The best driving routes through the Sierra de Gredos

Sierra de Gredos driving routes are among the best in Spain. Clean corners, well-kept tarmac, light traffic and breathtaking scenery. From La Adrada, home of Gredos Garage, four routes any enthusiast should try at least once.

I have driven these roads hundreds of times. With classics, moderns, rain and sun. Here are the four that best combine driving, beauty and worthwhile stops. Real kilometres, real times, real interest. No filler.

Best time for these routes?

April to October. Spring and autumn are magic. Winter only if you know snow driving.

Fuel stations in mountain routes?

Few. Refuel in Arenas, El Barco or Piedrahíta.

Are roads in good shape?

AV-923, AV-903 and AV-931 are well maintained. Watch for loose gravel after spring storms.
