To complement natural snow, nearly all trails of the Alpe di Siusi are equipped with artificial snowmaking equipment
. Open reservoirs ensure the water supply. The natural cooling effect achieved through this open storage system makes the construction of cooling towers redundant. The water is distributed to the snow cannons with the help of seven pump houses
equipped with electric pumps. Around 70 snow cannons are currently in use. Most of them are fan guns
, next to a small number of snow lances
. Artificial snow
is made of water and air only. Efficient snowmaking protects the soil and limits potential damages caused by the edges of the skis and snowmobiles.
A lot of attention is put into snow grooming to ensure optimal slopes. About twelve so called snowcats
, with an average horsepower of 400 each, carefully groom the trails on a daily basis, usually between 5pm and midnight. The front blade is used to move and flatten the snow, and the tiller at the rear refines the surface. Does the resort require winch cats
? There is one in use on the Bullaccia, which has one of the steepest slopes of the area (classified black). Winch cats allow grooming to take place on steeper pitches. Through the use of wind-up devices, they pull themselves up the slope with a rope, which makes for a safer and smoother grooming process. To improve the connections between the resort's slopes, recent years saw the construction of underpasses and bridges
at some of the few crossings between slopes and streets.
Certified Green Energy from South Tyrolean hydraulic power, produced without any CO2 emission, is used for the snowmaking process as well as for the lifts - significantly contributing to a sustainable future in that way.
