Minneriya National Park is situated in the north-central plains of Sri Lanka, 20 kilometers from Polonnaruwa. The park encompasses the beautiful Minneriya tank, built by King Mahasena (in 3rd century AD). This tank is an incredible place to observe the elephants that come to bathe and graze on the grasses as well as the huge flocks of birds (cormorants, painted storks, open-bills, Pelicans and many other species of waders) that come to fish in the shallow waters.
