Medellin is known as the City of Eternal Spring because the weather stays pleasant and green all year. It is famous for its friendly people and clever modern transport.
You can glide over the hills in giant cable cars, splash through Explora Park's science exhibits, and enjoy the beautiful flowers during the yearly Flower Festival.
Medellin sits in a green valley surrounded by hills, and cable cars carry you up for breezy views. Nearby you can visit the giant rock of Guatape and climb its many steps.
Medellin has Colombia's only metro train, plus cable cars and outdoor escalators that help people zoom up steep hillsides. Riding them is an adventure by itself.
