For those who leave the snorkel behind and prefer to dive meters down: welcome to the Costa Tropical. Around La Herradura and Punta de la Mona awaits an underwater world that will (and should) make you quiet. Caves, schools of brightly colored fish and maybe an octopus peeking at you on the sly. Beginners can visit one of the many diving schools for a first dive; advanced divers just go on their own. Whether you come to practice or discover - this is going deep in the best sense of the word.
