If a person enters from the Eastern side of Zion National Park (in Utah), there is a spectactular drive into the park area, with mesas and switchbacks.
The view in the photo is from Zion Lodge, where we stayed. There is a shuttle bus with local information conveyed by the drivers or by a recording.
We saw wild turkeys roosting in trees and a great blue heron fishing in the Virgin River (which created the canyon) during our shuttle bus drive.
There are hikes in varying degrees of difficulty from the canyon upwards.
