Zion is located in the southwest of Utah. The main attraction of this national park is the Zion Canyon. The walls of this canyon are red and tan-coloured, because the sandstone was carved out by the Virgin River. The park has four life zones. Because of this you can find a huge variety in plants and wildlife. The only way to enter the park is by bus, bike or on foot. The bus drives on a nice new road, because every winter a huge part of it is flushed away by the river.
