Finding a cheap hostel in the Alps, maybe booking in French?

I have been to Chamonix and Les Arcs want to try somewhere else with a youth hostel any recommendations? Are youth hostels in French- auberge jeunnesse? And if I was to book a dorm room in one how would I say in French - could i have a dorm room for one person from 16th march to 22 of march please. And is breakfast included/
