The Tongariro Crossing is perhaps New Zealand’s most renowned day hike, leading 19.4km on a one-way journey from Ketitahi Carpark to Mangatepopo. Highly recommended if you’re up for a day’s hiking. Local shuttle services are available to bring you to/from your vehicle, which you park at either end of the trail (most people shuttle first, then walk back to their vehicle along the trail). The Tongariro Crossing is a popular but serious trail, so please prepare accordingly. See the Department of Conservation for details.
