We will be staying at Tongariro Crossing Backpackers around Easter time for 2 nights, arriving from Taupo airport and want to do the full day hike including Ngauruhoe. I was wondering which was the best 'way' to do this, eg. start and finish. We have a car, but again, unsure of parking, etc... as I've seen some warnings too. We'd like to do this early to avoid crowds, any recommendations of times, etc?
