The Pertouli ski centre is a modest but functional mountain resort with two lifts, a handful of runs, and the refreshingly uncrowded atmosphere of a place that hasn't been discovered by the package tour market. The season runs roughly December to March depending on snowfall, which is generally reliable at this altitude. Runs suit beginners and intermediate skiers; there is nothing extreme here, but the mountain scenery is dramatic.
The resort has two chalets offering food, warming drinks, and equipment hire. Given its proximity to Trikala and Thessaloniki, it tends to fill at weekends but remains calm midweek. If you are used to Austrian or Swiss ski resorts, this will feel very small; if you want a Greek mountain experience without the crowds of larger resorts like Kalavrita, it is exactly right.
