Our marathon tour
From the hotel, it goes along the road in the direction of Hintertux (for battery saving, the road is better than along the Bachweg). From there it goes over the Bichlalm in the direction of Sommerberg, where a short rest can be taken if necessary and the batteries can be charged. From the Bichlalm the tour continues towards the Tuxerjochhaus, past the reservoir via the single trail on the Tuxerjoch to Kasern (there are no more charging stations here).
Altitude difference: in total just under 1600 m
