Domaine de Grosbois
English Version
This multicache can be found in the Domaine de Grosbois, situated
in the town of Boissy-St. Leger. Easily accessible by car or RER
train from Paris. If coming by train, take the RER A east to the
end of the line at Boissy-St. Leger. From there it's about a
15-minute walk up Rue de Paris to the forest.
This is a 5-part cache; to complete it you must visit 4
waypoints to gather coordinates for the final cache (A-J. Waypoints
can be done in any order; the way I have laid them out is the most
logical, however.)
N 48° AB.CDE E002° FG.HIJ
1st Waypoint
N 48° 44.825
E002° 30.924
You will find a posted map of the forest at this location. In
what year was the map placed? year=HJxG
2nd Waypoint
N 48° 44.516
E002° 31.341
You will find a single-digit number painted on a tree at this
spot. number=F, F+1=A
Since people are having trouble locating this
tree, I'm going to help you out. F=3!
3rd Waypoint
N 48° 44.628
E002° 31.456
Another single digit number, this one is painted on the trail
itself. number-3=E
4th Waypoint
N 48° 44.755
E002° 31.456
Here you'll leave the main trails to find a tree marked with a
two-digit number. The tree will be visible on the other side of the
fence from your location. number+58=CD
You were wondering about B and I?
B=A and I=G...go find the cache!
