I would rate this trail as difficult. Vail is already at 8150ft with this trail giving you a steady incline of +1000ft which was pretty rough on us coming from California coast only the night before. We went as far as the falls for this hike and took a lot of rest. I would say the very beginning is the steepest stretch, so don’t get discouraged when you start. There were a handful of flat areas a few meters long, with the valley opening being the longest. This area was a very beautiful view of the vegetation. For the falls you do need to cross two creeks but there are rock stepping stones, so your feet will not be submerged. A good portion of the path is rocky, so I’m glad we wore our hiking boots for this one.
