Located in the Northwest coast of the island, Wilpattu National Park is a wonder in its dry zone habitat.
No wildlife excursion can be truly experienced unless you go on safari and Wilpattu National Park is no stranger to expeditions thus far and you can be sure that leopards will almost always make a grand entrance here.
Jungle fowl scurrying along, peacocks on parade, a herd of spotted deer here and there, glimpses of barking deer… Crocodiles sunbathing, flycatchers catching flies and other insects, star tortoises and breathtakingly large monitor lizards, that keep you wondering what on earth they’ve been feeding on to get so big; elephants, make up only a few of the residents of Wilpattu.
Located in the Northwest coast of the island, Wilpattu National Park is a wonder in its dry zone habitat for animal and plant life. The Park is easily accessible from Anuradhapura if travelling through the north central regions or from Puttalam on the western coast. February and October and considered the best months to visit.
