From Lleida · 41.62° N · 0.62° E
Three getaways with a night away and four day trips from Lleida for 15 August, the Assumption, when the plain goes above 35 degrees: high-mountain lakes in Andorra, the water of the Garonne and Collegats, the Perseids over the Montsec and forests and rivers for the hot hours.
Map

July and August are the months for this getaway, with the Tristaina lakes free of snow at over 2,200 metres and the afternoon in Caldea. In August there are storms almost every afternoon: start the lake circuit first thing.

In August Garonne rafting is in full season, from age six, and in the Val d'Aran it is considerably cooler than on the plain. Book rafting and lunch first: it is the most requested day of the summer in the valley.

In July and August the Lakes Train is the panoramic one, leaving at 10:47, and Collegats rafting runs Monday to Saturday. If Sunday is the river day, swap it for Saturday or do the via ferrata.

The Perseids peak in mid-August, and the Montsec sky is a Starlight reserve. By day, the Mont-rebei gorge is in the sun: start at eight and book the La Masieta car park up to the night before.

At a thousand metres, Prades and its Pyrenean oak forest are among the coolest places near Lleida in August. The walk to the Roca Foradada is short and the cave hermitage cool: go in the morning.

In August the Parrizal is a walk beside the water and in the shade of the cliffs, with the summer ticket and an hourly quota. Buy it beforehand and enter early; dogs may not pass.

The Codorníu cellars are underground and are toured by train at a cool temperature: it is the plan for the hot hours. They also open in August; book the timed visit and lunch at the tower.
