See the bus line "Y" timetable
and the arrows to our house on the area map (small,
large) and the CERN-Thoiry map (large,
small).
Coming on the highway from Lausanne
approaching Geneva, the highway splits, take highway to "Geneve Aeroport
Cointrin, Meyrin"
pass airport (on your right), take next highway exit to "Meyrin, St. Genis"
follow Route de Meyrin (big road) for some 5 km to Swiss-French border (fr.
douane), direction to "St.Genis" (the CERN main entrance is just before the
border on your left)
cross border
500 m after the border there is a large round-about, take a left (do not
enter St. Genis)
follow road for 2 km until you reach a second round-about, take a right
(direction "Thoiry - Allemogne")
follow road for 2 km, passing train tracks
upon reaching the T-junction, take a left, enter Thoiry Allemogne
follow road into center of Thoiry
before reaching bar/restaurant, take a right into a very steep road up the
mountain (when you reach the church of Thoiry you're already too far - turn
around and go back 100 m)
after some 500m, take a left and continue up the mountain
after some 1 km take a right into Rue des Terrasses (if you reach a road
sign "Thoiry End" you are already 20 m too far)
Tip: It is the last row of houses up the mountain of Thoiry (Les Hauts de
Thoiry - Les Terrasses de Thoiry), before the forest and the nowhere starts,
so in case you miss it you'll quickly notice and turn back, then take the
first road to the left.
Good luck!
Coming from CERN
Same as "coming from Lausanne" (see above), except that you skip
the first few directions
