An ultralight, as the name suggests, is a lightweight, two-seater fixed-wing aircraft. It’s also not enclosed which makes it perfect for a true bird’s eye view of the Costa Rican landscape. The aerial tour takes you over the Flamingo, Conchal, Potrero, Playa grande, jungle, and beaches. There’s even a chance to see crocodiles, birds, and other wild animals. The aircraft is flown by an experienced pilot, but it’s still not for the faint of heart.

Bolivia’s Salar de Uyuni is the world’s largest salt flat. In case you were wondering, a salt flat is a thick bed of salt left behind after the prehistoric lakes evaporated. Occasionally, water from nearby lakes spills over leaving a glistening layer on top. The result is a stunning reflection of the sky. But the journey to this slice of heaven isn’t easy. The flat covers 4,086 square miles and is 11,995 feet off the ground.

Perched high atop Baños is the ‘Swing at the End of the World.’ But this is no ordinary swing. It’s affixed to a treehouse overlooking a canyon. And if that’s not enough to get your heart pumping, nearby is Mt. Tungurahua which is an active volcano.
