If you want to see the chandigarh or going for a tour in chandigarh than you need to go to sukhna lake its one of the best place in chandigarh but from the last few years I dont know what is affecting the sukhna lake maybe it is my thinking because I visited sulkna lake many times and now I did not have any interest to see or visit sukhna lake but if you are new in chandigarh or visiting sukhana lake for 1st time than go its very beautiful
