Sri Lanka’s largest national park is built around a series of naturally formed lake basins called villus that draw extraordinary concentrations of wildlife to their edges in a landscape of remarkable silence and genuine wildness. Wilpattu receives far fewer visitors than Yala, which means the leopards here show more natural, undisturbed behaviour, the sloth bear encounters feel genuinely wild rather than managed, and the quality of the wilderness experience is consistently higher for travellers who value depth of encounter over sighting frequency.
