Great Barrier Reef

Introduction
The Great Barrier Reef is the world's largest coral reef system, stretching about 2,300 km, made of thousands of coral reefs and islands, the only living structure visible to the naked eye from space, listed as a World Natural Heritage site in 1981. Cairns is the main gateway to the Great Barrier Reef; from here a cruise takes about one to two hours to reach the outer reef, where you snorkel or dive among colorful coral gardens, swimming with tropical fish, turtles and manta rays, or view the underwater world from a semi-submarine or glass-bottom boat. Protecting this fragile, magnificent underwater wonder is the responsibility of every visitor.

Any practical tips for visiting Great Barrier Reef?
Choose an outer-reef trip; corals and fish are more spectacular than near shore. Use reef-safe sunscreen, do not touch coral; protect the fragile ecosystem.
