Lake Rowallan, Tasmania
Located within 50 metres from the Western side of Lake Rowallan, Old House Creek Falls is the unofficial name of the waterfall that plummets on Old House Creek. The waterfall has two distinct tiers and has a combine height of approximately 20 metres.
Access to the waterfall is along West Rowallan Track, a relatively rough 4WD track that branches off Mersey Forest Road on the northern end of Lake Rowallan. You would need to drive about 7 kms along the track that has sections that are only suitable for 4WD vehicles with good clearance underneath them.
For hikers, it may also be possible to hike into Old House Creek Falls via the Lees Paddocks Track by walking along the Mersey River in a north-easterly direction until it enters into Lake Rowallan. However, this has not been confirmed as yet.
