This is one of the shortest hikes you'll ever take, but the payoff is really pretty: You get good views of Lake Creek and the foaming waterfall it creates as it spills downstream. The lake then runs under the Beartooth Scenic Byway, eventually joining the Clarks Fork Yellowstone River.

The Gallagator Trail is a heavily used crushed gravel commuter trail in Bozeman. It attaches to many other commuter trails and walking/biking trails, and it has multiple official trailheads. There are a lot of trees and vines along the trail so it stays primarily shaded, and there is a creek that runs next to it nearly the entire length of the trail.
