The one constant theme surrounding fall foliage in New England is: BOOK YOUR HOTEL EARLY. More than anything, this is critical because it is the only way you will have a choice of where to stay. Prices rise from mid-September to the end of October and supply often does not meet demand.
Boston is a great starting point for day trips in Massachusetts, Rhode Island, and parts of New Hampshire. There are also plenty of other places to stay; Providence, R.I., for example, is only 40 miles south; Worcester, MA is inland about an hour's drive from Boston and central to the Berkshires to the west, Connecticut to the south, and New Hampshire to the north. Old Sturbridge Village in the area is a must-visit.
Information about peak leaf-peeping season is readily available. There are several sources, including telephone hotlines and a multitude of Web sites.
