ABERDEEN -- Scotland's third-largest city (pop. 187,000) is characterized by buildings of beautiful white granite. Set beside the North Sea, Aberdeen is both a university town and the capital of the Scottish oil boom. It is also one of Scotland's largest seaside resorts (though its appeal is confined to those who like their water well-chilled).

Bacalar sits on the tranquil shores of Laguna de Bacalar in southern Quintana Roo, Mexico, and has been a meeting place for people and cultures for centuries.

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.

Belém do Pará sits at the edge of the Amazon, where river and bay meet in a landscape with activity and color. The Ver-o-Peso Market spreads along Guajará Bay, welcoming early morning boats laden with fresh fish, herbs, fruits, and Amazonian goods. Recognized by UNESCO as a Creative City of Gastronomy, the local cuisine marries Indigenous, Portuguese, and African traditions to create dishes found nowhere else.
