About Grotto Falls
Grotto Falls is a 40-foot fan in Montana, on Hyalite Creek.
Fed largely by snowmelt, it runs hardest in late spring and early summer and can thin to a trickle by late season.
Plungeworthy rates Grotto Falls 7.3/10 — worth the drive. The score weighs its scale, how confidently it's mapped, and its character.
What you'll find
Hyalite Creek arcing off an overhung ledge into a shadowed rock bowl — the first of eleven falls on the canyon's famous waterfall trail, and the easiest to love. The lower trail is built wide and gentle; stone steps finish the approach.
