This trail is a significant undertaking; ensure you are physically prepared for the long distance and elevation gain before you set out.
Planning Your Epic Glacier National Park Hike
A successful trip on the Gunsight Lake Trail requires careful planning. Given its length and elevation gain (the full pass trail involves an overall 3,000-foot climb), it's considered a strenuous day hike to the lake and a challenging backpacking route beyond. The best time to visit is typically from mid-July through early October, once the Going-to-the-Sun Road is fully open and the snow has melted from the higher elevations.
For those planning an overnight adventure, remember that backcountry camping permits are required and must be obtained in advance through the park's lottery system or walk-up availability. Popular campsites along the Gunsight Pass Trail include Gunsight Lake Campground and Sperry Campground. Due to the trail's popularity, especially in peak season, arriving early at the Jackson Glacier Overlook to secure parking is advisable, or utilize the park's efficient shuttle service to avoid parking woes.
Remember to leave no trace: pack out everything you pack in, stay on marked trails, and respect the fragile alpine environment. Adhering to these principles ensures that the pristine beauty of the Gunsight Lake Trail remains for future generations of adventurers.
An Unforgettable Wilderness Experience Awaits
The Gunsight Lake Trail truly embodies the wild heart of Glacier National Park. It's a journey that challenges your body, nourishes your soul, and leaves you with indelible memories of some of the most spectacular mountain and glacier scenery on Earth. From the tranquil waters of Mirror Pond to the dramatic vistas of Gunsight Pass and the serene beauty of Gunsight Lake itself, every step is a testament to nature's grandeur.
