Bathtub Beach, Protected beach in Martin County, United States.
Bathtub Beach is a protected beach in Martin County featuring a natural limestone reef formation that creates sheltered waters with calm conditions. The shallow, clear water is shielded from stronger waves by the reef structure, making it accessible for swimmers of all ages and abilities.
The beach received its name in the early 20th century when local residents noticed the calm waters resembled those of a bathtub. The protective reef was already recognized at that time as the defining feature that made the location special and valuable for swimmers.
The beach draws school groups and nature enthusiasts who come to explore the reef ecosystem and learn about marine life in its natural setting. Visitors can observe coastal nature firsthand and understand how the natural structures protect the shoreline.
The beach is open daily and provides parking and restroom facilities for visitors. Check the hours of operation and ask at the visitor center about current water conditions, especially during storm seasons.
The reef structure is built by tiny Sabellariid worms that cement sand grains together to form protective tubes, creating a natural breakwater system. This biological engineering is barely visible to the naked eye but plays a critical role in keeping the entire beach stable and sheltered.
