This Cradle Mountain to Strahan self drive itinerary runs across the Alpine Plateau, drives through old mining towns, then drops down to the wild west coast at Strahan. It is only in the last 50 years or so that the main roads came to this part of Tasmania. You will be driving through landscapes almost untouched by modern civilization.
While you can drive it in about 3 hours without stopping, taking a full day and poking around in the back blocks of the small towns makes for a good time of it.
This will give you a good appreciation for the early settlers who braved the weather of Tasmania’s west coast to mine for silver, lead and zinc in really harsh conditions.
