From Arinsal to a hiking hut and an idyllic lake in the Coma Pedrosa valley at the feet of Andorra's highest massif. The gorge-like, lower part of the valley forms the centerpiece of the tour, which is characterized by many beautiful places and a varied landscape experience.
Approximate walking time way there and back: 4 h 15 min without rests.
First, the tour goes uphill for a short distance in the Arinsal valley to the Aigues Tortes where the valley ramifies into the high valley Pla de l'Estany in the north and Coma Pedrosa in the west. It takes a gravel road that goes quite evenly uphill near the Pollos River and slightly above the wooded valley floor. Passing by a water reservoir, it continues uphill, with beautiful views of the Pic de Alta Comosa, and reaches a bifurcation after crossing a cattle grid (Barrer d'Areny). There it leaves the gravel road and continues as a trail that approaches the valley bottom. Near the Aigues Juntes, the confluence of the river coming from the high valley of Pla de l'Estany and the Riu de Coma Pedrosa, both watercourses are crossed on footbridges, after which the tour is on the right side of the lower Coma Pedrosa valley.
This is followed by a very strong ascent on partly rocky, rough ground along a steep mountainside at the bottom of the valley. After overcoming the steep stretch of path, the slope becomes somewhat lower. The narrow valley, deeply cut into the mountainsides, is characterized by thick bush and shrub vegetation and the river, which makes its way down in a larger waterfall and some smaller rapids. The path stays close to the river for a short while and allows beautiful views of the waterfall. It then leaves the watercourse and reaches a very small cirque, from where it ascends a short, slightly steeper stretch up to the pass Collet de Coma Pedrosa, the gate to the upper Coma Pedrosa valley. There a wide valley basin opens up, with a depression and alpine meadows in the foreground, the Coma Pedrosa massif on the right and a circle of summits to the west and south.
The hike continues with a short ascent to an elevation to the left of the pass with the Refugi de Coma Pedrosa. The hiker's hut, conveniently situated at the eastern edge of the upper valley, is an extraordinary viewpoint with wonderful views across the uplands to the summits framing the valley and the mountain chains to the east on the other side of the Arinsal valley. From the hut it is only a few minutes to the Estany de les Truites, the "trout lake", which is beautifully situated at the feet of the Pic dels Aspres.
The hike has no technical difficulties or dangerous spots. A certain level of surefootedness and prudence is required especially in wet weather.
For hikes in early spring, there is a comparatively low avalanche risk nevertheless needing to be considered.
Refugi de Coma Pedrosa is managed from the second week of June to the first week of October inclusive.
Depending on the prevailing general weather situation and the trail conditions to be expected, the hike can also be undertaken outside the recommended months, but not during winter. In the early autumn, from the end of September / beginning of October, first snowfalls can occur in the higher altitudes.
