Madrid’s real hiking country is the Sierra de Guadarrama, and you reach most of it by commuter train, not a rental car. The one catch is worth knowing before you plan a whole day around it: the line that reaches the highest terrain has a history of shutting down for years at a time, so verify it’s running before you build a trip around it.
Cercedilla and Valle de la Fuenfría
Cercanías line C-8 runs from Atocha, Chamartín or Nuevos Ministerios to Cercedilla in about an hour, and it’s the car-free gateway into Valle de la Fuenfría, with trailheads a short walk from the station. This is the reliable option: C-8 is a mainline route, not the seasonal branch, and it runs year-round.
Peñalara, the Sierra’s Highest Point
At 2,428 meters, Peñalara is the highest peak in the Sierra de Guadarrama. The standard trailhead is the Puerto de Cotos car park, reached from Cercedilla via the historic C-9 “Tren de la Naturaleza” line, or by road on the M-604 or SG-615. The main route runs about 6km one-way with roughly 600m of elevation gain; a circular variant stretches to about 14km. It’s inside a national park with access rules that shift, so check current trail and permit restrictions before you set out.
The C-9 Catch
Here’s the part most guides skip: the C-9 line from Cercedilla up to Puerto de Navacerrada and Los Cotos, the only public transit route into the high Guadarrama, has a documented history of multi-year shutdowns for maintenance works. If your whole plan depends on reaching Peñalara without a car, check the live schedule before you leave, not the schedule from last year’s blog post.
Manzanares el Real and La Pedriza
Bus 724 leaves from Plaza de Castilla’s underground station, level minus 3, platform 26, and takes about 45 minutes to Manzanares el Real for roughly €4.20, cash only. La Pedriza’s granite massif starts about 15 minutes on foot from the drop-off, and it’s a genuinely different landscape from the pine-forest trails around Cercedilla, all exposed rock and open sky.
El Pardo, Better on Two Wheels
One of Europe’s best-preserved Mediterranean forests, about 15km out, reachable by bus 601, 602, 713, 716, 722 or 724, or Cercanías lines C7, C8A and C8B nearby. Multiple sources describe it as better suited to cycling or running than casual walking, which is worth knowing before you show up expecting a leisurely stroll.
Hayedo de Montejo, the UNESCO Beech Forest
Part of the transnational “Ancient and Primeval Beech Forests” World Heritage Site, added in 2017, and sitting inside the separate Sierra del Rincón UNESCO Biosphere Reserve. It’s guided-tour-only, free, and requires a reservation at sierradelrincon.org, which fills fast during autumn foliage season, or an in-person allocation from 9:30am on the day, covering half the daily passes. The honest caveat: public transit here is weak enough that a car or organized tour is effectively required.
Quick Reference
| Hike | Getting there | Difficulty | Car-free? |
|---|---|---|---|
| Valle de la Fuenfría (Cercedilla) | Cercanías C-8, ~1hr | Easy-moderate | Yes |
| Peñalara (2,428m) | C-9 from Cercedilla (verify running) | Moderate-hard | Yes, if C-9 runs |
| La Pedriza | Bus 724, ~45 min | Moderate | Yes |
| El Pardo | Bus or Cercanías | Easy (better for cycling) | Yes |
| Hayedo de Montejo | Effectively car-required | Easy (guided only) | No |
Before committing to a Peñalara day, check the C-9’s current status on Renfe’s official Cercanías page rather than trusting an old trip report. If you’d rather skip the transit puzzle entirely, book a guided Sierra de Guadarrama hiking day or search a Hayedo de Montejo tour that handles the reservation and the drive for you. For Hayedo de Montejo specifically, book directly through sierradelrincon.org if you’d rather skip a middleman fee.

The honest verdict: Cercedilla and La Pedriza are worth building a day around without hesitation. Peñalara is worth it only if you check the C-9 first, since the alternative is a long, expensive taxi to a trailhead that trains normally reach for a few euros.
