Access via Montréjeau: head south towards Saint-Bertrand-de-Comminges, leave Saint-Bertrand on your right and continue on the D925, then the D125 to the village of Sacoué. Park opposite the church (please note: do not park in front of the drinking troughs), or alternatively in front of the cemetery (on the right as you enter the village), or in the Chemin Vidalet car park (first road on the right after the cemetery).
(S/E) With your back to the church, head straight on along Chemin du Sarrat to the next junction.
(1) Continue along Chemin du Sarrat, to the left, until you reach the end of the tarmac road.
(2) Take the path on the right which leads into the forest and continue until you come to a forest track.
(3) Turn left and walk for about fifty metres until you come to a path on the right. Turn right and follow it to a landmark rock, situated at a junction.
(4) Carry on straight ahead. Ignore the track branching off to the left.
(5) Turn right and walk for about 400 metres, climbing towards the summit. Just before the 1318-metre mark, the track widens (car park) and forms a three-way junction. Make sure you reach this junction.
(6) Turn left onto the track that climbs through the forest. This track is marked by a gate. Continue straight on to the ridge (towards Pic de Pène Toue). Please note: a few metres before reaching the three-way junction, a path branches off to the left. Do not take this path. It is easy to spot as two large stones block the entrance; it is flat at first, then descends quite steeply.
(7) Carry on straight ahead towards the ridge.
(8) Ignore the path branching off to the right and carry on straight ahead to join the ridge at Pic de Pène Toue.
(9) Turn right and follow the ridge to the summit.
(10) Enjoy the panoramic views. Return via the same route to the church at Sacoué (S/E).
