Lava Lake is a popular hike off of US 191 in the Gallatin Canyon. Only a short drive from Bozeman, MT the lake is a popular place to fish, swim, or just relax.
The 6 mile round trip to Lava Lake is a steady climb that runs beside Cascade Creek through the Lee Metcalf Wilderness. The trail starts at the Gallatin River and continues upward through dense evergreen forest. There are no confusing intersections but is quite rocky and considered to be moderate in difficulty.
Due to the dense forest, views are limited until you get to Lava Lake. In the first mile you will walk by a summer cabin, as you get closer to the lake the trail begins to have switchbacks and then opens up to some small meadows. Snow may still be present on into May, and the water is cold and refreshing throughout the summer.
