The ‘lost world’ on the eastern face of Mount Arthur just short of the summit, which sits at 1,188 metres above sea level. The feature is an organ pipes formation (similar to that with the same name at Mount Wellington) made from dolerite and which has survived the millions of years of erosion of the mountain.
The view from the lower mountain slopes looking toward Launceston in the distance. The mountain is about an hour drive from the city. Hikers usually proceed to the small local township of Lilydale and then by car to the start of the walking track for the mountain.
