List of summer colonies

The term summer colony is often used, particularly in the United States and Canada, to describe well-known resorts and upper-class enclaves, typically located near the ocean or mountains of New England or the Great Lakes. Many of these historic communities are considered quiet bastions of old money, though some, such as The Hamptons, are now well known for their celebrity-driven social scenes. Additionally, their economies tend to be driven largely by this tourist trade, particularly those communities that are remote or on islands.
