Soaring Andean summits, unspoiled Caribbean coast, enigmatic Amazon jungle, cryptic archaeological ruins and cobbled colonial communities. Colombia boasts all of South America's allure, and more. Colombia's equatorial position affords it a diversity of landscapes matched by few countries. A slight tinkering in altitude takes you from sun-toasted Caribbean sands to coffee-strewn, emerald-green hilltops in the Zona Cafetera. Continue to climb and there's Bogotá, the bustling cradle of Colombia and third-highest capital city in the world. Throw in another few thousand meters and you'll find snowcapped peaks, high-altitude lakes and the eerie, unique vegetation of the páramo (high-mountain plains). The bottom drops out as the Andes give way to Los Llanos, a 550,000-sq-km swath of tropical grasslands shared with Venezuela, often called the Serengeti of South America.
