Diving among clouds of krill along the Ningaloo Reef, a whale shark swims with its mouth wide open, feeding on hundreds of the tiny sea creatures. Nearby, a boat load of snorkellers watch on, amazed at the grace and docility of this giant creature.

Swimming with the world's largest fish is just one of the awesome experiences available in the north west of Western Australia. For many visitors, it is a once in a lifetime thrill.

Coral Bay is the southern gateway to the Ningaloo Reef and offers an idyllic family holiday. The calm sandy beaches are perfect for swimming, while just 20 metres from shore lies the State's largest coral reef and a large variety of colourful tropical fish. Snorkelling equipment is available for hire from nearby dive shops, or there are glass bottom boats operating daily tours. Snorkelling and scuba diving cruises to the outer reef are also available.

March is a good time to visit Coral Bay, if for no other reason than to witness the unique natural phenomena of coral spawning. This event takes place over three nights beginning a week or so after the full moon during March and April.

Each night, many species of coral suddenly release millions of bright pink egg and sperm bundles which float to the surface of the water, as though engaging in a spectacular underwater dance.

It's little wonder that the awesome fishing conditions attract a large number of visitors. Beach fishing areas are easy to get to, while deep sea and game fishing charters are available. Coral Bay relies heavily on tourism and offers all levels of accommodation from caravan and camping to resort style apartments overlooking the beach.

Just 150 kilometres to the north is the larger town of Exmouth, a great base from which to explore the nearby marine and land based natural attractions. As the northern gateway to the Ningaloo Marine Park, Exmouth boasts diving and snorkelling conditions that have been rated amongst the world's best. Like Coral Bay, there are plenty of snorkelling, diving and fishing tours available, as well as many calm and sheltered swimming beaches.

To the south of the town is the amazing Cape Range National Park where you can experience spectacular gorges, in season wildflowers and amazing wildlife. There are four wheel drive tours available from Exmouth or the adventurous can camp or stay in unique safari style accommodation. Be prepared to pay entry and camping fees.
