San Sebastián to Zermatt Road Trip Guide: Spain to Switzerland

The road from San Sebastián (43.3183° N, 1.9812° W) to Zermatt (46.0207° N, 7.7491° E) is a roughly 920 km (572 mi) journey that crosses the Pyrenees, the French Massif Central, and the Swiss Alps. The fastest route uses the A63, A64, A10, and A6 in France, then the A1 and E62 in Switzerland, taking about 10-12 hours of pure driving. But this would skip the Basque coast, the Dordogne valley, and the Rhône vineyards.

• The climb from sea level at San Sebastián to the 1,620 m (5,315 ft) altitude of Zermatt involves a temperature drop of about 10°C (18°F).
• The highest point on the direct route is the Col de la Faucille (1,323 m / 4,341 ft) on the A1 near the Swiss border.
• Zermatt is car-free; you must park in Täsch (7 km south) and take the train.
