My Strahan to Hobart self drive itinerary climbs up into the mountains to Queenstown, then across valleys and more mountains on the Alpine Plateau to Derwent Bridge at the southern end of Lake St Clair.
The Derwent River rises here, and the drive passes through the Hydro Electric generating area and follows the Derwent Valley downhill all the way to Hobart. Visit Russell Falls on the way.
Allow a full day of it to drive from Strahan to Hobart. It can take up to about 10 hours, depending on how much you decide to stop and look around. To drive right through with only small stops will take about 6 hours.
