Ipswich to Sion Road Trip: Ultimate Guide

The road from Ipswich, England, to Sion, Switzerland, spans approximately 700 miles (1127 km) and crosses three countries. A unique aspect: you'll traverse the Channel Tunnel, the longest undersea tunnel in the world, connecting Folkestone to Calais in just 35 minutes. This journey shifts from the flat Fenlands of East Anglia to the dramatic Alpine peaks of Valais.

Your journey starts in the Suffolk countryside, crossing the Thames Estuary into Kent's Garden of England. After the tunnel, you'll pass through the Champagne region near Reims, where the rolling hills are punctuated by vineyards. Then, the Jura mountains and finally the Swiss Alps dominate the horizon as you approach Sion.
