Great Barrier Reef: A kingdom of coral and a breathing blue

The Great Barrier Reef is the largest coral reef group in the world, visible from space. Five days and four nights, between coral and azure, you encounter a breathing sea.

Starting from Cairns, the island hop features coral gardens beneath the glass-glass boats, with clownfish, sea turtles, and brain corals each taking their place. This "living" blue is one of the lungs of the Earth.

Snorkeling or deep diving, drilling into coral tunnels, beams of light slanting from the water, and schools of fish circling around you. First-time swimmers are often so stunned they forget to breathe.

From the plane, you can overlook Heart-shaped Reef, where the natural heart-shaped coral reef is nestled between blue and green—a paradise for proposals and awe. The romance of nature requires no design.

Green Island and Fitzroy each have rainforests and white sands; walking to the lighthouse, the entire reef area is paved with turquoise beneath your feet.

The crispness of the fort is a warning that even beauty is written as a warning. When you touch the warm seawater and think of albinism, you will understand: some miracles require our gentle protection.
