A very easy family hike with no significant inclines. The outward route goes almost entirely through woods, a very peaceful setting. The destination is the source of the Drava river between San Candido/Innichen and Dobbiaco/Toblach. You can drink the water directly from the little fountain: you're unlikely to find fresher, clearer water anywhere.
Through the Alta Pusteria/Hochpustertal Valley to Innichen by bus, train or car. From there follow the signs to Monte Baranci/Haunold. Park the car at the parking of the chairlift.
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.
