Lake Powell is formed in the Colorado River by the Glen Canyon Dam, just upstream of the Grand Canyon. Lake Powell offers opportunities for swimming, kayaking, and boating - a rarity in the desert. The surrounding canyon includes hiking trails with arches, hoodoos, and beautiful striped rocks. Rent a kayak or house boat, watch the sunset at Horseshoe Bend, explore the Hanging Gardens and New Wave, swim or hike at the Chains, or take a boat tour (tour options include a trek out to Rainbow Arch). Glen Canyon is a beautiful section of canyon along the Colorado River without the crowds of the Grand Canyon.
