In its first major development since opening in 2005, the Peninsula Hot Springs on the Mornington Peninsula has undergone major expansion.

The $13 million development, due to open to the public on September 22, means visitors will be able to slip into seven new geothermal pools, indulge in new treatments, and experience the newly built Bath House Amphitheatre.

The outdoor pools will be fitted with underwater speakers, allowing bathers to hear amphitheatre performances without leaving the water. There’ll also be an aquatherapy pool and float treatments available.

An Ice Cave will be set between two and minus 10 degrees, with “snow” falling from the ceiling. More courageous guests can try the deep freeze – set to a very chilly minus 25 degrees – before defrosting in one of two 30-capacity saunas.

Organic produce for three onsite cafes is from a three-acre terraced garden, and there are plans to add teas and medicinal plants to the harvest. There’ll also be a thermal greenhouse and underground “mushroom cave”.

Yoga, pilates, meditation and tai chi sessions will take place in a wellness and activity centre that will double as a meeting space.

Within the next three years, accommodation will be added to the site, which will include glamping, double rooms and private lodges.

The amphitheatre and new facilities will open on September 22. Bookings are recommended.
