Did this hike back in March, when the waterfall was still frozen which was awesome! Was between 12-13 miles round-trip be we took the Service Road/Bugling Elk trails to the Falls and then the Marmot Passage/Scout Like trail back to the trailhead. Absolutely beautiful views on the way back! Highly recommend this hike, and don't let the distance stop you from doing this hike it really is moderate. Also, take the map it was very useful!
