Variation: A return trip to the Grande Carrière (+ 2 km, + 1 hr)

500 m further on, you will come to the quarry trail marked. Take the trail to the left, leading to the site of the old Struthof quarry. The path is very steep! Then retrace your steps to continue on your way.

i The granite stone from the Natzwiller quarry has an unusual pink colour (it is generally grey in the Champ du Feu range), which the German authorities wanted to mine in 1939-1945.
