Met up with an English chap and an Aussie couple to walk up to the French valley. Bit cloudy to start with and we met a couple coming down so said that you couldn't see anything up there. We pressed on regardlessly and are efforts were duly rewarded when the sun burnt off the clouds, leaving not a cloud in the sky. The French valley was stunning; huge towers of rock everywhere you looked.
It was a long trek back to Los Cuernos, a nice 10 hour day, but worth it.
