Kinshasa, the capital of the Democratic Republic of the Congo, is one of Africa’s most vibrant and unpredictable cities. Sprawling along the banks of the Congo River, it’s the third-largest city on the continent and pulses with music, art, and personality at every turn. Across the river lies Brazzaville, making Kinshasa part of the only pair of national capitals facing each other across a single waterway.

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.
