Maastricht river cruises, Netherlands

What's great about Maastricht river cruises?

Historians can’t make up their minds about Maastricht, which borders Belgium and Germany. Some say it’s the oldest city in the Netherlands, while others reckon the crown goes to Nijmegen. But what’s not up for debate is its locker of centuries-old landmarks, from the Gothic church in Vrijthof Square to the 700-year old tunnels in Maastricht Underground (built for limestone quarrying, not for ferrying commuters around). There’s a modern side to this place, too. The art-filled Bonnefanten Museum, for example, looks like a space shuttle.
