The abbaye is located 8KM away from my parent's place through the woods.

Roadbook O2Bikers numéro 63

I cannot find the GPS tracks on the O2Bikers.be website, neither on the Randobel.be website.

The description of number 63 is "Road-book: Pèlerinage gaumais à Orval".

The roadbook passes by 3 religious points of interest: Orval-Avioth-SaintWalfroy

FFC marks

There are some FFC signs just 300m from the road Orval-Virton, they are parts of tracks on the french side which covers nearly the same territory of the circuit published in O2bikers number 63:

Those FFC marks have dissapeared last time I rode this track.

GPS traces

Question is how to display such trace on OSM with a map as overlay?
