The length field round is predestined for a family trip, also with the e-bike. The route runs in the valley floor on gravel roads and few asphalt paths.Start is in Huben, a few kilometers from Längenfeld towards Sölden. Away from the main road all the hamlets of the valley are explored, from Huben down to Winklen. The trail usually leads along the foaming Ötztaler Ache, where even on hot summers a cool breeze blows. There is also a lack of refreshments on the route. Sufficient time for stops should therefore be planned.
