Gunns Plains Cave is a limestone show cave, near Gunns Plains in the midlands of north Tasmania, twenty kilometres from Ulverstone.HistoryThe cave was discovered in 1906 by a local Gunns Plains man, Bill Woodhouse, while hunting for possums. A possum eluded him down a hole which led him directly to the cave. This opening served as the original entrance to the cave and early tourists needed to descend by rope from it, three stories to the cave floor. 54 steps were later constructed from concrete, leading from the natural cave floor to a new entrance cut into the hillside. This steep and narrow staircase still exists in its entirety and remains the only public entrance and exit to the cave.Because candlelight and torchlight were troublesome, power and fixture lighting was installed throughout to illuminate the walking track and the cave's unique features. In 2003 the system was updated to be of more benefit to visitors.As of 2004 the cave is maintained on behalf of the Tasmania Parks and Wildlife Service by Geoff and Patricia Deer, who lease the rights to manage the cave. There are daily tours.FeaturesThe public section of the cave runs 275 metres, is well lit and is for the most part a simple walk. The only hazard lies in taking caution of low ceilings and protruding walls. Aside from the entrance staircase and the occasional step, there is a small permanent ladder used to navigate through one narrow gap.Many beautiful cave formations are present, such as stalactites, stalagmites, helictites and a large array of dazzling flowstone are present in the public section of the cave.
