Its karan lake not karnal lake. It is situated outside the city. When I visited this place there is not too much rush but I heard about this that there is mostly no rush. I visited in evening.it was cloudy weather. There is a cafeteria which has almost all facilities at reasonable rates. We did boating there. Its feels so awesome in evening while boating. But water is not clean, it is polluted water, somewhere polythene or other plastic bags. Local people are not so much good the are irritating and behaves like illiterate. If remove these things its good place to visit in evening. Very calm and plants are All around.
