From Buenos Aires, I travelled over to Mendoza on the Western side of Argentina. Mendoza is known for it's vineyards and wine making and due to the mountainous terrain surrounding it, is also a good base for outdoor excursions.
While I was there, I signed up for a hiking trip in the hills near Mendoza. It was a nice day and we got some great views of the Andes. I also found a lot of the plants interesting, New Zealand used to be joined to Chile when it was all part of one big landmass, Gondwanaland, and so many of the species look somewhat familiar.
We also did a little abseil over the side of the waterfall which was pretty fun, especially for the people in the group who had never abseiled before, and who did a great job of it.
