The Andes Region
The area clasified as the Andes in this website reffers to the West part of Argentina.
This includes the provinces of La Rioja, Catamarca, San Juan and Mendoza (in order, from top to bottom as you can see on the map)
The West area offeres snowy peaks and sky centers to deserts and sand dunes.
This area offers great landscapes to enjoy wether you're looking for peaceful places to enjoy the view, silence and fresh air...or adventure landscapes to do trekking and so, even if it's your first time.
This area is very dry and warm all year round, so it's good to take moisture cream (not to look pretty, but because you're skin will really ask for it). Like I said, it's a very dry area.
