in La Massana Parish, Andorra
Coma Pedrosa
Andorra's highest peak at 2,943 meters, offering challenging but rewarding summit hike with panoramic views across three countries. The ascent passes through diverse ecosystems from forest to alpine meadows to rocky summit, showcasing Andorra's dramatic mountain terrain.
Coma Pedrosa, at 2,943 metres, is the highest point in Andorra and the defining objective for experienced mountain hikers visiting the principality. The summit stands in the La Massana Parish above the ski resort village of Arinsal, accessible via a demanding trail that climbs through three distinct ecological zones: pine and silver birch woodland, open alpine meadow, and a final rocky scramble across the granite boulders and scree of the upper mountain. On clear days the summit panorama takes in the full extent of Andorra, with Pyrenean ranges in Catalonia and Ariège visible across the borders with Spain and France.
The most popular ascent begins at the Arinsal parking area, where a well-marked trail heads north into the Arinsal valley. After crossing a bridge over the Riu de les Truites, the path climbs steadily through forest before emerging onto open hillside around the Estany Negre, a dark glacial lake roughly halfway to the summit. From Estany Negre the trail steepens across a boulder field before reaching the Refugi de Coma Pedrosa, a mountain hut operated by the Andorran Mountaineering Federation that offers meals and dormitory accommodation during the summer season. The final push to the summit from the refugi involves approximately 200 metres of elevation gain across the rocky ridge, with some basic handhold scrambling on the uppermost section.
The total elevation gain from Arinsal is around 1,000 metres, and the round trip takes six to eight hours for hikers with good mountain fitness. Parties with appropriate experience sometimes extend the route along the summit ridge towards the Spanish border, returning via the Tristaina lakes and Ordino Arcalís — a demanding full-day traverse requiring navigation skills and a vehicle shuttle at the finish.
Summit conditions can deteriorate rapidly: afternoon thunderstorms are common from July through August, and the upper section holds snow until well into June. A very early start — before 7am from Arinsal — is strongly advisable. The peak sees moderate traffic on summer weekends; midweek ascents from late June through mid-July offer the best chance of a clear, uncrowded summit.

FAQ
How difficult is the hike to Coma Pedrosa?
The ascent is rated demanding, requiring good cardiovascular fitness and comfort on rocky terrain. The 1,000-metre elevation gain and six-to-eight-hour round trip place it well beyond casual hikers; prior experience on mountain trails and appropriate footwear are essential.
Can the mountain refugi be used for overnight stays?
Yes — the Refugi de Coma Pedrosa accepts reservations for dormitory accommodation during the summer season (approximately June to September). Booking in advance is strongly advisable for summer weekends, when the hut fills quickly.
Is photography allowed at the summit?
Photography is unrestricted throughout the route and at the summit. The panorama is clearest in the morning before haze builds, and the golden hour after sunrise offers exceptional visibility across the Andorran valleys below.
Accessibility
Coma Pedrosa is accessible only to fit hikers on rough mountain terrain involving 1,000 metres of elevation gain and basic scrambling near the summit. The route is not accessible by wheelchair or for visitors with limited mobility. No adapted facilities exist at the Arinsal trailhead.
When to visit
Late June through mid-September offers snow-free trail conditions and reliable summit access. July and August are warmest but carry the highest risk of afternoon thunderstorms; starting before 7am is essential. Midweek visits in late June and early July combine good conditions with lighter trail traffic.
