10 mile round trip (not 8, like it tracked here). Awesome hike. Great views, amazing waterfalls. Get off of the beaten path to get to the good stuff. There are a few side-trips off of the trail here that are well worth the time/effort. Warning - if you don't like stairs... this is not for you. There are a TON of man-made staircases built in to the trail. They've done an amazing job maintaining this trail. Lots of hikers share this trail... way too many for our liking. We did 300 floors (tracked by Fitbit), so this is a leg burner. The run down is fantastc.
