FATMAP difficulty grade
A justly popular linear hike of 65 kilometres (40 miles) from Cradle Mountain to Lake St Clair, this trip is even better if you extend it to take in Lake St Clair (Australia's deepest lake) itself, thereby increasing the length to 82 kilometres (51 miles).
Further detours include Cradle Mountain and Mount Ossa, the tallest mountain in Tasmania at 1617 metres.
If you have the time, do all of the extensions and variations - the scenery will always reward your efforts.
Generally the track is good all the way, with long sections of boardwalk and good signposting, but the sections of the walk without boardwalk can be quite muddy so don't wear your best clothes! There is a good network of huts on the track but there is no reservation system so it is compulsory to carry a tent so that you can camp next to a hut if it is full, which they often are.
Even if you do get into a hut there are no mattresses or bedding and cooking facilities - just some flat, dry space and tables to cook at, plus composting toilets and a fresh water supply.
Between the huts the hike takes you through some beautiful forests, valleys and sections of moorland, all under a huge (hopefully blue) sky.
The ascent of Mount Ossa requires some scrambling but otherwise the hiking is not technical or difficult.
Most hikers finish their walk at the end of Lake St Clair and take a ferry back to civilisation from there but in return for one extra day of effort, you can walk the length of the lake all the way back to the roadhead.
