About Deep Blue Hot Springs
Deep Blue Hot Springs, Australia is a paid geothermal spa sanctuary at Worm Bay Road in Warrnambool, Victoria, situated at the western end of the Great Ocean Road on the state's south-west coast. The facility draws mineral-rich water from 850 metres below the surface, delivering it into 18 distinct bathing experiences across an open-air rock pool environment. These include 17 thermal pools ranging from 35 to 41 degrees Celsius, sensory caves with chromotherapy lighting, cascading thermal waterfalls, a cold plunge pool maintained at 12 to 14 degrees Celsius, and an aroma pool with jasmine plantings. An indoor bath house and private bathing rooms are available separately.
The Sanctuary, as the complex is called, is designed as a self-guided experience. Visitors move between pools, caves, and waterfalls at their own pace over a timed session. The facility was developed as part of the broader Deep Blue Hotel complex, which includes an 80-room hotel with coastal views, a day spa, a restaurant and cafe, a salt therapy room, and an indoor swimming pool. For visitors exploring geothermal pools in Australia on the Great Ocean Road, Deep Blue is the primary thermal bathing destination in Victoria's south-west and offers one of the most architecturally developed hot springs environments in the state.

The session duration is timed, so arriving punctually at the booked start time is important to use the full allocation.
Safety & Etiquette
Deep Blue Hot Springs Safety Tips
Deep Blue Hot Springs is generally safe for most visitors. The facility is staffed, the pools are regularly tested, and the water quality is monitored to maintain safety and cleanliness. Pool surfaces and walkways can be wet and slippery; appropriate footwear is recommended throughout the Sanctuary. The cold plunge pool operates at 12 to 14 degrees Celsius, which is significantly colder than the thermal pools; those new to contrast therapy should enter slowly and limit initial cold immersions to short durations. Long periods in pools at the higher end of the temperature range should be broken up with cooler sessions or rest breaks outside the water.
Pregnant visitors are advised not to bathe in the hot pools; the facility recommends consulting a medical practitioner before visiting. Visitors with open cuts or wounds should not enter the pools. Dark-coloured swimwear is recommended as the mineral water can discolour lighter fabrics. Soaps, oils, and sunscreen should be applied after, not before, entering the pools. The facility requests that mobile phones be set to silent inside the Sanctuary and that photography remain focused on one's own group with consent.
Sessions are fixed duration and entry cannot be extended if a visitor arrives late. Booking in advance is essential, particularly on weekends, public holidays, and during school holidays when the Sanctuary reaches capacity. Food is not permitted inside the Sanctuary; the on-site Tides cafe and bar is available before or after a session. Water in non-glass refillable containers is permitted inside. The Sanctuary closes temporarily during lightning or thunder; this does not extend the booked session time, so checking the weather forecast before visiting during unstable conditions is advisable.
