Park your car at the valley station of the Haunold chairlift or travel there by bus. The hike begins by going up to the tennis courts and then walking towards Dobbiaco on trail no. 28A to the source of the Drava. The nicest way to return is along the same route. Alternatively, you can continue on the same trail to Dobbiaco railway station (a further 45 minutes). From there you can easily return to San Candido by train.
