Kankaria Lake, formerly known as Hauz e Qutub, is the second largest lake in Ahmedabad, Gujarat, India. It is located in the south-eastern part of the city, in the Maninagar area. A lakefront is developed around it, which has many public attractions such as a zoo, toy train, kids city, tethered balloon ride, water rides, water park, food stalls, and entertainment facilities.

Kankaria Lake was built by Sultan Qutbuddin in the 15th century. The work was completed in 1451 CE and was known as “Qutb Hauz” or “Hauz-i-Qutb”. It was used for bathing by the kings. It had a water purification system but it has been lost with the time. At one point of the circular lake, there opens a walkway which later merges into a garden called Nagina Wadi (which means beautiful garden in Urdu) that is located in the centre of the lake. With an approximate circumference of 3 miles (4.8 km), it represents the regale history of Ahmedabad. It is a 34-sided polygon having steps which leading down to water level.
Renovation

The central garden and the walkway had been revamped and utilities are enhanced. Upon completion of the renovation the lake was officially inaugurated in a week long event known as “Kankaria Carnival”. The inauguration ceremony for renovated Kankaria lakefront was held on 25 December 2008.
