Route Description 1B.Panticosa-Col Pondiellos
Close to the soccer field in the other side of the big lake we look for the path that ascends in bows up to the Argualas's high Mallata across a evident zig-zag (1h). We take direction to the right towards the Col of Pondiellos leaving to the left side the way that go to Garmo Negro whose mass will be visible well. We take towards the west looking for col of Pondiellos following the cairns (3h 30 min, 2810m).
Route Description 2Col Pondiellos-Brecha Arnales-Ridge
In the col of Pondiellos we follow the little path between the stones to right side under the west side of Pico de Pondiellos (2917m). We arrive to other col, the Collado de Saretas, under the impressive rocky south face of Arnales. This is a possible route or rock climb (PD, grade II) but the normal route goes to the north following the path in direction to the couluoir of south face of Picos del Infierno. In the point that we don't see the ridge of Arnales in right side we turn to the east (right) to the gap between Picos del Infierno and Arnales. The ramp of access is long and has 30º with snow to reach the Brecha de Arnales with the little Aguja Sur de Infiernos (3002m) in left side and the final ridge of Arnales in right side. Be carefull with the cornises in the col with snow.
We attack the final rocky ridge of grade I+. It has a lot of free stones in some parts and we can to evitate the edge in some points to finally reach the main summit with a great cairn (Arnales, 3002m).
In the summit we can see the south summit (2995m) but it's not higher, you don't need to climb this other summit.
