Ad Ketelaars and his website www.offroadtrips.nl are really famous in the Netherlands, but also beyond.
In the Netherlands the motorbike enduro options are not really big, but Ad knows where to find the right trails. He is offering a variety of tracks which you can follow by using a paper-roll, or a Trippy which he rents out, or use your own, at very modest rates.
On his many trips abroad he also created motorbike enduro routes in CZ/Poland, France and Belgium too. 22 tracks in 7 regions. The routes are using legal offroad tracks, so its not hard-enduro style.
As soon as time permits me, I will do one of the tours in the Netherlands and after covid also the Transbelgium one. Reports will follow here.
