Wakatobi

Wakatobi holds the world record for the highest number of reef and fish species ever recorded in a single area—942 species, as documented by Operation Wallacea. Its pristine fringing reefs boast a coral cover exceeding 85%, which is 30% higher than the average Indonesian marine park. This biodiversity outperforms #1 Raja Ampat's 1,374 species when adjusted for area, making Wakatobi the most species-dense reef system globally. Divers enjoy consistent 30-meter visibility and minimal currents, ideal for relaxed, data-rich exploration.
