Hiking trail in Arinsal, La Massana, Andorra
Coma Pedrosa Summit Trail
The ascent of Andorra's highest peak at 2,943m rewards hikers with panoramic views spanning three countries. The trail begins at Arinsal parking, climbs through forests and meadows past Refugi de Coma Pedrosa to the rocky summit.
The Coma Pedrosa Summit Trail leads to the highest point in Andorra, the 2,943-metre Pic de Coma Pedrosa, located in the municipality of La Massana near the village of Arinsal. The trailhead is accessed by driving through Arinsal village to the dedicated car park at the end of the valley road, approximately 4km above the village centre. No hiking permit is required. Parking is free, though space fills quickly on summer weekends, making an early start advisable.
The trail covers 12 kilometres round trip with a total elevation gain of approximately 1,100 metres over a duration of six to eight hours. From the trailhead the path climbs steadily through mixed pine and birch forest before opening onto broad alpine meadows dotted with wild gentians and arnica. At roughly the halfway point, hikers reach the Refugi de Coma Pedrosa at 2,260 metres, a staffed mountain refuge operated by the Federació Andorrana de Muntanyisme. The refuge provides hot meals, snacks, and overnight bunks during the summer season, making it an ideal lunch or turnaround point for those not continuing to the summit.
Above the refuge, the terrain transitions to open rock and scree. The upper section involves moderate scrambling over exposed ridgeline before the final rocky push to the summit cairn. The surface is predominantly loose scree above treeline, requiring sturdy ankle-support footwear. There is no shade above the refuge and no water source on the upper section.
The summit offers 360-degree views spanning Andorra's seven parishes, the Catalan Pyrenees of Spain to the south, and the French Ariège department to the north. The glacial lake Estany de les Truites sits visibly below the summit at approximately 2,450 metres and makes a worthwhile detour. The descent follows the same route; parties with strong navigation skills sometimes vary the return via alternate ridgeline paths. Parties should be off the summit by early afternoon due to the rapid development of thunderstorms at elevation.

Tips
- Start by 7am in summer to avoid afternoon thunderstorms, which develop rapidly above 2,500m after midday.
- The Refugi de Coma Pedrosa sells food and drinks; no need to carry a full day's provisions if planning a lunch stop there.
- Crampons and an ice axe are advisable before late June, when snow can remain on the upper scree and ridgeline.
- The summit area is fully exposed with no shelter — carry wind and rain layers regardless of morning conditions.
- Poles significantly reduce knee strain on the 1,100m descent over the rocky lower section.
FAQ
Is the Coma Pedrosa trail suitable for beginners?
It is rated challenging due to the 1,100m elevation gain, rocky summit terrain, and six to eight hours of sustained effort. Hikers should be comfortable with prolonged uphill exertion and basic rocky scrambling before attempting it.
Is the Refugi de Coma Pedrosa open year-round?
The refuge operates seasonally, typically from late June through late September. Outside these dates the building is locked and no services are available. Check current operating dates with the Federació Andorrana de Muntanyisme before planning.
Can the trail be done in winter or early spring?
The upper section accumulates significant snowpack and the ridgeline becomes an exposed alpine route requiring crampons and ice-axe experience. The trail is not recommended for casual hikers outside the July to September window.
Where exactly does the trail start?
The trailhead is at the Arinsal car park at the end of Carrer de les Canals in Arinsal village, La Massana. From Andorra la Vella, follow the CG-4 north to La Massana and then the CS-140 to Arinsal — approximately 20 minutes by car.
Accessibility
Not wheelchair accessible. The trail involves 1,100m of elevation gain over rocky, uneven terrain with no paved or adapted sections above the village car park. Not suitable for mobility-impaired visitors or strollers.
When to visit
Mid-July to mid-September offers the most reliable summit conditions, with snowpack cleared from the upper section and the Refugi de Coma Pedrosa open for services. Afternoon visits should be avoided in all seasons due to rapid storm development above treeline.
