Alto del Griu Trail is open year-round, although visiting between June and October is recommended for better weather and no snow.

More details are available on the official Visit Andorra website.
Visiting Alto del Griu Trail is completely free, as it is a natural trail in Sorteny Natural Park with no entrance fees. You will only pay for transport if you use the bus or parking in Grau Roig, which costs around €5–10. Check for updates on Visit Andorra.
It is recommended to allow between 2 and 3 hours to complete the trail round trip, depending on your pace and whether you stop for photos or to enjoy the views. It is a moderate route of about 4 km with elevation gain, ideal for a morning walk. Bring water and snacks to keep your energy up.
Alto del Griu Trail is part of the old shepherds' and smugglers' routes in the Andorran Pyrenees, with cultural importance as a historic passage toward Spain through Port de Cabús. It offers impressive views of Casamanya Peak and connects with Andorra’s natural heritage, highlighting the area’s biodiversity. For more about its history, visit Visit Andorra.
The best time is in summer, from July to September, when the weather is warm and the wildflowers are at their best; avoid winter because of snow. Early morning is ideal to avoid the heat and enjoy better visibility for the panoramic views. Check the forecast on local apps before you go.
Alto del Griu Trail is not accessible for people with reduced mobility, as it involves uneven terrain with stones and an elevation gain of about 200 meters, with no ramps or paved paths. If you need adapted options, consider flatter routes in Encamp. Contact Visit Andorra at +376 750 100 for alternatives.
Nearby you will find the Grandvalira ski resort in Grau Roig, perfect for winter activities, and the town of Encamp with its Romanesque church and the Funicamp gondola. You can also explore Juclar Lake, just 1 extra hour of hiking away. All of this is in the parish of Encamp; plan your route at Visit Andorra.
Bring sturdy hiking shoes, sunscreen, and at least 1 liter of water per person, as there are no fountains along the route. Download a GPS map from Andorra’s official app or use the on-site signage; go with company if you are a beginner. If it rains, postpone your visit because of the slippery ground, and book transport in advance during high season.
