🐠 Great Barrier Reef

Cairns, Australia

Best time: June to October, the dry season, with clear water and no stingers

The world's largest coral reef system, stretching over 2,000 km and visible from space. Snorkel or dive among coral gardens, turtles and clouds of tropical fish.

Good to know

• Take a boat from Cairns or Port Douglas to the outer reef, where the coral is in better shape.
• From November to May, wear a stinger suit in the water.
