The Colony Hotel, Kennebunkport, Maine

Although nearly a century old, this New England classic can teach eco-upstarts a thing or two. Guests drawn by sweeping Atlantic views, the heated saltwater pool, and a private beach also get organic foods and a nature education program.
Eco cred: The Colony composts waste and has banned plastic foam containers, aerosol sprays, and plastic bin liners. Trash baskets in each room have four compartments, allowing guests to sort recyclables.
Insider’s tip: Pick up a recycled souvenir. The hotel turns worn bedspreads and linens into handcrafted dog blankets.
