Aachen, Germany — Travel ideas

Sitting just across the Dutch-Belgian-German border, Aachen is an effortless international day trip from Amsterdam. It delivers extraordinary medieval history centered on Germany's first UNESCO World Heritage Site alongside centuries-old thermal bath culture and regional spiced pastries, all easily explored entirely on foot.

Overview

Aachen is a historic imperial city with a distinct spa heritage dating back to Roman times. Centered around the grand Octagon of the Aachen Cathedral—where Charlemagne was buried and dozens of German monarchs were crowned—the compact historic center feels like a living museum. A single day trip from Amsterdam gives you ample time to tour the cathedral treasury, sample authentic Aachener Printen gingerbread, and unwind in mineral-rich thermal baths before taking an evening train back.

Getting There

By Train (Fastest/Recommended): Board an NS Intercity train from Amsterdam Centraal down south to Heerlen, then make a quick 20-minute cross-border connection via regional train directly into Aachen Hauptbahnhof (Hbf). Total journey time is roughly 2 hours 55 minutes to 3 hours 15 minutes each way. Alternatively, ICE/Eurostar routes via Brussels or Liège take about 3 hours.
By Car: Drive south via the A2 through Maastricht and cross into Germany; driving time is roughly 2.5 to 3 hours depending on traffic (approx. 240 km).
