Segovia is an excellent city for walks. Drop down onto the path that winds its way down into the valley from the Alcázar on the north side of the city wall and you’ll reach the Río Eresma. Head west and you’ll pass close to Vera Cruz and the Convento de los Carmelitas, with some great views of the Alcázar, before turning back towards the city; head east and you can follow the beautiful tree-lined path alongside the river and wend your way back up the hill to the old town in a round trip of a little over an hour. On your way round you can visit the Monasterio de El Parral (July & Aug Tues 4–7pm, Wed–Sun 10am–2pm & 4–7pm; rest of year Tues–Sat 10am–12.30pm & 4.15–6.30pm, Sun 10–11.30am & 4.15–6.30pm; donation); or better still, follow the track that circles behind Vera Cruz to the monastery. El Parral is a sizeable and partly ruined complex occupied by Hieronymites, an order found only in Spain. Ring the bell for admission and you will be shown the cloister and church; the latter is a Late Gothic building with rich sculpture at the east end. Gregorian Masses can be heard during the week at 1pm in spring and summer and on Sundays at noon.
For the best view of all of Segovia, take the main road north for 2km or so towards Cuéllar. A panorama of the whole city, including the aqueduct, gradually unfolds.
