The highlight of Wilpattu National Park is its Willus—natural sand-rimmed depressions that collect rainwater. The lakes are distributed over the park and offer lifelines to wildlife during drought. Elephants, leopards, deer, wild boar, and groups of waterbirds visit the lakes. Watching animals gather at a villu gives you an authentic wilderness experience and excellent photography.
The Willus constitute the core of Wilpattu's ecosystem and attract countless animals and birds. Spending time at lakes like Borupan Wila or Thalawila Villu gives you peaceful moments as you watch elephants bath, crocodiles soak in the sun, or flocks of migratory birds feeding in shallow water.
