Deep Blue Hotel & Hot Springs
At 1 Worm Bay Road in Warrnambool, the Deep Blue sits right where the land runs out. The coast is the backdrop; the pools are fed by geothermal mineral water drawn from deep underground. It works as a hotel stay, a day trip, or something in between.
The Hot Springs Sanctuary is the main draw: open-air and indoor pools, cascading thermal waterfalls, and water that’s mineral-rich by description, though the specific composition isn’t published. If a particular mineral is what you’re after, it’s worth a call before you book. What’s not in question is the setting. Outdoor pools with an unobstructed view of the Southern Ocean is a reasonable argument for making the drive to Warrnambool.
Outdoor pools, geothermal water drawn from deep underground, and the Southern Ocean right there as backdrop.
Inside, the Sanctuary runs to sensory caves and a salt therapy room. The salt therapy session goes for 45 minutes and pairs guided meditation with salt air exposure. It’s the quieter option, worth building into a longer visit rather than treating as an afterthought.
Sessions are structured and timed across the day. The twilight slot (7:30pm to 9:30pm) is adults and older teens only, which tends to make it the calmer end of the day. Entry includes robe, towel, and locker hire, so your bag can stay light. Non-slip footwear is required, glassware is out, and a shower before you get in is compulsory.
Robe, towel, and locker hire are all included, the list of things to pack is genuinely short.
Children under 5 can’t use the Sanctuary. Kids aged 5 to 15 are welcome at day sessions, with an adult within arm’s reach throughout.
Day access starts at $55 per adult through the Breakfast & Bathe package, or $68 per adult for Soak & Graze, which adds a food component and a 2:30pm to 4:30pm soaking window. An evening tasting and hot springs stay begins at $645, and a twilight ritual with a chef’s tasting menu is available as an $85 per person addition. Overnight packages, which include the hotel and indoor pool access, start at $449 Sunday to Thursday and step up from there on weekends. The hotel holds a 4.3 rating across more than 1,600 Google reviews.
Book ahead, particularly for twilight sessions and weekends. Those slots fill up, and the timed structure means there’s no casual walk-in flexibility once a session is full.
