Surfside Beach.

Surfside Beach is the quintessential South Shore destination, defined by its wide, flat expanse of sand and consistent rolling waves. Located three miles from town at the end of a dedicated bike path, it draws a high-energy crowd ranging from families to surfcasting enthusiasts. The beach is unique for its accessibility; while many Nantucket shorelines require a 4x4 vehicle, Surfside offers a large parking lot, seasonal shuttle service, and full amenities including restrooms and showers. The water here is lively, with sandbars that create ideal conditions for bodyboarding and surfing, while the deep troughs further out attract anglers looking for Striped Bass. A central snack bar serves as a local hub for grilled food and refreshments, providing a convenient alternative to packing a cooler. Despite its popularity, the shoreline is vast enough to accommodate massive beach games and quiet picnics among the dunes.
