This vast reserve, stretching over 750 square kilometres of densely forested terrain in the Cardomom Hills, does have a few tigers and leopards, but they are rarely seen out of the dry season in April and May and even then sightings are rare. However, its lake (which offers boat trips) attracts thousands of birds, and sightings of elephants, sambar and bison are frequent. There are also Malabar giant squirrels, striped mongeese and wild boar.
