Fabulous sunset last night but we were so late getting in to our hotel, El Piñon, and getting settled in that we didn't get any shots. Feeling the altitude. Yesterday in Cafayete we were at about 1700 metres. Getting to the Puna yesterday we climbed and when we crossed the mountain pass that took us to Catamarca province in the Puna region we were, and are, at 3500 metres. When concentrating on other things altitude not particularly noticeable, but I woke up a couple of times last night very aware of being short of breath and of the need to breathe more deeply. V and I both have prescriptions for a drug that is supposed to minimize altitude symptoms which we were to have started taking two days before altitude....

Adolfo arrived at 8:30 and we set off. Long drive ahead of us and we will climb up the mountain pass into the Puna late in the day. Paved roads and good driving up the Calchaquíes valley. Smaller fields under agriculture, clearly family run, rather than the large industrial plantings that we have seen the last two days, both tobacco and vineyards. As well lots of mixed grazing, sheep, goats an some cattle....

Not sure what to expect in the next 5 0r 6 days. Have done some research and digging around but except in the most general sense, haven't yet got a good feel for the conditions, the landscape in the region that we are driving through or how and where we will be spending our days and nights. All will be revealed today by Adolfo, our driver, and we are both very excited at what we will be seeing and where we are going....

Picked up from the Sheraton and delivered to the Iguazu airport for our flight to Salta. Two hour flight north and west and arrived at about 2:00; met in Salta by Adolfo who will be our driver and guide for the next 6 days as we work our way across the Puna.

Had heard lots of good things about Salta; old and well-preserved colonial city; clean and filled with interesting architecture; and the best empanadas in Argentina...

Up with the sun, packed, breakfasted and ready for the road by 9. We were picked up by the driver who had brought us from the airport at Posadas a couple of days ago as well as a guide, Alejandro, a former teacher and park ranger at the Iguazu National Park, who had become a free-lance guide and photographer; very knowledgeable and articulate....

Today is our last day of relaxation before we drive to Iguazu Falls and then on from there to Salta where we pick up our car and driver and head out for 5 days in the Andean high plains.

Day opened cloudy and overcast but quickly cleared with a bright sun and a strong wind whirling though the trees. Our hosts made a number of suggestions for activities for us but we opted to lie in the shade and relax since we knew that we had a number of high intensity days ahead of us. Got the blog caught up, downloaded the pictures on various cameras and just slowly puttered the day away. The rest of the guests were all out on various activities and so we had the place to ourselves....

We were due to take a boat across the river to a deep, narrow bay on the Argentine side of the river near Paraguay, which is a quiet backwater about 25 metres wide, and whose banks are lined with trees full of assorted birds and monkeys. The wind had really picked up overnight and was blowing with enough force to turn the river into a welter of large breaking waves; it was not practical to take the boat across 10 or 15k of open water in the teeth of the wind and with large breaking waves so our trip was postponed until the afternoon, weather permitting....

Alarm set for 5:30 to be up for an 8:00 am flight from the BA domestic airport to Posadas which is the city and airport closest to the marshes and wetlands in Iberà where we're going to spend the next three nights.Hugh arrived with his driver at 6:30 to pick us up and drive us to the airport and just as he did the skies opened up with torrential rains so we raced to the car through an overflowing stream that had already overrun the gutter. Given the weather, happy to be leaving....
