If you are a nature lover, you must visit to the Indian Botanical Garden at Shibpur. Today known as the Acharya Jagadish Chandra Bose Botanical Garden, it was founded in 1787, and at present you can find a huge variety of rare plants here. The main attraction of this garden is a banyan tree which is among the the largest tree in the world.

Take a boat ride
Cruise down to Sunderban through the Hooghly. Calcutta was built on either side of the river. You can see old buildings, small towns on the banks through the cruise. Deep Dasgupta
Visit the north-east
The north-east of the country has some of the prettiest places not only India, but perhaps the whole world: places like Darjeeling, Kalimpong, Gangtok and Shillong. Darjeeling and Kalimpong offer stunning views of Kanchenjunga and Everest. You have to take two days off and go to one of these places in the north-east, and enjoy the lifestyle, language, culture. It will be laidback, will give you a couple of days off the hectic schedule, and you will love having spent time there. Deep Dasgupta
