Sudan, located in northeastern Africa, is a country of diverse landscapes, from the vast Sahara Desert in the north to the fertile Nile Valley in the center. The Nile River, one of the world’s longest, runs through the country, shaping both its agriculture and history.

Bratislava, Slovakia’s capital, sits along the Danube River at the crossroads of Central Europe. It's the only capital in the world bordering Austria and Hungary, which makes it an easy stop on many European itineraries. Yet Bratislava is more than a waypoint; it offers a compact city center filled with centuries of history. The Old Town’s cobbled lanes lead past Gothic cathedrals, Baroque palaces, and buildings once used by Habsburg royalty.

Agrigento, located on the southern coast of Sicily, is a city steeped in history and renowned for its ancient Greek ruins. The crown jewel of Agrigento is the Valley of the Temples, a UNESCO World Heritage Site and one of the most spectacular archaeological sites in the Mediterranean. Visitors can marvel at the remarkably preserved Temple of Concordia, which dates back to the 5th century BC and is considered one of the best-preserved Greek temples in the world.

The Whitsunday Islands sit in the heart of Australia’s Great Barrier Reef, where more than 70 islands rise from wide blue seas and offer an invitation to explore. Whitsunday Island itself is the largest of this group, known internationally for its ribbon of white silica sand stretching over seven kilometers at Whitehaven Beach. This sand feels cool underfoot even in warm sunshine because it’s made of nearly pure silica carried there by ancient ocean currents.

Erfoud, a desert town in eastern Morocco, is often seen as the last stop before the endless dunes of the Sahara begin. But this oasis holds more than just a convenient location. Known as the "Gateway to the Desert," Erfoud is steeped in history that predates the modern borders of Morocco. It was once a French colonial outpost, and today, its dusty streets and adobe buildings offer a glimpse into a slower, older way of life that still shapes the region’s identity.
