Sipadan Diving, Sabah

Sipadan Island ranks among the top five dive sites globally, justified by marine life density along vertical walls — thousands of barracuda and jackfish, green and hawksbill turtles at every site, and a channel passage that fills with hammerhead sharks on early mornings. The strict 120-diver-per-day permit system ensures uncrowded dives, costing $150 per permit, which is 40% cheaper than the average rival dive site in the Maldives. It outperforms #3 Kinabatangan's river tours in marine diversity, with 60% of dives encountering turtles. Depths drop to 2,000 metres near the wall, a key measurement. Comparisons show it's more isolated than #1's Mount Kinabalu but offers year-round visibility of 20 metres, making it a bucket-list destination for underwater enthusiasts.
