Great Artesian Basin Mound Springs vs Artesian Bore Baths: What's the Difference?

Australia’s Great Artesian Basin creates two very different kinds of warm-water experiences. One is natural: groundwater reaches the surface through springs, seeps, pools, and mound-spring systems that have existed for thousands or even millions of years. The other is developed: people drill into artesian aquifers, bring groundwater to the surface through a bore, and direct that water into a pool or bathing facility.

Both can involve naturally warm artesian groundwater. Both can be memorable places to visit. But they are not the same thing. That distinction matters when deciding whether a destination should be described as a natural hot spring, a mound spring, an artesian bore bath, or a developed thermal pool.

Dalhousie Springs

Dalhousie Springs

Dalhousie Springs is a remarkable natural mound-spring complex in Witjira National Park in the far north of South Australia. Fed by the Great Artesian Basin, the springs form a warm-water oasis within an otherwise dry and remote desert landscape.

The main spring is the best-known visitor bathing area. South Australia’s National Parks and Wildlife Service lists its water at around 37°C and permits swimming there, while the surrounding mound-spring system is protected for its natural, cultural and ecological importance. Dalhousie is not a constructed bore bath or commercial thermal spa. It is a natural artesian spring system where groundwater rises from considerable depth through cracks and fissures before reaching the surface.
