Elephant Island, a remote outcrop off the coast of Antarctica, is not your average travel destination. Known for its dramatic cliffs, towering glaciers, and wild, ice-laced seas, this island is both stark and unforgettable. Located 245 kilometers northeast of the Antarctic Peninsula, Elephant Island is rarely visited except by specialized expedition cruises.

Gozo, the smaller sister island of Malta, offers a tranquil contrast to the busier main island, blending rich history, rugged landscapes, and a slower pace of life. Known for its rolling hills, picturesque villages, and dramatic coastline, Gozo has preserved much of its rural charm, allowing visitors to step back into centuries of Mediterranean culture and tradition.

Tunis' white-washed, blue-shuttered buildings hide a treasure trove of Arabic and Ottoman art. Inspect illuminated manuscripts from the Koran, follow the twists and turns of the fascinating old Medina (inner city), marvel at the ornate Palace of Dar Ben Abduallah and the magnificent Djamaa-Ez-Zitouna Mosque, whose 184 columns were "recycled" from the rocky ruins of Carthage.

Trebinje, the southernmost city in Bosnia and Herzegovina, sits just a short drive from the Adriatic coast but offers a completely different rhythm. Framed by hills and set along the Trebišnjica River, the city has a history stretching back to Roman times. The river that winds through the city is one of the longest sinking rivers in the world and often disappears underground and resurfaces in various places.

Together with neighboring Glacier National Park in the United States, Waterton Lakes National Park is part of the world's first international Peace Park, which was recognized as a UNESCO World Heritage Site in 1955. The Waterton-Glacier Peace Park protects an important biological crossroads where the Rocky Mountains reach their narrowest width. Waterton's bedrock is much older than that of the mountains to the north found in Jasper and Banff.
