There are several bays near the small town of Akumal. This is the closest so it makes sense to call it Akumal Bay. To the north is Half Moon Bay and further up is Yal Ku Lagoon. Both are excellent for snorkeling. To the south is Jade Bay. You might also enjoy swimming in the 75° degree waters of Tak Be Ha, a cenote called the Palace of Hidden Wonders. So much beauty and so little time.
