While proceeding towards Ballygunge from Lake Gardens on the left one can observe the beauty of Rabindra Sarobar complex. Popularly known as the 'Lung of Kolkata', the place houses an artificial lake, natural forest, children's park, gardens, auditorium & a football stadium. The forests in its vicinity are more than 100 years old. In winters, the place acquires a mesmerizing charm, as thousands of exotic migratory birds arrive here. There are umpteen varieties of fish in the lake, however fishing is strictly prohibited. The fish sanctuary is actually under the cable-stayed wooden suspension bridge, on the southern flank of the forest, connecting to an island. Apart from being a family outing venue, the place is also a jogger's paradise. The only Japanese Buddhist temple of Calcutta, built by Nipponzan Myohoji, is also located on the southern border of the complex. On the west front of the lake, there are big cannons of Nawab Siraj-ud-daulah - the last independent ruler of Bengal. There are also many swimming clubs inside the Sarobar complex. The Lake is the hub of many sports activities and a number of rowing and swimming clubs can be traced within the Rabindra Sarovar compound. Rowing clubs are located to the north of this lake and swimming clubs are located to its south. The Calcutta Rowing Club (CRC), presently one of the oldest clubs in India, for promoting rowing activities in Kolkata was founded in 1858.

The Rabindra Sarovar has an undying fame attached with it for years but the glory is on a decline due to pollution and other depredation. For this reason the lake has been taken under the National Lake Conservation Plan by the government. But the lake's actual charm - the greenery and the breeze which, by far, remains unpolluted.
