London to Leiden Road Trip Guide: Stops, Routes & Tips

The drive from London to Leiden covers about 350 miles (560 km) via the Channel Tunnel, taking roughly 5 to 6 hours excluding stops. This route crosses three countries: England, France, and the Netherlands. The journey begins on the M20 from London, transitions to the A16 in France, and ends on the A44 near Leiden.
