Six Senses is known for top-tier, sustainability-focused resorts in far-flung locales like the Maldives but, in 2015, the Bangkok-based hospitality brand opened its first European resort in Portugal’s wine-producing Douro Valley. Housed in a 19th-century manor house with a terracotta-tiled roof, the property features a contemporary interior, outfitted in shades of muted gold, gray, and white. Set high on a hill, the 57 rooms, suites, and villas offer stunning views of rolling vineyards, lush forests, or the property’s courtyard.
For what are undoubtedly the best vistas, choose one of the fifth-floor Quinta Panorama Suites, each with floor-to-ceiling windows that look straight onto the meandering Douro River. A wine cellar and library showcase the best of the region’s vintages, while three restaurants make use of vegetables and herbs harvested from the resort’s own organic garden. Apropos of a spa in wine country, nail treatments come with wine and cheese tastings, and scrubs and masks are individually blended with grapes, salts, herbs, and other natural ingredients.
