Locarno to Spa Road Trip Guide: Alpine Valleys to Ardennes

The drive from Locarno to Spa covers roughly 700 kilometers, crossing Switzerland, France, and Belgium. A unique quirk: near Andermatt, the Gotthard Pass (not the tunnel) offers a serpentine climb with 40 hairpin turns—a driver’s challenge often fog-shrouded even in summer.

This route transitions from Mediterranean palm trees in Locarno (Ticino) to the dense spruce forests of the Ardennes. Expect a minimum of 7 hours of pure driving, but plan for at least 10 with stops.

For those wondering how long to drive Locarno to Spa, the fastest route via A2, A5, and E42 takes about 7.5 hours without breaks. However, the question is it worth driving Locarno to Spa is answered by the dramatic shift in scenery—from Alpine passes to Luxembourg’s vineyards and Spa’s thermal baths.

Quick Facts
