Postcard #5 from Netherlands

St. Petersburg's Cave is definitely the highlight of the trip to Maastricht.

Its underground tunnels are more than 200km long, extending all the way to Belgium.

There was once two boys got lost inside and could not find their way out.

Our tour guide is a local who roamed the tunnels as his childhood playground. That's why he is so familiar with the place.
