South of Ballygunge, the verdant escape of Rabindra Sarovar forms what is arguably Kolkata’s best park. It folds around a large central lake, whose islands harbor colonies of squawking cormorants, while colorful kingfishers perch on branches around the edge. You'll find Kolkatans jogging, rowing and meditating around the tree-shaded parkland that was once the site of an Allied Forces medical camp during WWII. Young lovebirds match the park's avian residents in numbers, and street musicians enthrall listeners with soulful tunes, mostly on weekends.
