Coming back from Antarctica my ship stopped in the most southern city on the planet Ushuaia.
It is close to Tierra del Fuego National Park so it is a popular stop if you are in the area.You can take a local bus or a taxi.I would advise you simply take a Tour and save the hassle.A bus would cost about 21 USD and the entrance to the Park about 15USD
Here it is often windy and cold and you can often sprinkle some rain as well.
The area is one of the highest concentrations of Cataracts in the World because of the depletion of the Ozone Layer.It has improved recently but suggest you use a good Suntan lotion and of course Sunglasses as well.
As usual Photos are a great way to get a feel for the area.
