While most of our earliest memories of holidays are with our parents, and what blissful memories they are, travelling becomes a process of learning as we grow older. As kids, we enjoyed nothing more than heading out of the city to sample the sights, bites and uniqueness of new lands. As we get older however, it becomes important to experience new places on your own or with your friends for several reasons. Some spots will scandalise, some will give them heart problems and some places are just best enjoyed alone, so for everyone's sake, leave your folks out of it!
Go snowboarding, get a license to teach skiing and become an undercover secret agent (I'm just kidding about that last part) without giving your parents any cause for concern.
You just can't overstate the beauty of these Himachali hot spots. It is, however, best avoided by parents as the trek is long and arduous and the sights, though heavenly, are interspersed with people going "boom" and smoking unmentionables.
