Regina Experimental Biarritz occupies a Belle Époque landmark on the cliffs above the Atlantic, with broad views across Biarritz Bay and towards the lighthouse. Dorothée Meilichzon reworked the 72 rooms around a marine-inspired palette, striped textiles and playful references to the Basque coast, while the soaring central atrium preserves the scale of the original grand hotel. Frenchie Biarritz and the Experimental bar bring much of the social life into that historic volume. Outside, a pool and solarium face the ocean, while the spa includes treatment rooms and a hammam, all within walking distance of the beaches below.
