— If you hike to Aster Park Overlook at Glacier NP, you will pass by this beautifully refreshing waterfall along the trail: Aster Falls. Located in the Two Medicine Lake area, the roundtrip hike here is only 2.8 miles (4.5 km) with very little elevation. It is an easy hike for sure, and one that you won’t want to miss. As Glacier Guides said, this is the type of hike for “maximum views with minimum effort.”
