Ski run provided with a means for preserving snow on the skiing surface, said means comprising at least pipes suitable for the flow of a cooling agent for cooling the snow present on the skiing surface, said pipes ( 1 ) being embedded and located in a layer ( 5 ) enabling, when the layer ( 5 ) has a temperature of at least 2° C., a water percolation through the layer ( 5 ). Below the layer ( 5 ), a draining system ( 6,7 ) is placed for collecting and draining at least substantially all the water percolating through the layer ( 5 ) in which the pipes ( 1 ) are embedded
