From Wim's travel report:
I decide to skip two beacons in Paris and visit RBT and HOL because they are on the west side of Paris.
That fits in better with the plans for the next few days.
Both appear to be in a beautiful area, many forests and several beautiful châteaux can be found here.
HOL is located near the D60 and Les Petites Yvelines and Saint-Hubert.
