Interlaken to Bastogne Road Trip Guide: Best Stops & Tips

This 650-kilometer road trip from Interlaken, Switzerland, to Bastogne, Belgium, crosses four countries: Switzerland, Germany, Luxembourg, and Belgium. The drive takes about 7 hours without stops, but you'll want to budget at least two days to explore the highlights.
