At the southernmost tip of South America, beyond the Andes, lies the beautiful and colorful city of Ushuaia, regarded by some as the southernmost city of the world. And just beyond the city’s outskirts run a small steam railway originally built to serve the penal colony of Ushuaia. Today, the Southern Fuegian Railway takes tourists along the picturesque Pico Valley, through the thickly-forested Toro gorge and into the stunning national park.
