The Gunsight Pass Trail is 20.6 miles long starting on Going to the Sun Road between Logan Pass and St Mary Lake and ending at the Lake McDonald Lodge. With day hike access to 2 glaciers, stunning scenery and 3,000 feet of total climb, it is deserving of a multi day backpacking experience.

Amazing views. I hiked from the trail head all the way to Mcdonnalds lake. Very amazing hike! Watch for goats and bears! The ice fields were sketchy, so bring ice axes or trek polls.

Amazing trail. Great condition. Marked perfectly. Hemlock grove and shade for first 2/3. And then mountain views for final 1/3 into sperry chalet. Amazing experience having lunch and coffee at chalet. We climbed 3400 ft in 6.4 miles.

Great backpacking trip - amazing views from Gunsight Pass after a great night camped at the lake. Lots of mountain goats, and a bear was wandering around camp on the way down. A few snow fields to cross, but in mid September it had not yet started snowing yet and was doable just with hiking shoes.

Always check conditions before going to see if you need an ice axe like we did, but absolutely gorgeous!!!! Mountain goats, bears and marmots.

We trained last spring in Austin to prepare for this great hike. This trail is only open about 100 days per year!
The trail is in good shape except for the initial
Portion of the lower trail which needs serious trimming. Be sure to bring bear spray as this is bear haven! The trail views are absolutely spectacular and can only be seen from a plane or on this hike.
Bring lots of water in late summer or bring water filter as we used both. We hiked in late august and while cool in the morning it got very warm in the afternoon sun and we went through about 40-50 ozs of water. You will encounter very friendly Mt goats on trail and two followed us for over a mile!
Best to acclimate to altitude before trying some of Glaciers hikes-- allow 3-4 days.
This is a serious hike but not technically hard. Just a long slow climb on day 1 crossing two Mt passes and crossing a snow field.
Plan ahead (by6-9 months) and stay at Sperry Chalet on the Mt. Well worth the cost for a great meal, entertainment by the staff and a comfortable bed!
The hike out is all downhill and enjoyable.
We did it at age 60 to celebrate!! We plan on going back and doing it again!
We took 8 1/2 hrs on day one and 4 hrs on day two and maintained a nice but enjoyable pace.

Very nice hike with wonderful views along the way along with some side trails worth of exploring. We hiked the trail in early June and only passed by one other person on the trail that day. Although we had to navigate through snow for the final 1 1/2 miles, it was worth it. As my wife and I stood by Gunsight Lake we were treated to; not one but two, avalanches that created snow falls that drained into the lake for almost 20 minutes; and only we got to see it, spectacular. I highly recommend this hike anytime you are in East Glacier

Just as nice as it was in 1965 when we climbed Mt Jackson and exited via Sperry Chalet.
This is a great hike with simple logistics. Start at the Apgar Transit Center at 0700 (be there early to get the first bus). Take the shuttle to Jackson Glacier overlook and have a vehicle waiting at Lake McD Lodge where you can swim and have a refreshing drink of your choice within minutes of completing your hike.

Most beautiful place I've ever been. It's a 6.2 hike to gunsight lake but well worth the hike. Total serenity and plenty of trout in the lake. Leave early because it takes 2.5 hours to get there and spend the day
