Cat Island, one of the more unspoiled Out Islands of The Bahamas, is a destination that feels worlds away from the busier resort hubs. Stretching about 50 miles long, the island is lined with pink-sand beaches, rolling green hills, and quiet fishing villages where time seems to stand still.

Khiva, located in western Uzbekistan’s Khorezm region, is one of Central Asia’s most evocative Silk Road cities. Its walled inner city, known as the Itchan Kala, has preserved a remarkable collection of mud-brick architecture, minarets, mosques, and madrasahs that reflect centuries of Islamic culture and trade. Khiva served as a thriving trading hub and political center, linking merchants and scholars across the desert routes of the region.

M’Hamid El Ghizlane sits deep in southeastern Morocco’s Sahara, where the paved road ends and endless sands begin. Travelers often arrive from Zagora, taking in the wide palm groves fed by ancient irrigation channels that show how people have sustained life here 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.
