Beautiful medium effot hike about 2-3 hours depending if you linger at the top. Make sure you go to the top where the pools are, they're beautiful and you may see climbers on the walls of the canyon at the backside. Recommend packing a lunch. The falls are gorgeous. There is a very steep section of stone steps about 2/3 of the way up, but it's not very long. Way better than Johnston Canyon in my opinion, but I don't like hiking single file behind / around hundreds of people.
And what a view nearly all the way along!
