The Tristaina lakes, three tarns under the peak

Ask me for just one walk in Ordino and I’ll say Tristaina. Three lakes stepped up a glacial cirque, a short path anyone can start, and a finish that I’d put among the most complete views in Andorra. Spain’s Foreign Ministry lists them among the country’s most important lakes, and I’m not surprised.

Three lakes in a glacial cirque

The Tristaina lakes sit at the head of the Ordino valley, inside the Ordino Arcalís ski area, above 2,300 m. The tourist board describes them one by one. First comes Primer, the smallest but with the bluest water; then del Mig, ringed by scree and cols; and last Més Amunt, the largest, round and set in classic glacial terrain at the foot of Tristaina peak, 2,878 m.

Along the way the same listing mentions alpine flowers, Percheron horses grazing free and stoats. At the start of the walk stands Arcalís 91, a four-metre steel ring by the sculptor Mauro Staccioli, which is the photo nearly everyone takes before setting off.

How do you get to the Tristaina lakes?

Drive up the CG-3 to Ordino Arcalís. In winter the area is part of the ski resort; in summer, access changes. According to the council, from late June to mid-September the road closes to cars from 8:30 to 17:30, and the tourist board adds that in those months the stretch up to La Coma del Forat is kept for cyclists riding up to the Port d’Arcalís. Your way up is the Tristaina gondola, about ten minutes from l’Hortell to La Coma. Lift times and prices are on the resort’s website. The Comú d’Ordino puts the parish about 170 km from Toulouse airport and 200 km from Barcelona El Prat, so doing Tristaina as a day trip from the airport is a stretch. I’d sleep in the valley the night before and be at the gondola when it opens.

The walk, step by step

The tourist board’s loop is 4.39 km from the car park at the La Coma service area, with 210 m of total ascent, constant ups and downs and a high point of 2,330 m at Més Amunt. It’s graded moderate, suitable for walkers of all levels, and takes about three hours. The stretch to Estany Primer, about 40 minutes, it rates as easy and suitable for children.

The council offers a shorter version. It starts at a small picnic area about 300 m past the Arcalís 91 sculpture, is marked with yellow dots, and runs 3.5 km there and back with 130 m of ascent in 1 hr 40. You can also climb from the path beside the La Coma d’Arcalís restaurant.

Can you swim at Tristaina?

Yes, with caveats. According to the tourist board, you may bathe at Més Amunt in the summer months. It’s high mountain water, so I’d keep it for a hot day around midday. As everywhere in the Andorran high country, wear proper boots and carry a warm layer, because the official listing warns that the weather turns quickly. And since gov.uk says the GHIC isn’t valid in Andorra, make sure your travel insurance covers mountain walking.

Outside the summer

The good window is short. The tourist board treats high summer as the season for routes above 1,700 m, and in spring or late autumn snow can still lie on the path. In autumn, once the road closure lifts in mid-September, you can drive to La Coma again, which I think is the best time to go without crowds. In winter the lakes lie within the ski area under snow, and the resort runs guided snowshoe outings towards the viewpoint or the Port del Rat. For a sense of the crowds, Ordino Arcalís counted over 60,000 visitors between 6 June and 13 September 2026, so in August I’d be on the first gondola.

My verdict and how to round it off

For me Tristaina is the best effort-to-scenery ratio in Andorra. I’d go early, do the full loop without rushing and, if the sky stays clear, take the Creussans chairlift up to the Tristaina solar viewpoint, which looks down on these same lakes from 2,701 m. If you want more, I compare the rest of the country’s lakes in lakes in Andorra.
