Six Senses Douro Valley

What the classifiers highlight

Restored from a 19th-century manor above the Douro River, this hotel spreads 71 rooms with river-view terraces and freestanding villas with private pools through the gardens. MICHELIN calls it the clear top choice for the valley, citing the spa's grape-based treatments and Vale de Abraão, where a wood-fired open kitchen runs a farm-to-table tasting menu.
