The waterfall is unnamed, which is surprising considering its height and beauty. The trail up to the falls is an easy hike, but once at the falls, if you want to get down to the base of the falls, there is a bit of a scramble down (and up).

Beautiful trail, unique waterfalls, but the road to get to the start of the trail is terrible. Want to hike this again so badly but don't want to put our car on that road.

Beautiful hike! Took my 2 dogs with me and they enjoyed it as well. There was a huge tree down that made it difficult to get to the 3rd waterfall but other than that it was great!

Enjoyable hike with impressive waterfalls. Trail starts out wide, but narrows significantly which makes passing others on the trail difficult. I'd definitely come back and camp next summer

We took our 6 and 8 year olds. Fun for everyone. Loved hiking around the "creekbanks"...

The trail was great, however, the three mile drive to the trailhead is awful. Horrible potholes on a narrow road so it's difficult to avoid them.

We only went to the first waterfall because we had so many littles but the trail was great and we went down to the waterfall and it was beautiful! My 3 year old made it all the way there and back.

Nice easy hike. The waterfalls aren't too far into the hike and worth visiting. Continue on across a bridge and you will see a down tree over the water, this is s very nice place to sit and enjoy the sights and sounds.

Went on a Sunday and it was not too busy at all, maybe 10 groups that we saw total. Ran from the trail head to the end clearing where the trail becomes undetermined. Very rocky with tons of branches, just gotta be aware while you run it. Still a little muddy in places so be careful running over them. Nice scenery to stop and look at including 2 water falls and about 5 clearings too watch the river flow.
Be prepared for the road coming in, lots of potholes.

A fun hike with amazing views along the trail! The trail consists of four large waterfalls, last one being 2/3-of-the-way out on the trail. It ends at a river that is surrounded by quaint camping sites. Can't wait to go back!

Did the full 10 mile version up to a great spot in the river, past the 2 waterfall viewing spots. Bottom is crowed with lots of kids, but it thins as you keep going. Beautiful trees as far as your eyes can see.
