estany gran de Setut

Estany Gran de Setut is a high-mountain glacial lake in the municipality of Lles de Cerdanya, in the Catalan Pyrenees (Cerdanya, Baixa Cerdanya), right next to the border with Andorra.

The lake sits at roughly 2,550–2,560 metres above sea level, on the western slope of Tossa Plana de Lles, below the Setut peaks and Tossal Bovinar. It covers about 1 hectare and reaches a depth of up to 8 metres — a small but strikingly set body of water, shaped by the same glacial forces that carved the head of this Pyrenean valley.

How do you get to Estany Gran de Setut?

Most routes start from the area around Cap de Rec, from where a trail climbs toward the Setut lakes. The long-distance GR10-11 trail also passes near this stretch of the border ridge, connecting the area with other points across Cerdanya and the frontier with Andorra. The approach is genuinely alpine: expect long sections above 2,000 metres, so good fitness, proper hiking boots, and solid route-finding skills matter here.

One popular itinerary links Tossa Plana de Lles, Estany Gran de Setut, and the Refugi del Pradell, letting hikers plan a longer mountain loop with the lake as one of the highlights along the way.

What will you see there?

Estany Gran de Setut belongs to a small cluster of lakes known as the estanys de Setut, with the nearby Estany de l'Orri also part of the group. The whole area still bears the clear marks of ancient glaciers that sculpted the headwaters of Pyrenean valleys over thousands of years: steep ridgelines, glacial cirques, and rocky crests framing the water.

The views take in Tossa Plana de Lles, one of the higher summits in this section of the Pyrenees, along with the open, rugged high-mountain scenery typical of the Catalan-Andorran border range. It's a spot for hikers looking for quiet, genuine alpine surroundings, and views well away from the more crowded trails.

When is the best time to visit?

Given the altitude — over 2,500 metres — the best window for hiking runs from June/July through September, once snow has cleared and the paths are passable. Earlier in spring and later in autumn, the approach can be difficult or hazardous due to lingering snow and ice on the higher sections.

Frequently Asked Questions

Can you swim in the lake? Given its high-altitude setting and cold water, Estany Gran de Setut isn't really a swimming spot — it's better thought of as a hiking destination and viewpoint.

How long does it take to reach the lake? It depends on the route and starting point (Cap de Rec is a common one), but given the altitude and elevation gain, it's worth planning for a full day out in the mountains.

Are there other lakes nearby? Yes. Estany Gran de Setut sits close to other lakes in the estanys de Setut group, including Estany de l'Orri, so it's easy to combine several lakes into one route.

Do you need a guide? Not strictly, but the trail crosses isolated high-mountain terrain, so hiking experience, a reliable map or GPS, and a check on weather conditions beforehand are all recommended.
