They can be recognised as lush green strips across the otherwise steppe-like Sonnenberg mountain in South Tyrol’s western-most valley system, Val Venosta/Vinschgau. In fact this sunny area receives a third less rainfall compared with Bolzano. Centuries ago the semi-arid climate drove mountain farmers to dig an intricate system of water channels called ‘Waalen’ to irrigate their fields. The water is diverted from streams fed by the run-off from incredibly high mountains encircling the Val Venosta and today the shady maintenance pathways beside the burbling water (‘Waal-Wege’) provide pleasant, relaxing family walks amid the most spectacular mountain scenery. Popular trails are found in Schenna (Marlengo/Marlinger Waalweg), Parcines/Partschins, Marlengo/Marling, Rifiano/Riffian, Caines/Kuens and Lagundo/Algund.
