We love all the National Parks in Utah. Hidden Springs is a great hike at Zion. It is mostly switchbacks but once you reach the top it gets very interesting. While on the shuttle buses, keep alert as we saw our first pair of foxes in the wild playing in the grass along the road. I don't know the length of your rig but we entered the east entrance of Zion and were 5 inches over the fifty foot limit and had to drive 102 miles around and come in through Springdale. When we left we had to drive the long way to Bryce due to the length requirement. We drove through the area in question in our truck and can't understand why we had to waste all that fuel? The National Parks are always the high point of our Snow birding trips each year. I hope you don't miss Capitol Reef, Canyonlands, and Arches. The hike to Double O arch is not to be missed at Arches,
