Three getaways with a night away and four day trips from Tarragona for 1 May, Labour Day: the Priorat in the week of the Falset Wine Fair, the Escaladei charterhouse, the Siurana reservoir, the unspoilt Irta coast, a Penedès cellar and the Garraf coves.
Map

The Falset Wine Fair usually falls on the 1 May weekend, twenty minutes from Escaladei, with the wineries of the Priorat DOQ and the Montsant DO in the street. The charterhouse closes on non-holiday Mondays: on 1 May it opens even if it is a Monday.

In April and May the Gratallops vines have new leaves and the winegrowers come out to show them. Tastings are not held on Wednesdays; in Wine Fair week, book both wineries before going.

The kayak on the Siurana reservoir opens on spring weekends, and in May the Trona ledge is done without the summer sun. The 4x4 route goes out with a single vehicle: on a long weekend, book it first.

In May the Sierra de Irta has the track open without July and August's booking, and the water already invites you to dip your feet. The castle is visited in the morning; Casa Jaime only takes phone bookings, and on the long weekend it fills.

On spring Sundays the Penedès wineries with tables fill, and a May holiday is like a Sunday. Book visit and lunch with days to spare; from Tarragona you get there by train, with a change to the R4 at Sant Vicenç de Calders.

In May Garraf is still a village of huts and coves without summer's collapse, and the path above the sea is done without heat. Go by train and early; the rice facing the beach is booked.

At a thousand metres, Prades has in May the oak woods with new leaves and the square's fountain in the shade. The walk to the Roca Foradada is short and flat, for all ages, and the inn fills on holidays.
