South America is a continent of striking contrasts, where towering mountain ranges meet vast rainforests, arid deserts, and sprawling coastlines. From the icy fjords of the south to the tropical warmth of the north, each region offers its own landscapes, wildlife, and cultural expressions.

Gotland, Sweden’s largest island, sits in the Baltic Sea and feels like a world of its own. Its main town, Visby, is a UNESCO World Heritage site and one of the best-preserved medieval towns in Northern Europe. Surrounded by a 3.5-kilometer stone wall with original towers still intact, Visby once served as a key Hanseatic trading hub. Visitors can walk along cobbled streets lined with rose-covered cottages, explore Gothic church ruins, and climb up the city wall for views over the harbor.

Londonderry, often called Derry, is a city steeped in history and charm, uniquely surrounded by remarkably well-preserved 17th-century walls. In fact, it holds the title of being the only completely walled city in all of Ireland. Strolling along these ancient ramparts offers visitors not only a glimpse into the past but also breathtaking panoramic views of the winding River Foyle and the lively streets below.

An essential passageway between the Atlantic and Pacific Oceans, the Panama Canal is an extraordinary technological landmark and a testament to human innovation. Built in the early twentieth century by American engineers, the canal weaves through the Panamanian isthmus and allows easy access for commercial freighters and cruise ships alike.

Mayotte, a French overseas department nestled in the Mozambique Channel between Madagascar and mainland Africa, offers travelers a window into a lesser-known island culture shaped by Swahili, Malagasy, and French influences. Unlike its neighbors in the Comoros archipelago, Mayotte remains part of France, giving it a unique blend of European infrastructure and Indian Ocean traditions.
