Hierve el Agua, Oaxaca, Mexico

The Hierve el Agua pools in Oaxaca, Mexico, are not only a popular travel site, but also a geological, natural wonder. In Spanish, “hierve” means “to boil.” So, if you travel to Mexico, you’ll probably be expecting to see a beautiful, boiling swimming hole. But the Hierve el Agua actually appears frozen as its green, blue, yellow-tinted waters cascade down the mountain side. While the waterfalls are white, two mineral pools sit at the edge of the cliff, giving you an extraordinary view of the raw landscape straight ahead.

Laguna el Dudu, Cabrera, Dominican Republic

The blue lagoon in the Dominican Republic is an exciting and mostly unknown attraction on the north coast of the region.
