An inexpensive, supervised place for young travelers to stay overnight.
Example:
Generations of American college students have traveled through Europe cheaply by staying at hostels instead of hotels.
Throughout Europe and in some other parts of the world, a network of youth hostels provide cheap, safe (although not always quiet) overnight shelter for younger bicyclists, hikers, and canoeists. The United States has over 200 youth hostels, many of them in New England. Worldwide, there are more than 5,000.
