One of the most beautiful trails I have ever experienced. While this is listed as a moderately strenuous trail, my children aged 11 and 6 were able to hike the entire thing with no trouble. We like to make many stops, though, to take in everything around us and take pictures, so the entire hike took us about 4-5 hours. We could easily have taken more time - there is so much to see!
When we went, the waterfall was at low water and the creek was not running in most places, and the adventure was still fun and scenic. The small cave was a nice cool-off on an 85-degree day, and the large cave was breathtaking. The fall colors were beautiful.
The way out is steep, and the very last twenty or so steps of the "switchbacks" is a tough scramble on loose soil. You'll get your cardio! On the way down, the trail has lots of large, loose stones, so I would recommend hiking boots or shoes with good ankle support.
I can hardly wait to hike this again when the water is running high.
We loved this trail. Exploring the caves was fun and more than we expected them to be. We saw three types of salamander among other interesting creatures. The river isn't far away so enjoyed cooling off in the water once we were finished hiking. Great hike, will be coming back for more. Highly recommend.
