Four hours of light

There is a morning in the Chaltén valley when the granite goes the colour of a struck match. It happens perhaps forty minutes before the sun is properly up, it lasts about four minutes, and every photograph you have ever seen of Fitz Roy was taken inside that window.

The window is not the difficult part. The difficult part is that it needs a clear eastern horizon, and Patagonia gives you one morning in four.

So we build the week around it. Not the day — the week. Three days sit in every itinerary doing nothing at all: no drive, no lodge change, no booked table. They exist so that when the forecast turns at nine at night, the guide can knock on four doors and move the whole group without asking anyone to give something up.

Guests almost never notice those days as days. They notice them as the morning it worked.

This is also why we cap the group at eight. Ten people leaving a lodge in the dark is a thirty-minute operation. Eight is twelve minutes, and twelve minutes is the difference between standing at the lagoon in the light and walking towards it while the light goes.

If you take one thing from this note: when you compare two Patagonia weeks and one is cheaper, count the fixed nights. The cheaper week is usually the one that has sold you every day in advance.
