On a hillside above the Aegean in Kassandra, Zélia Halkidiki is reserved for guests aged 16 and over, surrounded by olive groves and facing Mount Olympus. Its 104 rooms and suites use a relaxed contemporary palette, with terraces, sea views, swim-up access or private infinity pools depending on category. The Hebe and Zest outdoor pools both face the sea. Amazonia Spa adds a heated indoor pool, jetted tub, sauna, steam room, sensory showers and five treatment rooms, while the Fitness Hub includes strength, cardio and Pilates equipment. Restaurants draw on Greek and wider Mediterranean produce, supported by a pool bar and café.
