City: Leersum Length of route: The route is 18.4 kilometers long. Environment: The route is located in a vast forest area on the Utrechtse Heuvelrug. Originally these were two estates, namely the Amerong forest and the Zuilenstein forest. The area consists mainly of coarse pine forests. Nature of the route: By the end of 2015, the two old routes of Leersum were merged into one major route of 18.4 kilometers. The part in Lombokbos (at the parking lot on the Utrechtse track) has been completely renewed and contains beautiful long singel tracks and a lot of heightmeters. Marking: The route is marked with wooden poles with a bevelled head with red in the international MTB sign (triangle with 2 rounds).
