To see this spectacle of nature you best book a guided tour with a local provider. Nicknamed the "Horries" and known as Garaanngaddim to the local Indigenous people, are an unusual natural phenomenon where tidal flows cause waterfalls on the ebb and flow of each tide.

Christmas Island is one of the world's truly spectacular tropical seabird rookeries. It's not just the number and variety of seabirds or their magnificent splendour that make the island so remarkable, but also their sheer visibility. Around 80,000 seabirds nest here annually, with 23 breeding or resident species. Birds can be seen and heard everywhere on the island, at just about any time of the day. With just a little effort, birdwatchers can easily tick off a full list of residents in a busy week or a more relaxed fortnight. However, the elusive Christmas Island hawk owl keeps many coming back. More than 100 vagrant and migratory bird species have been recorded here, including eight breeding seabird species and one subspecies. The most numerous is the wide-ranging red-footed booby, which nests in colonies in trees in many parts of the coastal shore terraces. You may see the endangered Christmas Island frigatebird soaring above Settlement — it's the world's rarest frigatebird and nests only on the island. The golden form of the white-tailed tropic bird is an endemic subspecies unique to Christmas Island. Known locally as the golden bosun bird, this stunning bird is graceful in flight and has been adopted as the island's fauna emblem.

Head north of the city and relax at Stockton Beach. You will find that this long, wide beach with massive dunes is somewhat of a playground. Try thrilling quad-bike tours, slide down the dunes on sand boards or explore the beach on horseback.

The Djerba Traditional Heritage Museum features beautiful collections of traditional costumes as well as Jewish and Muslim jewels. The museum is located in an old Koranic education centre from the 18th century.
