Starting at the Marlengo/Marling church square follow the main road all the way to Lana. At the first traffic light first take the Via Cantina street and then turn into Via Monte Leone street, just opposite the new Merano Burggräfler Winery. After a few hundred meters, take a left turn on to a dirt road onto the Via Palade street towards Cermes/Tscherms. Just before the village church, turn left onto the cycle track through the fruit orchards. The track is mostly on dust roads leading through spectacular terrain, as far as the Firmiano/Sigmundskron intersection just before Bolzano/Bozen.
This is the start of the Oltradige/Überetsch cycle track that winds its way along a gentle slope though the vineyards of the upper Etschtal Valley, to Frangarto/Frangart and Girlano/Girlan as far as S.Michele/St. Michael-Appiano/Eppan. On arrival at the Kreuzweg intersection, continue to the Kalterer See Lake or to the village of Caldaro/Kaltern. Kalterersee can be reached following the Ora/Auer cycling track.
This section of the Etschradroute is roughly 42 km long with an elevation of only about 200 m as it descends from Marlengo and only about 75 m to Firmiano.
