youth hostels association of india

You must be referring to something like Summer camps in the west. I know what they must be like from the films Kuch Kuch Hota Hai where Angalie went to a camp and Krish where some youth are on a hill climbing expedition. In Sri Lanka we don't have them but there are plenty of activities arranged and sponsored by some companies. But India being a big country there is enough to explore. So become a member, and hurry.
