Château Saint-Martin & Spa, Oetker Hotels

Between Vence's medieval hill town and the Baie des Anges coastline, Château Saint-Martin occupies a 12th-century Templar commandery on Avenue des Templiers, its stone bastions surveying fourteen hectares of olive and cypress above Nice.

The spa draws on the estate's own olive oil in several treatments, with a hammam, sauna, and indoor pool separate from the outdoor terrace pool that faces the Alpes-Maritimes ridge. Tennis courts, yoga classes, and a personal trainer round out the wellness offer without sharing facilities with day visitors.

The property sits roughly twenty minutes by car from Nice Côte d'Azur airport yet registers no aircraft noise — the Var valley absorbs it. Check-in opens at 15:00; late check-out to 12:00 is standard.
