From Girona · 41.98° N · 2.82° E
Two getaways with a night away and five day trips from Girona for 15 August, the Assumption, designed to turn your back on the full coast: Núria lake, the Ripollès greenway, bends at 1,900 metres, shady beech woods and cool cellars underground.
Map

In August Núria is at almost 2,000 metres and several degrees cooler than the coast, with the lake and the meadows in summer. The Rack Railway has its long timetable and fills by mid-morning: buy the train online and go up on one of the first.

When the coast boils, the Ripollès gives a Sunday of monasteries under cover and a flat greenway beside the Ter. Both monasteries open in August, and the Ripoll cloister is cool first thing.

In August the Coll de la Creueta, at 1,921 metres, is one of the coolest roads nearest Girona, with a stop in Castellar de n'Hug and the sources of the Llobregat. Set off early: in mid-afternoon the Pyrenean storms build up.

At 1,100 metres and under the beeches, Santa Fe is the nearest shade to Girona in August. The loop round the reservoir is flat and short, and the mountain grill is eaten outside; book, as on the long weekend it fills.

In August the Salt de Sallent carries little water, but the stream has shade and Rupit, at 800 metres, cools in the afternoon. The 1930 inn has a cool stone dining room; closed on Wednesdays.

In summer the balloon goes up with the first light, before the heat, and is the best time to see the volcanoes. Besalú is toured before eleven; the Besalú Medieval festival is at the end of the month, not on the 15th.

The Codorníu cellars are underground and are toured by train at a cool temperature, the plan for the hot hours. Open all year, August too: book the timed visit and lunch at the tower.

Núria, at almost 2,000 metres, the Coll de la Creueta and the Santa Fe beech wood in the Montseny.
Only very early. At midday the beaches and villages are full and parking is difficult.
