Quinta do Ventozelo
Set above a picturesque bend in the Douro River, the Quinta do Ventozelo has rooms in lovely adapted agricultural buildings, including two balões—concrete vats once used to store wine; it also hosts winery visits and tastings of wines from the Gran Cruz company. For a special stay, there's the secluded Casa Romântica, while groups can book the riverside Casa do Rio, or the sprawling Casa Grande, with its private pool. The Cantina restaurant and wine bar, whose terrace affords a panoramic view of the valley, serves traditional fare and vegetarian options. The estate even has a small museum, telling its story and that of the region.
