From Te Anau, it is 120 km on State Highway 94. Allow plenty of time (and fuel), at least 2-3 hours from Te Anau, when travelling to Milford Sound by car. The road winds through some of the most spectacular scenery in New Zealand as it climbs up to the Homer Tunnel. The Homer Tunnel is a single lane tunnel, although it has been fitted with traffic lights in 2004, you may still experience a wait while opposing traffic clears the tunnel. You may also want to break your journey along the road to take photographs or investigate scenic spots - including Mirror Lakes, views of the Hollyford and The Chasm.

State Highway 94 is a high pass and regularly has icy conditions between June and November. It is also subject to avalanches. All cars must carry chains in winter and the Transit New Zealand information kiosk 8km north of Te Anau will check that you are carrying them and can fit them. High risk sections of the road are marked with a red cross on a blue background and with 'no stopping' signs, do not stop your car on these sections of road. Review the state of the road at Transit New Zealand [2] before departing; if the risk of an avalanche is "high" the road will be closed and if it is "moderate" it may close at short notice. Drivers not experienced at driving on ice and snow might prefer a bus tour. (Wikitravel)
