Easy well-maintained hike to the falls from the parking lot. If you want a little more interesting of a hike, make sure you don't miss the "connector", which adds some more climbing and descending, but it takes you closer to the Gallatin River, and there is another beautiful small stream that you cross along the way. Built up. nicely with boardwalks that would be fun on a mountain bike.
