Given that Greece is a predominantly mountainous country, its features include many hills and slopes, which in the ski season, which runs from December to April, receive a fair amount of snow. Worth noticing, however, is that only in mainland Greece can one find snowy mountains since, in the islands, the weather is so good that many even swim year-round! As a result of the high altitude of the mainland mountain chains, nonetheless, Greece offers a variety of ski resorts to choose from. Skiing in Greece attracts both ski and snowboard lovers— adrenaline seekers and even professionals— but its mountains cater to the interests of those who wish to take in the wintry landscape during a smooth slide. Several skiing options of varying difficulty can be traced across the country. All in all, there are over 195 kilometres of pistes, meaning tracks of solid snow accompanied by over 120 ski lifts. Moreover, during the past years, a number of heliskiing opportunities have risen in popularity, allowing visitors to fully experience the panoramic mountainous landscape and try off-trail hills covered in untouched snow. Most of the ski resorts in Greece are easily accessible from an international or regional airport. Mountain Parnassos, one of the most popular ski centres, is conveniently located just two hours from Athens.
