Cercedilla is where Madrid goes to walk: the last stop of the C-8 Cercanías before the rails turn into the little C-9 mountain line, and the trailhead for the Fuenfría valley — a glacier-cut amphitheatre of Scots pine crossed by a genuine Roman road that carried legions over the pass to Segovia. The town itself is an unpretentious sierra pueblo of granite houses, hiker cafés and weekend chocolaterías.
As a base it's the practical choice for walkers without a car: trails leave from the station area itself, the Camino Schmidt and Siete Picos start up the valley, and the C-9 rail line lifts you to the Puerto de Navacerrada and Cotos for the high routes. Beds are simple, honest and cheap by sierra standards.
Fuenfría valley Roman loop — 10 km · 3.5 h. Puricelli info centre → Calzada Romana up to the Puerto de la Fuenfría (1,796 m) → return by the Carretera de la República forest track past the miradores. The full valley: legion road up, painters' road down.
Cercanías C-8 from Atocha/Chamartín (~1 h 20); the C-9 mountain line to Puerto de Navacerrada and Cotos leaves from the same platform (check winter timetables). Drivers take the A-6 + M-622 (55 min). Trails start from town — no car needed at all.
Near the station puts every trailhead and both rail lines at your door. Up the Carretera de las Dehesas gets you into the pines themselves — a handful of hostals sit right on the valley road. Book ahead for autumn weekends, when half of Madrid comes up for the leaf turn.
