Aurora Spa & Bathhouse, Sorrento

Aurora Spa & Bathhouse is built into the lower level of the InterContinental Sorrento Mornington Peninsula, roughly a 90-minute drive from central Melbourne at the tip of the peninsula. The spa is set below ground, with a series of heated mineral bathing pools, steam rooms and relaxation areas arranged in a subterranean, cave-like layout designed to feel enclosed and quiet rather than open-air like the region's better-known hot springs. The treatment menu runs from therapeutic massage and facials to full body soak rituals that incorporate the property's mineral water, along with guided mindfulness and meditation sessions offered as part of longer packages. Therapists are trained to hotel-spa standard and treatments are delivered in private suites off the main bathhouse circuit, which guests can typically access before or after a booked treatment. Because Aurora sits within a resort hotel on the Mornington Peninsula rather than in central Melbourne, it functions as a half-day or full-day destination for visitors combining a spa visit with wine touring or beach time in Sorrento. Bookings are required rather than walk-in, and the bathhouse itself has capacity limits, so reserving ahead is advisable on weekends when the InterContinental's own guests fill much of the schedule.
