The Melbourne Aquarium contains multiple marine animal species native to the Southern Ocean and the Antarctic. One of its highlights is a 360-degree fish-bowl viewing area. If you dare, try diving with the sharks! You will also find the largest collection of seahorses and sea dragon species in the world.

Nowhere else in Düsseldorf can one feel the city’s heartbeat so clearly as in the Altstadt. Those who want to party, people in search of culture or history lovers will all be equally well catered for in this area between the Rhine and Heinrich-Heine Allee, that covers an area of less than half a square kilometre. This tiny space is crammed with around 260 eateries, pubs, bars, discos and restaurants, and one would be hard pressed to find the like in any other city. The Altstadt is also home to Altbier – a real Düsseldorf speciality.

This impressive UNESCO world heritage medieval fortress is unique in Europe for its beauty and size and walking along its 3 kilometres of ramparts is a must. There is no entrance fee, unless you would like to take a tour on the small train which means a small fee. The site was added to the UNESCO list of World Heritage Sites in 1997.

The Edge of the World, known locally as Jebel Fihrayn, is a dramatic 1,131-metre-high escarpment marking the end of the Tuwaig Mountain range approximately 100 kilometres northwest of Riyadh. The name derives from the breathtaking panorama from the cliff's edge, where the vast, flat desert stretches to the horizon. Reaching the site requires a 4x4 vehicle and careful preparation, as the final stretch involves rugged, unmarked desert tracks with no services or reliable mobile signal. The challenging access is rewarded with stark, magnificent views, fossil-strewn terrain, and exceptional stargazing, best experienced at sunset when the cliffs glow in the warm evening light.
