Exploring Arrecife Alacranes: A Jewel of the Gulf of Mexico

Nestled off the northern coast of the Yucatán Peninsula in Mexico, Arrecife Alacranes National Park and Biosphere Reserve protects the largest reef complex in the southern Gulf of Mexico.

The Colca Canyon: Peru's Natural Wonder

Chapada Diamantina: Exploring Nature's Masterpiece in the Brazilian Highlands

Chapada Diamantina, the "Diamond Plateau" of central Bahia, takes its name from an 1844 diamond rush that transformed a scattering of remote prospector camps into Lençóis, once Bahia's third-largest city — a mining boom whose collapse a century ago left behind the national park, waterfalls, and karst landscapes that now draw visitors in its place.
