Fodor's Expert Review Ermita de San Frutos
This 11th-century hermitage is in ruins, but its location, on a peninsula jutting out into a bend 100 meters above the Duratón River, is extraordinary. You'll need a car to get there, about 15 minutes' drive west of Sepúlveda. Stay on the marked paths—the surrounding area is a natural park and a protected nesting ground for rare vultures—and try to go at sunset, when the light enhances spectacular views of the sandstone monastery and river below. Inside the monastery, there's a small chapel and plaque describing the life of San Frutos, the patron saint of Segovia. An ancient pilgrimage route stretches 77 km (48 miles) from the monastery to Segovia's cathedral, and pilgrims still walk it each year. As an add-on to the trip, you can rent kayaks from NaturalTur (92/152–1727 www.naturaltur.com) to paddle the river.
