The beautiful white beaches of the National Park are an idyllic place to spend the afternoon in and out of the warm Caribbean Sea. In 1996 they were given a Blue Flag Ecological Award, and although itâ€™s very inviting, please heed the precautions outlined at both entrances to the park. Rip-tides are very common in Costa Rica, and the first 1.5km of Playa Blanca, coming from the Cahuita entrance, is officially a dangerous swimming zone; note the red flag present on the beach. Further along the coast, after the river Suarez, the sea is safer for swimming. Look out for the green flags. Take note that there are no lifeguards on the parkâ€™s beaches.
