Antelope Canyon stands as the world's most photographed slot canyon, located on Arizona's Navajo Nation near Page. The canyon comprises two distinct sections: Upper Antelope Canyon featuring above-ground slot passages with iconic 'light beams' and Lower Antelope Canyon requiring ladder descents through underground passages. Formed through millions of years of flash flood erosion through Navajo sandstone, the canyon displays colors ranging from warm oranges and reds to deep purples and shadows. Light beams visible during specific seasons create ethereal columns of light - images circulated globally through photography and social media. All visits require Navajo guides; tourism benefits local communities and respects the canyon's sacred significance.
