Corbett National Park is India's first national park. The park get's its name from the famous hunter turned conservationist - Jim Corbett who spent a large part of his life in the region. The Park's location (foothills) is prime as it offers a right of passage for several species of birds in their annual migration from the higher reaches of the Himalayas.
Located in the Shivalik foothills of the Himalayas. The Park is demarcated in to several zones that visitors can visit on a day safari and / or night stay. These zones are Dhikala, Jhirna, Bijrani, Dhela, Sonanadi, Gargia, Pakhro and Durgadevi
Out of the five zones in Corbett, Dhikala and Bijrani are the most sought after. Dhikala is the biggest zone and the landscape and natural habitat is believed to support the highest density of tigers due to abundance in prey base. It's expansive grasslands support herds of elephants and other herbivores including the Indian hog deer. The Ramganga river flows through the zone and is home to not only the Indian marsh crocodile but also gharials and smooth coated otters.
Corbett is also a very attractive bird watching destinatio and  known to have over 500 avian species that come and go during various seasons.
