Reef tours, diving & snorkelling — plus the complete guide to the world's coral reefs.
Coral Reef Info started as a plain reference site for reef biology — what a reef is, how it forms, the fish and animals that live on it, and the threats it faces. We’ve kept that free reference guide and added real, bookable reef tours — diving, snorkelling and reef cruises across the world’s major reef destinations — so you can go from reading about a reef to actually visiting one.
Coral reef biology, zones, formation and ecology, plus the fish, corals, plants and other animals that make up a reef ecosystem — and what’s being done to protect it. Start with what are coral reefs?
Guides to the Great Barrier Reef, the Red Sea, the Caribbean, the Indo-Pacific and more — where to dive, what to expect, and how to reef-travel responsibly. See our destinations.
Reef cruises, snorkel trips and scuba dives from operators worldwide, booked through Viator — prices, reviews and availability confirmed at checkout. Browse tours.
