Great Barrier Reef

Here's why Great Barrier Reef might be calling you:

Your bucket-list adventure is the Great Barrier Reef: the world's largest coral reef system, off the coast of Queensland, Australia. Snorkelling or diving here means turtles, rays, clownfish and coral in every color imaginable.

It suits your love of adventure and your sense of wonder. You want to see something truly alive and extraordinary, and you're happy to jump right in.

The flip side: the reef is fragile. Choose eco-certified tours, wear reef-safe sunscreen and look, don't touch. That way it'll be amazing for everyone who comes after you.
