Today, I plan to go near the Chilean border to see the scenery and then return.
This morning, it was raining near Mendoza, but it was sunny when I went up the mountain. This kind of thing happens sometimes.

Puente del Inca is a fascinating place and worth a visit.
I can't read Spanish, so I can't understand the explanations.

I went to an observation deck located just a little past the building of the immigration office in Argentina, and saw the Aconcagua mountain range.
Unfortunately, Aconcagua itself was hidden by clouds, but the view is nice.
