A true gem on the Caribbean coast, the port city of Cartagena (Cartagena de Indias) welcomes visitors with its charming old town, colonial buildings, and exceptional beaches. A popular cruise ship stop, many seafarers find themselves honorary Cartagenans, as they stroll shady, cobblestone lanes and gaze upon impressive churches.

Copper River, Alaska's fourth largest river travels from the dry interior climate to the temperate rainforest along Prince William Sound.

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.

Sintra, located just 40 minutes from Lisbon, feels like a world apart. Tucked into the hills of the Serra de Sintra, this town has drawn kings, poets, and explorers for centuries. It was once the summer retreat of Portuguese royalty, who left behind palaces and gardens that seem pulled from a storybook. The most famous, Palácio da Pena, is perched high above the town with bold red and yellow towers that blend Romanticism with Moorish and Gothic styles.

North Conway, located in New Hampshire’s Mount Washington Valley, has drawn visitors since the mid-19th century, when artists from the White Mountain School began painting its dramatic landscapes. Today, the area still offers scenic appeal, anchored by the towering presence of Mount Washington, the tallest peak in the northeastern U.S. Historic photographs and lithographs of North Conway hang in galleries downtown, showing just how little the iconic views have changed in over 150 years.
