I am from Delhi and have a few days where I can take my family out for a holiday. We preferably would like to go to a hill station where the weather would be much clearer and the weather would be pleasant. As we would not have many days for our holiday, we would like to go to the nearest hill station from Delhi. I need to know which one this is, and exactly how long it would take to reach the hill station? Would it be safe to travel at night to the mentioned hill station, so it would give us some extra time at the hill station destination?
