The Spirit of Summer Wellbeing
To us, Theros, the season of summer, heat and harvest, is a state of mind, a concept of life. Our vision is to offer you a holistic experience of island happiness inspired by the concept of Ef-Zin, meaning wellbeing in ancient Greek. It encompasses a lifestyle based on Aristotle’s philosophy of completeness and the pursuit of happiness. In our signature “Ef-Zin” Spa and gym, you are invited to gloriously switch off and find inner peace through immersive experiences that reconnect you with nature.
