Vegetation is not very exciting, like in Switzerland, in a normal forest. The only highlight is the Étang de Bonfol.

In Lucelle you have the possibility to get supplies at the gas station. I didn't see anything to stop by. But I wasn't looking for it either. At the lake there are benches in the sun and in the shade. The fauna on the lake was rather sparse. The small stream with the tiny waterfall is quite picturesque. But the place is nice for a short rest and pause.
