The Udawalawe National Park stretches over 190 square kilometres of light, arid scrubland. There is very little forest cover in the park, but it is still home to a large number of species including Toque macaques and grey langurs, giant flying squirrels, crocodiles, jackals, wild boar, fishing cats, sloth bears, deer and leopards. The park is particularly popular for its elephants, with many herds usually seen in close quarters, and is an important habitat for the country's waterbird populations. As with most of the terrestrial national parks in the country, it's best to visit the park either during the early hours of the morning or during the evening.
