Amazing hostel in the Swiss Alps about 1h (by train) east of the French border. It's called Challet Martin and in is in a town called Gryon.
They orgainze activites and outtings, movie nights, and BBQs. It was my first hosteling experience and I had the best time. If you are there, don't pass up the oppertunity to go to the thermal baths!

P.S. Plan for an extended stay.
