What is the Deep Blue Hot Spring in Warrnambool?
About the sanctuary
Deep Blue Hot Springs is a coastal geothermal bathing complex attached to the Deep Blue Hotel & Hot Springs, situated on Worm Bay Road in Warrnambool. The open-air sanctuary comprises multiple geothermal pools, including sensory caves, shallow reflection pools, a cold plunge pool (around 14°C), and a rainforest cave-style pool with waterfall features (Finding Alexx). The complex also includes an indoor Bath House facility that offers shorter, lower-priced sessions separately from the outdoor sanctuary.
Geothermal mineral bathing explained
Unlike artificially heated pools, Deep Blue draws its mineral water from the Dilwyn Aquifer roughly 850 metres beneath the surface. The water is naturally heated by the Earth’s core and then managed before being fed into the pools. Vacations & Travel notes that the geothermal water temperature sits around 38–40°C in the warmer pools, while the cold plunge provides a contrasting 14°C experience. This combination of temperatures, alongside the coastal setting, sets the experience apart from inland hot springs.

The Deep Blue Hotel & Hot Springs achieves an 8.2 out of 10 (“Very Good”) on Expedia from roughly 1,000 guest reviews, with frequent praise for staff helpfulness and beach proximity (Expedia).
Common praise points
Multiple reviewers highlight the ocean-adjacent setting, the variety of pool types (especially the sensory caves and waterfall features), helpful staff, and the overall relaxing atmosphere. The coastal air and proximity to Warrnambool’s foreshore walks are frequently cited as enhancing the experience.
