I had the experience of playing at the labyrinth park in the border triangle Aachen. Have you ever played in a labyrinth park? It turned out that getting into the maze and finding the exit was exciting and thrilling. Therefore, it is best if we do not play alone but have a partner with whom we can find the exit from the labyrinth together.
If you want to be in three countries in European countries at once, just go to the border triangle or tripoint near Aachen. When you stand at that point, you will be in Germany, the Netherlands, and Belgium.
