Falmouth has shoreline on Buzzards Bay to the west and Vineyard Sound to the south, and the difference is not subtle.
Old Silver Beach in North Falmouth faces north-west into Buzzards Bay. Shallow, warm, a sandbar at low tide that toddlers wade on, and a sunset that goes down over the water rather than behind you. It is the most popular beach in the town and its lot fills on a hot day.
Falmouth Heights Beach faces south into Vineyard Sound with Martha's Vineyard visible across the water and the ferries passing. Calm, family-oriented, and busy.
Surf Drive Beach is close to the centre, easy to reach on the bikeway, and the most practical if you are without a car.
Menauhant and Bristol Beach on the south shore are quieter alternatives.
Chapoquoit in West Falmouth is the local's choice on Buzzards Bay, with a reputation for wind that makes it a kite and windsurf spot.
Town beach parking requires a Falmouth sticker in season, sold to non-residents by the town in periods that change from year to year. Some lots take a daily fee. Check the current arrangement.
None of this is Atlantic water. There is no surf here, the water is comparatively warm by August, and the shark advisories that govern the Outer Cape do not apply on this coast in the same way. For families with small children, this is the easiest swimming on Cape Cod.
