Lake Saif-ul-Malook of Pakistan, i have visited here few months ago, it was really awesome place and really cool and neat water. A story about this lake is that a fairy dance on the surface of water at mid night of moon 14th every month. People told me that they have seen them many time. Overall a beautiful place for picnic point of view.
