10. Ayutthaya, Thailand

Ayutthaya, once a vibrant hub for international travelers, now stands in quiet contrast to its former bustle. With global arrivals at historic lows and local tourism yet to rebound, the city’s sprawling temple ruins and crumbling stupas are nearly deserted. This newfound emptiness offers visitors a rare opportunity to wander through the UNESCO World Heritage Site in peace, immersing themselves in its rich history without interruption (Bangkok Post).
