The Tantanoola Caves Conservation Park is a 14-hectare (35-acre) protected area near Tantanoola in the Limestone Coast tourism region in the south-east of South Australia. The conservation park preserves two main caves; the wheelchair accessible Tantanoola Cave which is developed as a show cave and Lake Cave which is a restricted access cave used by the Department for Environment and Water scientists as a reference site for other karst features in the region. Visitors can explore the information centre and learn about the caves during a guided tour.
