Ciudad Perdida: This Colombian site known as "The Lost City" was founded around 800 CE, some 650 years earlier than Machu Picchu.

Nearby: The closest city to Ciudad Perdida is Santa Marta, and the closest major airport Barranquilla.

Getting there: Currently, the only way to visit Ciudad Perdida is via a not-for-beginners multiday hike.

In the thick of it: Deep in the Colombian jungle, the entrance can only be accessed by a climb up (and then back down) some 1,200 stone steps.

Going deep: Ciudad Perdida consists of a series of 169 terraces carved into the mountainside, a net of tiled roads and several small circular plazas.

On the way: There's only one trail to the site, meaning visitors must go back the same way they arrived.

Lost and found: Historians believe that the city was abandoned around the time of the Spanish arrival and conquest. It was rediscovered in the 1970s.
