Take a cycling tour of one of the better kept ruins of ancient Ceylon - the UNESCO World Heritage City of Polonnaruwa, which was the medieval capital of Sri Lanka. You will be cycling about 10km on soft surfaces as you whizz between the ruins. The ancient heart of Sri Lanka. An important royal capital with its well-preserved 12th century ruins & impressive stone culture recalls an inspired past. Although nearly 1000 years old, it is much younger than Anuradhapura and generally in better repair. The monuments are arranged in a reasonably compact garden setting and their development is easier to follow.
