Zion National Park has built a name for itself and for good reason. We went in the beginning of December, which if you don’t mind it being a little on the colder side, it was a good time due to less crowds and you can drive the entire park. During the peak season, the northern part, where Angel’s Landing is located, is blocked off and you have to get tickets for the shuttle, which sell out quick. If you plan on hiking The Narrows, I would recommend renting the dry pants/dry suit (during the winter time) along with booties (neoprene socks) and water shoes. They grip the rocks pretty well. You will greatly reduce your chances of falling in the water completely if you take it slow and use a hiking stick as well. You can rent them and additional equipment from the local outfitter, Zion Outfitter. They are located right outside of the National Park gate by the Visitor Center heading towards town.
Angel’s Landing is one of the top attractions in the park. This hike is physically challenging and you will have to hold on to chains at certain points of the hike, so make sure you have decent upper body strength. Oh, and if you’re afraid of heights…do not look down. It is about 4.4 miles around trip, and there is no water on the trail. I would take a camelback so that your hands are free while climbing.
