We are planning to go to Mt Ruapehu this weekend. Based on the reports this past few days, 4WD with chains is required from Whakapapa going up. My question is what options do we have given one of the cars is not 4WD. Is there a shuttle to go up which would allow us to park in Whakapapa village and avoid the need use chains? I tried to search online but can only see shuttle service from National Park.
