From the parking lot at Camp Misery, it's 3 miles and 1,778 feet of elevation gain up the trail to the summit of Mt. Aeneas. At its summit, Aeneas measures 7,528 feet above sea level. The first 1/2 to 3/4 of the ascent is below tree line, but there are still a few opportunities for views. The last section, though, is above the tree line as you traverse a ridge on your way to the ultimate summit, and the views of the Flathead Valley on one side and the endless mountains on the other sides are totally worth all of the effort! An above-tree-line view is pretty rare in this area of Montana, too.
From Bigfork, drive north on 35. Take a right at 83 at the gas station (first stop light outside of town). Take a left onto Foothills road? at the Echo lake cafe/school/gas station corner. Take a right on 5292/Jewel Basin Road and drive all the way up to Camp Misery at the end.
