Wasserleitungsweg, the aqueduct path through the Höllental

Since 1998 a trail has followed through the Höllental the line of Vienna's first spring-water pipeline, the one that since the second half of the 19th century has carried water from the Rax and the Schneeberg to the city. It starts at Hirschwang, next to the cable car valley station, and reaches Kaiserbrunn beneath rock walls, beside the River Schwarza: about 4 km and an hour and a half almost on the flat. It is suitable for families and you can return by bus.
