Weeks 8 and 9 are winter holidays for schoolchildren and students. Simpsiö’s opening hours are then Monday to Friday from 10:00 to 20:30, and on weekends from 11:00 to 18:00. The slopes are prepared every evening after closing time with a piste machine so that glittering white slopes are waiting for a new ski day. All lifts and slopes are open and the car park is also in top condition daily.
