As it’s commonly know the Southern most city also called end of the world. The reason I went to Ushuaia was to visit Antarctica, however even with no intentions to do so it’s worth visiting. Best time to visit is during summer December-February, in winter it gets quite cold and snowy, with that being said there are also ski resorts, so it depends on the purpose of the trip. There are plenty of hiking trails around Tierra Del Fuego national park, where it’s possible to reach the ”end of the world”, place were the world’s longest route – Pan-American highway ends. And on the east side of the city there are many more hiking trails with amazing lakes. Organised vans, which can be booked next to the port in the center will take you there.
