Lonely Planet's Cape Cod, Nantucket & Martha's Vineyard guide describes the Stoney Brook Grist Mill thusly: "This town-owned mill is one of the Cape's lushest and most tranquil spots. The water wheel still turns the machinery that grinds cornmeal, and a small museum has Brewster memorabilia.
Try to visit the adjacent open-air Herring Run during the time when thousands of herring migrate from the ocean to fresh water in order to spawn in the pond above the mill. Dates change annually, but mid-April to mid-May is a good bet."
