I recently visited sukhna lake in chandigarh and was quite please with the experience.
To start with there is safe car parking(charges rs 20) just in front of the lake.
As u enter lake ur welcomes with a citco managed restaurant,souvenior shop and fast food
Softy costs rupees 35 though of very good quality
There are lots and lots of rides for small kids like
train, musical cars,bouncers etc
The best part of the lake is the jogging track made side to lake u can take a long walk besides the lake and watch people doing boating inside
There is a small island made in middle of lake and u can see the coast guard flag on that
Most of the boats are manually pedaled boats .
There are few painters sitting on lake who sketch u in 10/15 minutes(charges rs 100) but its worth that
They give u small stool to sit and sketch u
Some bikes are avilable on rent to go for biking nearby
Its a very clean area with governor of haryana and punjab residences next to it.
Recommended place to hang out with family,friends and small kids
Must watch for every visitor
