We flew from the UK to Buenos Aires but the next day flew to Puerto Iguacu as we were attending a conference in Foz do Iguassu, Brazil. The local agency arranged for a driver to collect us and take us through the border to our hotel on the Brazilian side. At the end of the confetence the same arrangements were made for our retun to Buenos Aires. We then left the next morning to fly to Bariloche, an alpine town in a lovely setting. We had a very comfortable hotel with a nice room overlooking the lake. While there we had two trips, one to the Seven Lakes and the other to the Black Glacier. After Bariloche we went on to El Calafate. This was a shortened visit due to the strike mentioned above. However our two days there at the Perito Moreno Glacier and El Chalten were fantastic days. From there we flew to Ushuaia and went on two trips, both to National Parks, the second including the End of the World train. It was interesting being in the city which is the most southern city in the world. We then returned to Buenos Aires for two nights. The hotel was in a very good neighbourhood, Recoletta, which felt safe for going out. We had a city tour in the afternoon which I would recommend as it enables you to see parts of the Ciity which would be difficult to do independently in a short space of time.
