If you find yourself in Rotterdam, there's a strong chance you've arrived by water. This popular port city (the second largest in the Netherlands) has gone through an architectural renaissance since World War II, with daring, innovative structures dotting the city (cube houses!) and defining its skyline. Café culture is on the rise here, so grab yourself a table and a cup.

Inyeug, more commonly known as Mystery Island, is a tiny, uninhabited islet off the coast of Aneityum in Vanuatu’s southernmost province. Measuring just 1.5 kilometers long, the island is completely free of roads, shops, and electricity. What it offers instead is pure seclusion and untouched beauty. Cruise ships often anchor offshore, bringing day visitors to its white-sand beaches and shallow coral lagoons, but once they depart, the island returns to stillness.

Chiang Rai, in northern Thailand near the borders with Laos and Myanmar, is a city where history, art, and tranquil landscapes converge.

Austria is located just east of Switzerland; northeast of Italy. The foremost attraction is skiing or hiking the Alps--equally breathtaking whether you're among its glorious peaks or at ground level.

Polonnaruwa, located in Sri Lanka’s North Central Province, served as the island’s capital nearly a thousand years ago.

Visitors can walk among the ruins of royal palaces, Buddhist monasteries, and intricately carved stone temples. One of the highlights of Polonnaruwa is the Gal Vihara, a group of colossal Buddha statues carved directly into granite.
