With seven different Intense sessions organised every day throughout the day, you are spoilt for choice for unique, invigorating Aufguss and scrubbing sessions across our saunas.

Apart from Intense scrubbing sessions in the steam bath (both in the swimwear and nude area), during which you do a salt scrub while the Aufguss master turns up the heat by wafting bursts of hot air over you with a fan or by flapping a towel, our other Intense sessions are also well worth a try. Like the Mushara Aufguss session in the African sauna. During this session, the Aufguss master hands out a nourishing cream with ylang-ylang which deeply moisturises your skin. Or the Intense herbal scrub, as part of which you are given a salt scrub mixed with dried herbs such as lavender, thyme or rosemary to exfoliate your skin!
By the way, we don’t just organise Intense sessions. Every day, our wellness programme also features several Ritual and Relax sessions!
