Access to the field is by 4WD or vehicles that have chains that can be fitted. Please check the conditions on the morning snow report, and read and obey all signs. There is a radio in the Bottom Hut (3km from the ski field), which you can use to contact the Top Hut and enquire about onward road conditions.
It is normally not possible to drive the whole way to the Top Hut. The main car park is located a short walk from the ticket office and Access Tow. From here, you can take the Access Tow up to the Top Hut and main ski field. Note that there is no baggage lift: ensure you use a backpack so you can carry your belongings up the tow yourself.
