A very atmospheric view of Lutzelbourg. A comfortable cycle path with rest stops.

A very well-surfaced road with practically no traffic leads up from Dabo. If you want to continue to the sandpit, you have to take a well-maintained gravel road, which is easier to drive on than some paved roads. At the sandpit, you then meet a paved road again.

Weather permitting, you can enjoy fantastic views from here, for example over the Bruche valley to the south and to the Donon, which is almost as high, to the west.
