There are no permanent inhabitants of the islets or reefs. Fishermen visit the area seasonally, establishing shelters on the islets. The park is visited by tourists, particularly divers. Trips to Tubbattaha from mid-March to mid-June are all vessel-based; the park is about twelve hours by boat from Puerto Princesa City. Tubbataha is considered as the best dive site in the Philippines and the diving dedicated ships that operate during the "Tubbataha Season" are usually booked years in advance especially during the Asian holidays of Easter and "Golden Week".
Tubbataha has become a popular site for seasoned sports divers because of its coral "walls" where the shallow coral reef abruptly ends giving way to great depths. These "walls" are not only wonderful diving spots but they are also wonderful habitats for many colonies of fish. Over 1000 species inhabit in the reef; many are already considered as endangered. Animal species found include sea turtles, manta rays, sharks, lion fish, barracudas, Moorish idols, clown fish, dolphins, whales etc. Aside from being a marine sanctuary, Tubbataha is also renowned for being a bird sanctuary. A lighthouse islet, at the southern tip of the South Atoll, supports a large number of seabirds which nest there. Around the Tubbataha, there are tens of thousands of masked red-foot boobies, terns, and frigate birds resting during their annual migrations. This is a World Heritage Site by UNESCO. One of the most beautiful reef around the world.
