The Yala National Park is best known for spotting leopards. It is located in the south-east coast of Sri Lanka and would take about 5 hours to drive from Colombo to Yala comfortably. It is the premium national park in the island and most tend to think that it is also the best to spot mammals in Asia. You get to spot leopards, sloth bears and other animals such as toque monkey, buffalos, ruddy mongooses, langur monkeys and wild pigs in their natural habitat. The leopard which is a sub-species endemic is the most sought after sighting in this part of Sri Lanka. Tour operators are bound to include Yala in the itinerary if you mention that you would like to visit a national park.
