This adventure can be a great day hike or overnight. Enjoy solitude with few crowds on this trail.
There are so many wilderness areas to choose from in Montana, it can be quite overwhelming. But try this on for size: the Pintlers are essentially Glacier National Park, without the people. Not only does it traverse the CDT, but chances are you won't see a lot of people, if any, on your adventure.
The trail starts at the Lower Seymour Lake Trailhead and is relatively flat for the first couple of miles. You don't gain a lot of elevation along the way. It's about 5-7 miles to the lake, which sits in a cirque. You can keep hiking about 2 miles to Goat Flat and beyond.
