Snowshoeing is one of the most popular and exciting types of winter recreation. It's the best way to enjoy the snowy silence and spectacular views during your hiking! Moreover, for snowshoeing, you do not need any particular experience, except some general amount of fitness. You just put special equipment on your feet and set off on layers of newly fallen snow through snow-covered slopes, frozen rivers, and high mountain peaks.
In Madrid, the nearest location for such an entertainment is the Sierra de Guadarrama National Park. This mountainous region is particularly amazing in the winter time. If you've already explored it, you can also check out Sierra de Gredos as an alternative. However, it's located a bit further than the Sierra de Guadarrama.
Snowshoeing is normally available from December to April but it always depends on the weather conditions and the snow cover.
