Trailhead: Panticosa's Balneary (see main page for approach).
Close to the soccer field to look for the path that ascends in bows up to the Argualas's high Mallata (1h). We will take direction to the right towards the Col of Pondiellos leaving to the left side the way that takes Garmo Negro whose mass will be visible well. Under Argualas's circus we will take towards the west looking for col of Pondiellos (3h 30 min, 2810m). The Infiernos wait for us ahead after bordering on the valley for the right losing a bit of height up to coming to the base of a chimney (It is not possible to climb across the chimney without snow in summer). A little to the left of the chimney we see the way that we must to climb over the wall (degree II) to go out between the Infiernos Central and Eastern (5h). To reach the Western Infierno we will cross the ridge known as "la marmolera" being able to use the way of decrease for Tebarray's ibones that is more easy.
Water clothes in summer (recommended). In winter Ice axe and crampons of course.
