When you reach the ski slopes, continue along the road that climbs up to Charmant Som, pass the restaurant and park on the left.
(S/E) The path is signposted and goes straight ahead on a sort of road, to the left of a wooden sculpture. It is not difficult, just follow the double yellow + red and white markings.
(1) At the end of this forest road, take the path on the left and follow it to the next intersection.
(2) Keep to the right and continue straight ahead, following the markings. It's uphill! Once you reach the top of this climb, it's flat, so keep going! You will come to a T-junction.
(3) Turn left to tackle the final climb to the summit. This climb is not rock climbing, but you will need to use your hands in places to help you. Be careful in wet weather, as the rocks can be slippery. If you have them, put your walking sticks away, as they will be more of a hindrance than anything else. Reach the summit of La Pinéa.
(4) Enjoy the view. To return, follow the ascent route in reverse to get back to the car park (S/E).
