I've hiked here twice and have yet to see an owl, although in some areas there's an incredible amount of their poop on the walls. It's a very pleasant hike although there are some steep parts and rarely climbing up or down is necessary. The rocks are very sharp in this area so gloves are nice. From the parking spot, it's a short hike to Lake Mead. On my two trips to this spot there were pelicans, hawks, and blue herons around.
