Geographically located near the southern tip of Cebu, the city of Dumaguete in Negros Oriental is known to most travelers as a gateway to the Tañon Strait—the largest marine protected area in the Philippines. Home to several species of dolphins, the site is a must-visit for tourists looking to see the intelligent creatures in their natural habitat. Aside from Tañon, there’s also Apo Island, a flourishing sanctuary where snorkelers and divers can swim along sea turtles and marine wildlife. Dumaguete is waiting—all you have to do is dive in.
