When you are standing on the edge of Horseshoe Bend, you may notice some blue and green rafts floating down the river. These visitors are enjoying the only half-day rafting trip on the Colorado River from the base of Glen Canyon Dam. Colorado River Discovery offers the most fantastic one day rafting trips anywhere on the mighty Colorado River. They provide half-day and full day tours that are perfect for the entire family (kids aged 4 and up). Departing from the scenic town of Page, Arizona, your trip will begin with an exciting and exclusive ride down the two-mile long Glen Canyon Dam access tunnel. At river level, Glen Canyon Dam soars 700 feet above you, where you will board a comfortable pontoon raft for your journey downstream. For the next 3 hours, you will experience one of the most dramatic stretches of river in the western United States. Your experienced guide will tell the story of the area’s soaring sandstone cliffs, crystal blue-green waters, abundant wildlife, exploration by Major John Wesley Powell and others. You will learn more about the river’s modern role in the Southwest’s water and power delivery system.
