One of the largest Ocean Discovery Parks in Europe, the Océanopolis has four pavilions — polar, temperate, tropical and biodiversity — that tell the story of the sea and marine life in different world climates. The park contains an impressive 7 shark species.

A world heritage listed marine park, the Great Barrier Reef extends for 2,300 km along the North Eastern coast of Australia. It’s the world’s largest coral reef system, comprising a network of about 2,900 individual reefs and home to nearly 2,000 species of fish. Whether taking a scenic flight, cruising, diving, snorkelling or admiring this wonder through an underwater viewing chamber, seeing it is one of the most magical experiences on the planet. One of the ways to explore the Reef is to get a package tour from Cruise Whitsundays: Day tours of the Great Barrier Reef organised by Cruise Whitsundays depart from Hamilton Island Marina every day at 9am.

The Bells Monument outside the city centre of Sofia was installed in 1979, when UNESCO declared it International Year of the Child. The monument presents more than 70 bells from across the world, on pillars that are marked with a message from children from the respective nation. Occasionally, the seven main bells, one for each continent at the top of the central pillar, ring along to parades or events held around the monument.
