The largest national park in the country, The unique feature of this park is the existence of “Willus” (Natural lakes) - Natural, sand-rimmed water basins or depressions that fill with rainwater. Located in the Northwest coast lowland dry zone of Sri Lanka. The park is located 30km west Anuradhapura and located 26 km north of Puttalam (approximately 180 km north of Colombo).

The park is 131, 693 hectares and ranges from 0 to 152 meters above sea level. Nearly sixty lakes (Willu) and tanks are found spread throughout Wilpattu. Wilpattu is one of the largest and oldest National Parks in Sri Lanka. Wilpattu is among the top national parks world renowned for its Leopard (Panthera pardus kotiya) population. The Leopard population in Wilpattu is still not yet known.

Its flora...

There are many Villu and lakes at Wilpattu. This is identified as the main topographical feature of the Park. They are often flat and basin like while containing purely rain water.The western sector of Wilpattu is covered deeply with forests. Many species of flora can be identified at Wilpattu national park. There are three types of vegetation; Littoral vegetation, including Salt grass and low scrub immediately adjacent to the beach and further inland, monsoon forest with tall emergents, such as Palu (Manilkara hexandra), and Satin (Chloroxylon swietenia), Milla (Vitex altissima), Weera (Drypetes sepiaria), Ebony (Disopyros ebenum) and Wewarna ( Alseodaphne semecapriflolia).

The fauna...

Looking at the fauna of this national park mammalian diversity and ecological densities are highest. A total of 31 species of mammals have been identified at the Wilpattu national park .We witness many kinds of birds flying about at the Wilpattu. The Villus support both resident and migratory water fowl, including large breeding populations of the Painted stork (Mycteria leucocephala) and Open billed stork ( Anastomus oscitans).

Other wetland bird species as Garganey (Anas querquedula), Pin tail (Anas acuta), Whistling teal (Dendrocygna javanica), Spoonbill (Platalea leucorodia), White ibis (Threskiornis malanocephalus), Large white egret (Egretta alba modesta), Cattle egret (Bubulcus ibis) and Purple heron (Ardea purpurea) also found at the Wilpattu National Park.

At Wilpattu, among the reptiles found the most common are the Monitor (Varanus bengalensis), Mugger crocodile (Crocodylus palustris), Common cobra (Naja naja), Rat snake (Ptyas mucosus), Indian python (Python molurus), Pond turtle (Melanonchelys trijuga) and the Soft shelled turtle (Lissemys punctata) who are resident in the large permanent Villus. We can saw Star tortoises (Geochelone elegans) roaming on the grasslands at Wilpattu. Termites of the Genus Trinervitermes clan probably account for the most significant proportion of the invertebrate bio mass. Termites are found not on the grasslands but actively living in the scrub forests.
