Jackeys Marsh is an enclosed mountain valley situated at the base of the most northern edge of the Tasmanian Wilderness World Heritage Area. It has significant natural and cultural heritage values.

From Warners Track at the southern end of the valley you can access the Tasmanian Wilderness World Heritage Area. From Adam's Peak at the top of the track on a clear day you can see far across the Central Plateau Conservation Area.

The slopes of the valley are heavily forested while the valley floor has been used sporadically for farming for the last century. The old growth forests of the valley are very diverse because they contain elements of most of Tasmania's forest communities, from dry eucalypts and myrtle dominated rainforest to alpine and sub-alpine species. The now rare King Billy pine grows on the edge of the Warners Track.

The Jackeys Marsh valley retains the landscape values of 19th Century rural Australia. Winding roads are overhung with trees, meandering creeks support native wildlife and there are no power-lines or intensive agriculture to spoil the soft lines of the valley edge. All householders living within the valley use alternative power for their domestic needs.

A biannual forest festival is held within the valley. The festival celebrates the natural and cultural heritage values of the valley and features guided walks, workshops, entertainment and camping on the banks of Jackeys Creek.
