Map

From March to May the Monfragüe birds are nesting: griffon vultures occupy the Salto del Gitano wall and, with luck and binoculars, black stork, Egyptian vulture or imperial eagle can be seen. In spring the park also runs free guided walks. Book the rural house and the Sunday 4x4.

From February to July lesser kestrels nest on the roofs of Trujillo's Plaza Mayor, and in May you see them hunting over the square at any hour. The morning guided visit bundles four tickets for €18. The afternoon, sitting in the square, looking up.

In spring the Villuercas have green ranges and full streams, and it is one of its two best seasons, with autumn. Two nights beside the monastery allow for the guided visit, the hermitage and a walk. The vulture hide is booked beforehand.

In spring the Almendres cork-oak grove is green and flowering, and it is the best time to spend three hours in the countryside with the archaeologist. Groups are of 3 to 7 people: book. 1 May is also a holiday in Portugal, and Évora receives many Portuguese visitors.

The path from Castelo de Vide to Marvão is almost ten kilometres among chestnut trees, and in spring the countryside is green and the sun not yet oppressive. It is not done in July and August: almost all in the sun. May is one of its best months. Remember: in Portugal, one hour earlier.

The Convent of Christ is closed on 1 May, so if the long weekend starts that day, leave Tomar for the second and do Almourol and the Pegões first. From April to June the Tagus and the Castelo de Bode reservoir are at their best for the boat.

Spring is one of the best seasons for the Alqueva sky, with mild nights for being outdoors. The Cumeada telescope sessions run Tuesday to Saturday: choose the night and check the moon phase, because with a full moon you cannot see the Milky Way.

In spring Jerez de los Caballeros is toured without summer's heat, between the towers of San Miguel and San Bartolomé and the Templar fortress. The Museum of Sacred Art, with Jerez's Holy Week, opens on Sunday from 10:00 to 14:00. An hour from Badajoz.
