Having scanned through a bunch of walking tour companies, I am very glad I chose Calcutta Walks! I did the Dalhousie Square Walk.. I was in awe of the British influence and architecture throughout the city and the indepth knowledge of the city provided by none other than the amazing Anirban tour guide. I left that tour feeling more knowledgeable about Dalhousie Square, the British history in Calcutta, and just the city in general. Also, the hospitality shown by Anirban was great, truly took care of me and my needs throughout the tour. Calcutta Walks offers a variety of tours to explore and learn about this beautiful and diverse city, so I will be coming back for more!
