Routa 41 is a beautiful gravel road through the Patagonia National Park on the Argentine side. However, we recommend not driving them until the end of November. We drove it in mid-November 2023 and had a lot of old snow and new snow, which made driving almost impossible. We found out from a local that the road is actually passable from mid-October, but that this year (2023) it is a very cold and unusual spring with a lot of snow.
