In April of 2018, my wife and I decided to go all out, and booked a two week, professionally led photo tour of Patagonia. The route started in south central Chile, passed into Argentina, and ended up back in Chile at Torres del Paine National Park.
The first two days looked good, but then it turned rainy. We lost several days of shooting gorgeous mountains due to the rain and clouds that totally obscured the view. Sometimes we would find a waterfall or river as an alternative, plus a lot of guanacos, and we did get a couple of rainbows.
As if that was not enough, in the middle of the trip the main vehicle broke down. We lost another full day in a nowhere tiny town waiting for alternative transportation. Even when we were moving again, there were still the low clouds and rain.
Eventually we got to Torres del Paine, and the weather improved a little. It was still cloudy but at least you could see things. The famous mountains here are Los Cuernos, or "The Horns". After visiting a lake with small icebergs that had calved off of a glacier, we were passing by the Horns on the way back to our lodging. We made a stop to capture the mountains emerging from behind the clouds.
