The approach is the same to Clarabides and I don't repeat all the route from Refuge de Estós.
See the main page.
We follow the route of Clarabide writen by my friend eza: Estós-Clarabides
because the better option is the climb of Clarabide in first time from Puerto de Gías.
On the summit of Clarabide, with an alternative visit to the small Clarabide Occidental (West), you descent the evident path to Brecha de Gías (2.953m), a very wide col under the Pico Gías. You follow the path to approach to the bottom of the peak just on left side (NE face) searching some cairn in the entry of the chimney. The chimney is an easy rock-climb (F+) but is exposed. In the first repise you cross to right (I+) to get a new repise climbing a small chimney (I+) on right side reaching a shoulder (II-) over the great fall of North face. On the shoulder you turn to left to a new repise and a very easy climb to the summit (I+).
On spring you need crampons and ice-axe to reach Puerto de Gías and even to reach the Ibon de Gías.
