People don't become captivated by southern Utah, they become obsessed by it. It's got an attraction that's difficult to pin down, let alone describe.
People tend to think of southern Utah as a land of canyons, and it certainly is.
But most of the country is taken up by the high plateaus and mesas into which the canyons are carved. Much of this variety is set aside in Utah's five National Parks Arches , Bryce Canyon , Canyonlands , Capitol Reef and Zion . The best time to visit them might be the dead of winter. Visitation to Utah's five National Parks drops dramatically in the winter. Only Bryce Canyon actually caters to winter visitors because its higher elevation draws cross-country skiers and snowmobilers, but there's plenty to do at all of the parks.
