Playa Hundu is a quiet shore-entry reef near Santa Martha, reached by a small dirt road and a short swim from the beach. The reef begins shallow and slopes away into a healthy coral garden before giving way to sand farther out. It is a low-key, clear-water site where stingrays rest in the sand, flamingo tongue snails are often seen on the reef, and moray eels also show up along the slope. The best visits feel unhurried, with calm water, limited parking, and a surface buoy carried from shore.
