The Tarkine region of North West Tasmania contains a number of unique cave systems. There are a series of��extraordinary magnesite karst systems, including unique cave and pinnacle formations at Lyons River and the Arthur River ��� Victory Springs area, including warm springs.
The Tarkine also contains dolomite cave systems in the Trowutta/Sumac/Black River region which features hundreds of sinkholes, including the outstanding sinkhole, Lake Chisholm.��These cave systems are not only unique in themselves, but are also home to extraordinary cave dwelling creatures, such as the bizarre ���troglodyte��� (cave dwelling spider) and other fascinating creatures.
Trowutta Caves are located ��south of Smithton, beyond the beautiful Allendale Gardens,��Trowutta and��Milkshake Hills.��The Trowutta Arch track begins soon after the��Trowutta Caves State Reserve is reached. ��A short 10 minute easy well defined walk leads to the park���s most interesting geological feature - the Trowutta Arch. ��The reserve protects an area of sinkholes covered in temperate rainforest full of myrtles, sassafrass, blackwoods, massive manferns and a variety of other ferns.
