Two getaways with a night away and four day trips for 15 May, San Isidro, a holiday only in the city of Madrid: the Cervantes Train, Segovia's puppets and the high mountains newly open.
Map
In spring the Cervantes Train sets off from Atocha on Saturdays again, with actors on board and a guided visit in Alcalá, and its season usually runs from April to June. If San Isidro joins up with the weekend, the ticket lets you come back the next day and sleep in the old town.
In mid-May the Sierra de Francia is in full spring, with chestnuts and oaks coming into leaf, water in Las Batuecas and the Peña de Francia already free of snow. With San Isidro next to the weekend there is room for both nights; the Casa del Parque is open Friday to Sunday.

Every May Segovia celebrates Titirimundi, the international puppet festival, with performances in squares, courtyards and beside the Aqueduct, many on the street and free; it usually falls in the middle of the month, near San Isidro. Check the programme and leave the Alcázar for the afternoon.

By mid-May the short route to the Laguna Grande de Peñalara is usually free of snow, and the cirque streams run with meltwater. The Cotos car park has 250 spaces and on a holiday it fills by mid-morning: arrive before nine.

May opens the season for the Laguna Grande in Gredos: the route from the Platform can be done, although in mid-month some patch of snow may remain in the cirque. Ask in Hoyos del Espino the night before, bring poles and book a late lunch of revolconas.

In May the Abantos pine wood is green and cool for climbing before the heat, and the Felipe II Train, the tourist train from Madrid to El Escorial, runs in spring. The 1918 forest lodge needs booking: a holiday in Madrid fills the hills with madrileños.
