Tantanoola Caves Conservation Park
Pink dolomite show cave
schedule 1 min read / Updated Jun 2026
Tantanoola Cave is a compact show cave northwest of Mount Gambier on the Princes Highway, renowned for its unusually coloured pink and brown dolomite formations and the distinction of being the first wheelchair-accessible cave in Australia. Guided tours through the single chamber reveal speleothems shaped in dolomite rather than the more common limestone.
The cave was discovered in 1930 by a local boy and opened for tourism not long after. In 1983, ramps and modifications made it accessible to wheelchair users and people with prams, a significant achievement for cave tourism in Australia at the time. The cave sits within a 14-hectare conservation park.
Formed within an ancient marine cliff of bryozoan dolomite, the cave's distinct pink and caramel hues set it apart visually from the grey limestone caves common elsewhere on the Limestone Coast. Guided tours take around 30 minutes and run throughout the day, with interpreters explaining the geological and natural history of the formation.
The park has picnic facilities, a children's play area, accessible toilets, and a clifftop walking trail with views across the coastal plain. Online booking is available, and walk-in visitors are welcome subject to capacity.
