Parakrama Samudraya, or the Sea of Parakrama, was built by King Parakramabahu I. This is one of the largest reservoirs in the island and is so vast that it truly resembles the ocean. It was built by combining the reservoirs, Eramudu Weva, Topa Wewa and Dumbutula Wewa. The Sea of Parakrama takes up around 75 kilometres and is a remarkable feat of ancient engineering. The water level in the reservoir is controlled via flood gates which are opened to release water during periods of heavy rainfall. If you visit during the right time, you may be able to see the fascinating flood gates in action. During the rainy season, the lake is a quite active destination. You may see canoes drifting across the lake and plenty of birds on the hunt for fish. People can reach the water easily by climbing down the cement steps located at certain points. It is not an uncommon sight to sea locals bathing in the water, swimming and even doing their laundry. The view over the water, with the dark and mysterious forest reserve bordering the lake, creates a beautiful picture, especially at dusk. If you have chosen to stay at an accommodation option such as the Anantara Kalutara Resort or one of the many Kalutara hotels in Sri Lanka, you can easily arrange tours to view the Parakrama Samudraya as well as the many other amazing lakes scattered across the island.
