Pyramidal circuit
Follow the black arrows n°7, some of them are missing (the GPS tracks help to make the complete tour).
There are also a few climbs/descents that are a little technical but short to avoid for real beginners but it's easy to do all the same. Some area a little muddy during rainy periods.
I tried to get as close as possible to the original circuit or the arrows by doing the circuit several times & comparing the GPS tracks recorded and adding the missing paths on OpenStreeMap
(sometimes the path of the map & the arrows differ a little, e.g. from the 1st entrance to the forest, the arrows pass a little lower than the path on the map, so I made a little mix between the 2, which adds a little climb ;) )
