Park in the car park at Port de Larrau, on the border with Spain.
(S/E) Above the car park, take the clearly marked path heading due west. This path follows the Spanish side of the mountain without difficulty, rising gradually.
A short rocky section, equipped with a handrail, can be slippery when wet.
The Pic d'Orhy then comes into view at the first fork in the path.
(1) There are two routes to the summit:
- at the junction, take the left-hand path continuing due west to the small pass, then turn right, heading due north, to reach the summit via a less steep path.
- follow this track and take the path on the right, which climbs gently at first and then steeply towards the summit before reaching the ridge and continuing to the peak.
(2) From the summit, crowned by a small pillar, admire the view, then descend via the path heading due south to the small pass.
(3) Turn left to return to the first junction.
(1) Return to the Port de Larrau (S/E) via the reverse route of the outward journey.
