Welcome to the incredible ancient city of Polonnaruwa, a sprawling UNESCO World Heritage site that feels like stepping into a lost kingdom. The best way to soak it all in is by renting a bicycle and pedaling at your own pace through the well-preserved ruins of palaces, temples, and magnificent stupas. You'll be in awe of the four colossal Buddha statues carved directly into the granite rock at Gal Vihara. The site is vast but wonderfully peaceful, allowing you to connect with Sri Lanka's rich history without the huge crowds.
