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.

This quaint town on the Rhine is the gateway to the Black Forest and lies halfway between Freiburg and Colmar. As you walk the cobblestone streets, stop to sample local schnapps made from fermented pears or cherries and the distinctive smoky ham of this region. St. Stephan's Cathedral perches on a hillside and is the exquisite centerpiece of the town.

Montecatini Terme, in Tuscany’s Valdinievole region, is one of Italy’s most renowned spa towns, celebrated for its thermal waters and elegant Belle Époque charm.

The largest Pacific seaport in Guatemala, Puerto Quetzal is also the gateway to Antigua, a well-preserved colonial city.

The Lemaire Channel is a spectacular sight with enormous sheer cliffs falling straight into the sea. It's a narrow channel flanked by the Antarctic Peninsula on one side and Booth Island on the other.
