Ski down the deserted slopes.
What is snakegliss?
It's a series of sledges linked together, steered by a driver who will take you down the slopes in a winding fashion according to their whims.
The principle? Maximum excitement for the participants sitting at the back of the train, who may find themselves level with those at the front, while those in the front enjoy a slightly more leisurely ride.
Don't wait any longer; don't let the train leave without you!
