During a 2004 vacation to Utah, I hiked a couple trails in the Paria Canyon-Vermilion Cliffs Wilderness Area, including the White House Trail that follows a wash into the canyon. It was mostly a get-acquainted hike as my driving schedule gave me time for only about an hour in and then an hour back out. I'd certainly like to see more of it.
