Top 10 Most Beautiful Coral Reefs

This remote archipelago in West Papua contains the highest marine biodiversity ever recorded, with over 1,500 fish species and 75 percent of all known coral species concentrated in its waters.

The second-largest barrier reef in the world stretches 1,000 kilometres across four countries, anchored by Belize's iconic Great Blue Hole, a giant marine sinkhole visible from space.

Uniquely heat-tolerant corals thrive in waters that would bleach reefs elsewhere, making the Red Sea a potential refuge for coral species as ocean temperatures rise globally.

This UNESCO site in the Sulu Sea is accessible only by liveaboard during a brief annual season, protecting pristine walls that plunge hundreds of metres and teem with sharks, mantas, and turtles.

Western Australia's 300-kilometre fringing reef is one of the few large reefs accessible directly from shore, famous for annual whale shark aggregations from March to July.

One of the most remote and pristine coral atolls on Earth, Aldabra is home to 100,000 giant tortoises and coral ecosystems largely untouched by human activity.

Part of the Mesoamerican reef system, Cozumel's Palancar reef offers towering coral pillars, dramatic swim-throughs, and visibility exceeding 30 metres in crystal-clear Caribbean waters.

Located in Southeast Sulawesi, this national park encompasses one of the highest-diversity reef systems in the world, with over 750 coral species documented across its four main islands.

The largest contiguous coral reef system in the Philippines covers 34 square kilometres in the Mindoro Strait and supports an extraordinary density of marine life despite limited tourism infrastructure.
