Shoes with good tread are recommended, as there is a lot of rock climbing on the second half of the hike. People who took smaller dogs had some difficulty with the rocks too. It was crowded, but everyone was pleasant and respectful, helping each other out when needed. I liked this hike because it was different; it required some focus to navigate.
Hiked this trail last Sunday with my dog. we made it to the waterfall no problem. there were some tough areas to get my dog through, but it was not impossible. was able to see water flowing through the small cave and the waterfall. took my running shoes which had no grip, so I highly recommend taking hiking shoes for those slippery areas.
