The state's signature
Whale season on Stellwagen Bank
An underwater plateau at the mouth of Massachusetts Bay concentrates sand lance — and the humpbacks, finbacks and minkes that eat them — into one of the Atlantic's most reliable whale grounds. Season language only: the bank feeds, it doesn't promise.
Seasonal RV-timing verdict
When Massachusetts is at its best
Massachusetts's prime RV window is May to October. Pleasant summers and spectacular fall foliage; winters are cold with nor'easters bringing snow and coastal flooding. Shoulder-season play: April and November offer lower rates but spring mud season and early snow can complicate travel.
Know before you go
Cape Cod traffic is heavy in summer. Winter nor'easters can close roads and campgrounds.
