The Sierra Nevada ski season will start on December 1 this year.

A heavy snowfall at the resort last Thursday left between 10 and 15 cms of snow and work has started to prepare the pistes for the start of the season.

120 snow cannons have been working since Friday given the ideal temperature conditions.

It’s not yet known how many kilometres of pistes will be open initially; that depends on any further snowfall before the end of the month.
