Map

The Lakes Train opens its season in April and runs on spring Saturdays from Lleida. With the return ticket you can come back on a regular train of the line within six days: book the via ferrata first and then the train.

In May the canyon season begins in Guara, with the Vero carrying the winter's water. The companies set the departure according to the flow: book it on the condition of being able to change day, and the walkways with a time.

From April to June the Añisclo canyon runs with meltwater. The HU-631 is one-way in high season: check the year's dates. Go in in the morning, when the road is quiet, and book Sunday's canyon before leaving.

In May the Matarraña is green and the Parrizal river carries cold, clean water. The walkways ticket is bought beforehand with a time and on a long weekend it sells out; the 4x4 to the Ports, also booked.

The La Masieta car park, the entrance to Mont-rebei on the Lleida side, opens on weekends and holidays, and in May the gorge is done without the heat. It is booked up to 23:59 the night before: do it after the Astronomical Park session.

At a thousand metres, Prades has in May the oak woods with new leaves and the path to the Roca Foradada still cool. The walk is short and easy, for all ages, and the village inn fills on holidays.

In May the vines on the Camí del Vi have leaves and the family winery opens its terrace for the aperitif. The train from Lleida reaches Vilafranca with one change; booking is essential on a holiday.
