Going to Shimla with friends, but don't know what to do there, here are the best ways that i think-

1. OK, Shimla is Hillstation So GO skiing.

2. Is there snow? play with the snow, make a snowman.

3. Go sightseeing, try having a whole day tour of the city.

4. Click LOTS  of pictures, to show how much you enjoyed your trip

5. Do NOT  get bored just have fun! :)
