Just 14 kilometers from Kaza, the Key Monastery (also spelled Ki or Kee) sits majestically atop a hill overlooking the Spiti River. This thousand-year-old Tibetan Buddhist monastery is the largest in Spiti and home to hundreds of monks. Its fortress-like architecture, white walls, and golden spire create a breathtaking sight against the stark mountain backdrop. Inside, ancient murals, prayer wheels, and scriptures preserve centuries of history and faith. The monastery also offers a panoramic view of the surrounding valley—especially enchanting during sunrise and sunset. Visitors can attend prayer sessions, interact with monks, and even stay overnight for a deeper spiritual experience. Key Monastery isn’t just a landmark—it’s the beating spiritual heart of Spiti.
