The tour starts from the city centre and takes in some of the key sights before heading out of the town towards the border
The tour crosses backwards and forwards between Germany, The Netherlands and Belgium on its way up to the Dreiländpunkt, the point where all three countries meet.
You have around 20 minutes at the Dreiländepunkt before the bus returns
You can do the tour either as a hop-on-hop-off service, or slightly cheaper as a single round trip, including the 20 minute stop
There is a basic commentary
