Spot Guide
Mansion Beach is a scenic stretch of shoreline on Block Island, Rhode Island, facing west-northwest into Block Island Sound and offering fun, punchy beach break when south swells wrap around the island's southern tip. The unique geography of Block Island means this spot picks up long-period S and SSW swells that refract around the coast, producing surprisingly consistent peaks with good shape for intermediate surfers. Its relative remoteness — requiring a ferry ride from the Rhode Island mainland — keeps crowds manageable and adds to the adventure of scoring it on the right day.
