Koli is one of the closest ski resorts to Helsinki. Its Ukko-Koli ski area has six steep, challenging slopes (three illuminated), the longest of which is 1500m, serviced by four lifts. Over 60km of cross-country trails include 22km of lit track. Ski-school lessons cost €46 per 50 minutes.
There's an additional, one-off €6 charge for the rechargeable lift ticket, valid at most other Finnish ski resorts.
