Accessed primarily by steamship, Mt. Kineo House was a thriving summer resort for the wealthy set below its namesake's 800-foot cliff on an island-like peninsula north of Greenville. The last of three successive hotels with this name was built in 1884 and became America's largest inland waterfront hotel. It was torn down in 1938, but Kineo remains a pleasant day trip. There's no road access: take a 15-minute boat trip from Rockwood on the seasonal shuttle. Mt. Kineo State
Park occupies most of the 1,200-acre peninsula, and you can also play a round on the Mt. Kineo Golf Course, one of the oldest in New England.
