These narrow paths, which meander along the old waterways, are among the most popular leisurely hikes in Vinschgau. The origins of these canals date back to a time when Vinschgau's farmers had to build irrigation canals to transport water to their fields and orchards. Without the Waale, the rural Vinschgau would often have experienced periods of drought: the climate was dry and rainfall scarce. Today, the caretakers of these waterways are still known as Waaler.
The ancient irrigation canals on the Malser Haide heath are still used to irrigate the crops, like the 400 hectares stretching from Burgeis/Burgusio and Haidersee lake which are irrigated by four canals. It's really rewarding that the masterpiece resulting from this cultural technique has been recognized as an intangible cultural heritage by UNESCO.
