Zion National Park is one of the great, epic Parks of America. Often understated, Zion is an encapsulated hidden island among the ocean of Utah desert. On a top list of park areas is the Narrows region toward the back of the river that flows along the entire park. This amazing huge slot canyon feature is a wonderland of beauty and adventure. Go. Waterfalls, steep cliff faces, hanging plants and leafy trees defy the surrounding imposing harsh desert.
