The Maastrichterallee is an ascending Lindendreef with a length of 600 meters.

The Maastrichterallee connects the gatehouse of Alden Biesen with the guest house, representing a height difference of thirty meters and an average gradient of 4 and a maximum of 6 percent. This Lindendreef is about 600 meters long, consists of two parts and was for a long time the main avenue to the castle. The name of the avenue (reference to Maastricht) has nothing to do with nearby Maastricht itself, but with Nieuwen Biesen, a commandery of the knights of the Teutonic Order in Maastricht that was subordinate to Alden Biesen and of which almost no traces remain today. . The cobbled road was built at the end of the sixteenth century under Commander Heinrich von Reuschenberg. In the part that departs from the guest house (now catering) Maastrichterallee is bordered on one side by a wall with an orchard and agricultural area behind it, on the other side you have buildings and an entrance to the courtyard of the commandery.
