Corbett is well-known and a haven for its tigers. There is plentiful prey - four kinds of deer, wild boar and other lesser animals - for them to live on. With a bit of luck, it's possible to see a tiger on the road as you enter the park and motor down to Dhikala.
Pug marks are seen in abundance on the roadsides, paths and animal trails. It's by tracing these pug marks, which bear individual characteristics, that the estimated population, which has shown a marked increase from 40 in 1972 to 90 tigers in 1984, is known. 164 Tigers in 2009.
