Hiking trail in Incles Valley, Canillo, Andorra
Estany de Juclar
A popular route to Andorra's largest natural lake at 2,310m elevation through the Incles Valley. Crystal-clear glacial waters surrounded by dramatic peaks make this one of the most rewarding hikes in the principality.
The Estany de Juclar trail follows the Incles Valley in the parish of Canillo, leading hikers to Andorra's largest natural glacial lake at 2,310 metres elevation. The trailhead is located at the end of the Incles Valley road, accessed by driving from Canillo village along the CG-2 and then the CS-240 into the valley. A small car park sits at the road's end near the Bordes de l'Ensegur farmsteads. No hiking permit is required.
The route covers 10 kilometres round trip with approximately 680 metres of elevation gain over four to five hours. The first half of the trail follows a well-defined dirt track alongside the Riu dels Pessons through the broad Incles Valley floor, passing traditional stone bordes — summer farmsteads used for centuries of Pyrenean pastoralism. The valley terrain is gentle and scenic. After crossing a wooden footbridge, the path steepens considerably, climbing through boulder-strewn grassland and over exposed rocky sections before reaching the lake basin.
Estany de Juclar occupies a dramatic glacially carved cirque ringed by peaks rising above 2,600 metres. The lake's waters are crystal clear and cold, fed by snowmelt and small tributaries from the surrounding ridgelines. Wild swimming is widely practised in July and August, though water temperatures rarely exceed 14°C even at the height of summer. A rough stone shelter near the lake's shore provides basic wind protection but no services. Several smaller satellite lakes are accessible within 20 to 30 minutes of scrambling around the lake basin for those wishing to extend the excursion.
Wildflowers including Pyrenean iris, saxifrage, and yellow mountain poppy line the upper approaches in June and July. The trail surface varies from compacted gravel on the valley floor to loose rock and grassy tussock on the upper climb. Minimal shade exists above the treeline, making sun protection essential. The trail is well-marked with painted waymarks throughout.

Tips
- Arrive at the Incles Valley car park before 9am on summer weekends to secure a space — the road fills completely by mid-morning.
- The upper approach can be slippery on wet rock — poles and grip footwear are advisable even on fair-weather days.
- A side scramble south-east of the main lake reaches two smaller satellite lakes that see far fewer visitors.
- Weather deteriorates quickly above 2,200m — turn back if cloud builds rapidly over the surrounding ridgeline.
- Lake water is drinkable when filtered; a lightweight filter reduces pack weight on the ascent.

When to visit
Late June to mid-September provides the best conditions, with snow largely cleared from the upper basin and the valley wildflowers at their peak in July. The trail is accessible on snowshoes in winter but requires navigation experience.
