The tour, signposted with the new yellow mountain bike destination signs, takes you once around the Achertal valley. Experience the multifaceted landscape around the Achertal from the Weibergen up to the Black Forest National Park, Lake Mummelsee and the Hornisgrinden. The 52-kilometre panoarama tour can be started from anywhere in Kappelrodeck, Ottenhöfen, Seebach or Sasbachwalden. It is marked in both directions, but if you want to take the Sasbachwalden trails, cycle the tour anti-clockwise. There are marvellous panoramas to enjoy and numerous places to stop for refreshments. If you are travelling by E-MTB, there are several places where you can charge your battery. It is best to take your charger with you.
