Ahmedabad is a world heritage city, 600 years old! Kankaria lake is one of those historical, memorable place to visit, The lake is huge with an artificial Island in beetween, which was known earlier as "Wadi-e-Nagina", Simplified as Nagina Wadi, where king ShahJahan ( Then a Prince) met Mumtaz for the first time in the middle of the lake, and romance began!
The lake has been totally renovated, with a joy train round the lake, Baal-Vatika(Kids Garden) , many kids and adventurus rides, hot air baloon and an Air conditioned "Kids City". In the morning it's nice place to go for jogging. As ahmedabad summers are hot winter is a beautiful season to visit. You can also hv a boat ride in the lake. Though the place is in the middle of a textile city, it is totally pollution free.
