Hostelling International - New England manages six youth hostels in Boston, Cape Cod, the town of Harvard in Central Massachusetts and on the islands of Martha's Vineyard and Nantucket.
A new "green-designed" and energy-efficient hostel in Boston opened in 2012. Located in the heart of Chinatown and the Theatre District, the hostel is a short walk from Amtrak's South Station. It offers a new group kitchen and dining room, community room, 480 beds including more than 20 semi-private rooms.
Hostelling International's three hostels on Cape Cod are located in Hyannis, close to the ferries that go to Martha's Vineyard and Nantucket; in Eastham, just above the elbow of the Cape, and in Truro, offering private access to the beautiful sandy beaches of the Atlantic Ocean.
There are loads of other affordable options in all parts of the state, as well from motels to small bed and breakfasts. Check out the state tourism website at www.massvacation.com/find/lodging to do a complete search.
Campgrounds are also fairly easy to find across the state. In summer and early fall, especially on weekends, it's best to make reservations several weeks in advance. For more information here, go to the Massachusetts Association of Campground Owners website: www.campmass.com.
