Jebel Akhdar, meaning “Green Mountain,” is a highland area within Oman's Al Hajar Mountains in Ad Dakhiliyah Governorate. The mountain rises to about 2,980 meters, with the Saiq Plateau located around 2,000 meters above sea level. Its cooler mountain climate supports terraced orchards, villages, and vegetation that differs from the dry lowlands below.

Etosha National Park, located in northern Namibia, is one of Africa’s most renowned wildlife destinations.

McMurdo is distinctive not only for its scientific role but also for the unusual scale of daily life in Antarctica. The station has a power plant, medical facilities, dining services, workshops, communications systems, and specialized vehicles used to support research in extreme conditions. Nearby Scott Base, operated by New Zealand, provides another important Antarctic research presence on Ross Island. McMurdo also supports flights and overland journeys to remote parts of the continent.

Scoresby Sund (Kangertittivaq in Greenlandic), on the eastern coast of Greenland, is the largest and longest fjord system in the world.

The region is well-known for its Arctic flora and fauna.

Mljet National Park sits on the western side of Mljet Island in Croatia’s Adriatic Sea, a place where saltwater lakes meet ancient forest pathways. The park stretches across nearly one-third of the island, with Veliko Jezero (Great Lake) and Malo Jezero (Small Lake) as their most striking features. These two saltwater lakes are connected by a narrow channel to the open sea, creating calm blue waters that draw visitors for swims, casual kayak outings, or peaceful cycles around the shaded paths.
