Once the commercial center of the ancient world, Ephesus is an archaeological splendor and an essential stop on any visit to Turkey. The city, whose wealth and patronage support its splendid architectural program, was dedicated to the goddess Artemis.

Passau sits on the confluence of the Danube, the Inn and the Ilz, so it is fitting that it is known as "the Dreiflüssestadt", which means the “City of Three Rivers.” The historical center offers a cathedral, churches and museums to explore, and the embankment is perfect for a romantic stroll.

Quintana Roo, nestled on the Caribbean coast of Mexico’s Yucatán Peninsula, is a paradise that seamlessly blends ancient history with modern luxury. The state is perhaps best known for its glittering beaches and turquoise waters, epitomized by destinations like Cancún and Playa del Carmen.

Rabat, the capital of the kingdom of Morocco, is located on the edge of the Atlantic Ocean on the left bank of the Bou Regreg Estuary. A city of trees and flowers, Rabat combines peace, beauty and Serenity, and is steeped in history.

Hidden in the northern region of Costa Rica, the Celeste River (Río Celeste) winds through Tenorio Volcano National Park with a color so vivid it seems unreal. The river’s striking turquoise hue is caused by a natural chemical reaction between two mineral-rich streams, Quebrada Agria and Río Buena Vista, which merge at a point known as "El Teñidero." This one-of-a-kind phenomenon creates the illusion that the water has been dyed blue, even though no pigments are present.
