While there are many national parks in Sri Lanka, Yala is easily one of the most popular for one very good reason; it is known for having the highest leopard density on the planet and is where you can see these majestic predators roam wild and free. Of course, leopards are not the only creature you have a chance of spotting in Yala. On your safaris at this sanctuary, you may also come across elephants, crocodiles, sloth bears, water buffaloes, fishing cats and toque macaques, not forgetting a great many bird species too.
