What Travellers Say
Reviews Summary
Gunsight Lake is lauded for its breathtaking alpine beauty and the rewarding challenge of the Gunsight Lake Trail. Visitors appreciate the stunning mountain backdrops and the clear, blue water, though it's noted to be very cold. The trail's length and potential for wildlife encounters are significant considerations, and backcountry camping requires advance booking.
"Beautiful lake with backcountry camping spots that must be reserved. This lake is pretty cold, I could only stay in for a few minutes when it was 75* outside in August.
I posted a picture of a trail sign with the distances from the lake.
The lake has very little rocky beach area. It can only accommodate about 12 people.
There were some flys that bite and mosquitoes that were a bit annoying.
There are 2 enclosed toilets in the camp area and a pole to hang bear bags."

For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids
However, families looking for a taste of Glacier's beauty might consider shorter, more accessible hikes in the vicinity or exploring areas closer to Lake McDonald Lodge or St. Mary Lake. If a family is very experienced and prepared for a long day, and the children are older and accustomed to challenging hikes, it could be an option, but thorough preparation and realistic expectations are key. Always prioritize safety and consider alternative, less demanding trails within the park.
🎒 Backpackers & Serious Hikers

The trail's length and elevation gain demand a good level of fitness and proper gear, including sturdy hiking boots, navigation tools, and sufficient food and water. The stunning scenery and remote feel make the effort entirely worthwhile for those seeking a true backcountry adventure.

The Gunsight Lake Trail Experience
As you ascend, the scenery becomes increasingly dramatic. A significant highlight for many is the view of Jackson Glacier, a remnant of the park's namesake ice masses. The trail also leads you across Gunsight Pass, offering panoramic vistas that truly capture the grandeur of the Lewis Range. The journey is not for the faint of heart, with some sections being steep and rugged, but the payoff is immense.
It's crucial to be well-prepared for this hike. Bear safety is paramount, as this is active grizzly bear country. Carrying bear spray and knowing how to use it, along with making noise on the trail, are essential precautions. Additionally, be prepared for variable weather, even in summer, and pack plenty of water and snacks. The lake itself, while breathtaking, is known for its frigid temperatures, so swimming is typically a brief, bracing experience. [^review]

The campsite is equipped with basic amenities, including two enclosed toilets and a bear bag hanging pole, which is vital for food storage in grizzly territory. Reservations for these coveted spots are essential and typically fill up months in advance. Hikers planning to camp should be proficient in backcountry travel and understand Leave No Trace principles to help preserve this pristine environment. [^review]
Camping here allows for exploration of the surrounding area without the pressure of a day hike. You can enjoy the tranquility of the lake in the early morning or late evening. Remember to pack all necessary camping gear, including a bear-resistant food container or bear canister if required, and be prepared for cooler overnight temperatures.
