Kolkata not only has some good public transport system, but their beautiful and nostalgic vehicles will make you drop the idea of exploring the city by tourist vehicles. Kolkata Tram, Underground Metro, Ferries and Blue Minibuses are enough to fill your mind with nostalgia. Do hop into the ferry at Hoogly River to witness the magnificent Howrah Bridge.
