Valle de la Fuenfría

The Fuenfría Valley in the Sierra de Guadarrama is one of Madrid's best mountain walking areas. **Trails:** Multiple routes from easy to challenging. The Roman road (Calzada Romana) is historic and scenic. **Mountains:** Real mountain scenery - pine forests, streams, peaks. Cool in summer, snow in winter. **Dogs:** Paradise for active dogs. Off-leash on most trails. Bring water - mountain walking is thirsty work.
