Meanwhile, the Cappadocia Valley is home to thousand-year-old cave dwellings you can still visit today.

The Crescent Lake (or "Yueyaquan" in Chinese) is a fresh water spring in the shape of a half moon that sits in the Gobi Desert. The oasis is believed to have existed for around 2,000 years (though it has seen its water levels decline), and attractions include activities like dune surfing and camel riding.

At first glance, the Lencois Maranhenses Sand Dunes of northeastern Brazil look like your average set of sand dunes, but the valleys are filled with water since the low-lying lands often flood during the wet season. Fish even live in the pools.
