Just south of Playa del Carmen you'll find Puerto Aventuras, which literally means ‘port of adventure' – and you're in for one on this day out. You'll begin with a Royal Swim experience, where you'll learn about these beautiful creatures before you interact with two dolphins and see beautiful manatees, too. Then, you'll head out into those famously blue Caribbean waters for a laidback catamaran cruise – by the way, your lunch and drinks on board are included.
