▲As a major port city, Cartagena can get a tad busy. But it's the old walled city you want to head for. Inside is a wealth of colonial-era churches, convents, and other 16th and 17th century buildings. Make sure to pause in San Pedro Claver Plaza (pictured). UNESCO has it all covered.

▲There are more impressive ruins on the Yucatan Peninsula, but if you want to ponder the remnants of the once mighty Maya civilization without being interrupted by hoards of selfie-stick-waving tourists, then head for the remote Becan archaeological site, located in the center of the peninsula.

▲The trick in visiting Tikal National Park and the ruined ancient city of Tikal is to arrive super early, and never during summer and winter solstice celebrations (unless you want to be buried in a throng of international tourists).

▲Resembling toothpicks piercing an emerald carpet, the wax palms decorating the floor of the Cocora Valley in the Los Nevados National Natural Park stand as the national tree and symbol of Colombia.

Around 2,500 plant species (including the most orchid species found in a single place), 100 species of mammals, 400 bird species, 120 reptilian and amphibian species, and thousands of insects call this humid, verdant environment home. A network of trails run through the reserve, as well as suspension bridges and zip-lines.
