Bathu Ki Ladi is a group of medieval Hindu temples that normally rest beneath the surface of the Pong Dam reservoir. They were built during the Pratihara period (roughly 8th–9th century AD) in the valley floor that was later flooded when the dam was constructed in 1974. The village they served was relocated, but the temples were left in situ.
Each year between roughly March and June, as the reservoir level drops due to irrigation releases, the tops of the temple towers emerge from the water — sometimes just the spires, sometimes the full upper sections of the shrines, depending on the water level. The gradual emergence creates an otherworldly visual: temple towers rising from a flat expanse of water with the Shivalik hills behind them. Boats can be hired from the nearby shore to approach the temples during the emergence period. The timing varies by year and depends on dam management, so it is worth checking locally before making the trip specifically for this sight.
