Close to the M.G.Road this lake is one of the main attractions of the holiday goers in the city. With a radius of about 3-Km, this lake is ideal for rowing around in a boat or to sprawl on the green grass that surrounds the lake. People could also sit and relax on the small islands that are on the lake.

The Ulsoor Lake or Tank (once called the Ulsur Lake) lies to the North-West of Ulsoor. The lake is quite dangerous to swim in and there are many a European Soldier who has drowned in the same, perhaps caught in the weeds and lotus plants. J.W. Morris in the 'Guide to Bangalore and Mysore Directory 1905' describes the Ulsoor Lake saying that for some time the condition of the Lake was regarded as dangerous to public health because of the weed-choked and shallow waters. In 1901, the water level came very low, and the Lake was drained, and the weeds were removed before the monsoon. The whole operation of draining and rooting out the weeds took around 30 days. When full, the lake is about 125 acres; it's greatest depth was around 11' to 12' , with an average of 8' all around. earlier the water-works for supplying the European Troops were situated on the side of a rock adjoining, but with the introduction of piped water supply, this was disused.
