The Northwestern part of the country is, mostly, a mountaineous region with spectacular landscapes.
It stands, to the west, as an elevated plateau (of approximately 3800 m.a.s.l.), crossed by high mountain ranges. In its central part there are gorges (such as the Humauaca Gorge) of a huge slope. To the East, we find sierras that barely exceed the 2000 metres, as a transition to the chaqueña plain.
The tourist Train to the Clouds (one of the highest trains in the world), gives you the possibility of enjoying these landscapes in an unparalleled way.
In these mountains you will find the contrast of the snow in the highest peaks, and the red, violet and green colours of the living rock.
There are zones of forests with an important variety of fauna carefully preserved in the national parks.
In this whole region you can find picturesque villages lost in unparalleled natural scenaries.
The Río Hondo thermal baths are internationally known due to its healing powers.
