A beautiful, tranquil establishment with emphasis on luxurious yet soothing treatments. The design is deliberately soft, with plenty of pastel hues, water features and natural lighting. The spa offers four options: Open Aqua (a hydrotherapy circuit), Open Experience (their treatments), Open Beauty (their cosmetic treatments) and Open Fitness (a gym with state-of-the-art equipment). Open Aqua is highly popular for those looking to unwind: it features pools, underwater massage experiences (spouts, cascades and swan neck jets), a counter-current swimming pool, a Kneipp contrast path, ice pool, hammam and sauna. If you're in the mood for a treatment in the Open Experience section, some stand outs include the Garden of England Rose Restore wrap and Akwaterra massage (as a lovely little bonus, those who book a treatment also have full access to Open Aqua!)
