Hassler's Mill Creek drains a deep valley on the east side of Fort Mountain and forms a long, cascading waterfall along the way. The total vertical drop at Hassler's Mill Creek Falls is about 60 feet, but it occurs in a gradual series of stairstepping tiers. Bike Trail #301 affords a great overview of the waterfall. You can scramble out on the rocks below the middle tier for a closer look at the waterfall's most scenic segment.
