World Heritage Shark Bay | To Shell Beach, Stromatolites, and the Paradise of Dugongs

Shark Bay in Western Australia is a World Heritage site located about 700 km north of Perth. It is a notable destination for its stromatolites—believed to be the oldest life forms on Earth—and Shell Beach, which is entirely covered with tiny white shells as far as the eye can see. It's also known as the world’s largest habitat for dugongs. Let’s explore the enchanting beauty and unique features of Shark Bay, a mystical World Heritage site.

What is Shark Bay in Western Australia?

Shark Bay in Western Australia is famous for the Peron Peninsula and surrounding islands jutting out into the Indian Ocean, the crystal-clear Shell Beach made from millions of shells, and thriving colonies of living stromatolites.

Over 300 species, including dolphins, humpback whales, and green sea turtles, inhabit the area. In particular, Shark Bay is home to the world’s largest population of dugongs, estimated at nearly 10,000 individuals.

Additionally, you can interact with dolphins and even witness sea turtle nesting, offering breathtaking experiences with nature. To preserve this precious ecosystem and wildlife, Shark Bay was designated as a World Heritage site in 1991.

Access to Shark Bay in Western Australia

You can reach Shark Bay from Perth either by car or by domestic flight.

If you rent a car, it's about a 780 km drive. Along the way, you’ll find must-visit attractions like the Pinnacles and Lancelin Sand Dunes. You can also see the rare stromatolites at Lake Thetis in Cervantes and at Hamelin Pool in Shark Bay.

By plane, it takes about 2 hours from Perth on a domestic flight. From Shark Bay Airport, it’s about a 20-minute drive to the town of Monkey Mia.

In the Shark Bay area, kangaroos and bilbies may unexpectedly cross the road, so there are signs warning of animal crossings. Be cautious of wildlife collisions if you're driving a rental car.

Shark Bay Highlight ①: Shell Beach

Shell Beach is just under an hour's drive from Monkey Mia. Head south on Shark Bay Road via Denham to reach Shell Beach Conservation Park, where the beach is covered entirely with tiny white shells.

It’s hard to believe it's an actual shell beach—and even more astounding is its scale: stretching around 100 km! You’ve got to see it for yourself.

Shark Bay Highlight ②: Monkey Mia

Most tourists who visit Shark Bay in Western Australia also go to Monkey Mia. It’s known for the diversity of land and sea animals, but its most famous residents are the dolphins. Wild dolphins visit the shallow waters of the bay almost every day.

Dolphin feeding is a hugely popular attraction. It occurs three times a day, allowing visitors to see 5 to 10 wild dolphins at once—a rare and memorable experience. Even outside of feeding times, dolphins sometimes chase fish into the shallows, delighting visitors.

Shark Bay Highlight ③: Stromatolites

Shark Bay in Western Australia is home to stromatolite colonies—the Earth’s oldest known life forms. These are algae that live in the secluded area of Hamelin Pool, and are believed to have existed for 3.5 billion years.

Stromatolites are scientifically significant as they were the first to generate oxygen through photosynthesis, laying the foundation for other life forms. Why do they still thrive around Shark Bay today? The reason is that the bay's high salinity and lack of natural predators create a favorable environment. While stromatolite fossils have been found in other places, live colonies can only be seen in select locations like Shark Bay and Lake Thetis, about 460 km to the south. The stromatolites in Shark Bay are still growing and are extremely valuable.

Some visitors to Shark Bay look forward to interacting with dolphins, but there are specific rules: touching dolphins is prohibited, and sunscreen use is restricted. Only a few people selected by rangers may participate in dolphin feeding, so be sure to follow local guidance. When visiting, it’s also advisable to bring fly nets and hats.
