A nice alternative to the classic ascent via the L86. Coming from Oberachern (south-west), the start is at the entrance to Lauf, at the sports ground car park. From there, turn east onto the small Aubachweg road, then onto Waldstrasse (there are other variants; this is the obvious one). The road is fairly narrow but the surface is good. The gradient is fairly steep (9 to 11％), but less demanding than the L86. In the morning, this road is rather shady, which is pleasant on a hot day. The views... read more

A nice alternative to the classic ascent via the L86.
Coming from Oberachern (south-west), the start is at the entrance to Lauf, at the sports ground car park. From there, turn east onto the small Aubachweg road, then onto Waldstrasse (there are other variants; this is the obvious one). The road is fairly narrow but the surface is good. The gradient is fairly steep (9 to 11％), but less demanding than the L86. In the morning, this road is rather shady, which is pleasant on a hot day. The views over the vineyards and valley are superb.
After around 4km and 330m of ascent, you rejoin the main road (L86) at Bischenberg. This is followed by another 300m of steep ascent (up to 12％) to the plateau at 810m (Grasshohe). You reach the Scharzwaldhochstrasse at around 900m. From here, you can either quickly turn left onto the forest road to climb up to Kleine Grinde (which I always do, as it gives you an almost direct ascent), or you can continue to Mummelsee (1030m) before climbing up to Hornisgrinde (in which case the flat spot on the plateau at 900m is longer and gives you a chance to rest).

Jolie alternative à la montée classique par la route L86.
En venant d'Oberachern (sud-ouest), le départ se fait à l'entrée de Lauf, au niveau du parking des terrains de sport. De là prendre à l'est la petite route Aubachweg, puis la Waldstrasse (il existe d'autres variantes; celle-ci est évidente). La route est assez étroite mais le revêtement est bon. La pente est assez raide (9 à 11％), mais moins exigeante que la L86. Le matin, cette route est plutôt ombragée, ce qui est agréable par forte chaleur. La vue sur les vignes et la vallée est superbe.
Après 4km environ et 330m de dénivelé, on rejoint la route principale (L86) au niveau du Bischenberg. Suivent encore 300m de dénivelé raides (jusqu'à 12％) jusqu'au replat à 810m (Grasshohe). on rejoint la Scharzwaldhochstrasse vers 900m. De là, soit on prend rapidement à gauche la route forestière pour monter au Kleine Grinde (ce que je fais systématiquement, car cela permet une ascension quasi directe), soit on continue jusqu'au Mummelsee (1030m) avant de monter jusqu'au Hornisgrinde (dans ce cas le replat sur le plateau à 900m est plus long et permet de se reposer.

A very nice climb. First through some villages, then through the forest and ending on a clear hill. I did have bad weather, but you seem to have a nice view

Een hele mooie klim. Eerst door wat dorpjes, dan door het bos en eindigen op een overzichtelijke heuvel. Ik had wel slecht weer, maar je schijnt een mooi uitzicht te hebben
