0,00 h. Parking of the Besurta. 307689 - 4727755 - 1907. There is a bar, open to certain hours. We followed the indications the refuge of the Renclusa.

0,40 h. Refuge of the Renclusa. 307563 - 4726962 - 2139. We happened before the refuge and we continued raising by the valley that has the tops between the Maladeta and the tip of alba like bottom drop curtain. In no case we must cross the stream of the Renclusa. The way, if there is no snow, passes by tartera, in strong ascent. We followed until we surpassed a strong slope, level 2,860 ms. Here we left the valley and we turned (E) to the left, more or less of level, to obtain the crest of the Portillones.

3,10 h. Portillón Superior. 307201 - 4725329 - 2897. It is important to find this step, that it lays the way to us of the glacier. If one goes away above it can have complications. From the Portillón already we see the top of the Aneto, at the end of the immense glacier. They must lower about 20 ms, by a narrow and quite pending channel, that demands prudence, mainly if is snow. We crossed the glacier, first in direction S, later SE, without lowering never, always by the high part, that is the one that reunites better conditions.

4,30 h. Collado de Coronas. 307678 - 4723158 - 3173. Important step, on the same foot of last steep slope. Often the snow is frozen.

and 5,10 h. Aneto. 307947 - 4722713 - 3404. Before arriving at the top properly this we must surpass the famous Passage of Mahoma, short very aerial crest that causes that many make the decision to save it to it. The vision that is has is majestic, over any mountain and tip that can be seen, that, if the day is good, they are infinity.

The return is made generally by the same way. They are around four hours.
