Casa do Río Wine Hotel, Douro Valley

Located less than an hour from the border of Spain, Casa do Río Wine Hotel offers a peaceful and remote stay deep in the Douro Valley. The hotel is run by descendants of Dona Antónia Adelaide Ferreira or "Ferreirinha," one of the region's most influential wine producers in the 1800s. It's situated just 10 minutes from Vila Nova de Foz Côa, where you'll find a handful of markets and restaurants and the archaeological park containing Paleolithic rock engravings dating back 25,000 years. Porto is a 2.5-hour drive, making this ideal for those who want to experience Portugal away from the crowds.

The hotel is built across a gorge and blends into the landscape. There are just under 10 rooms and suites, which are modern, cozy, and bright, with floor-to-ceiling windows and balconies overlooking the river and rolling hills of the valley. Each room has a fireplace, a great addition in the winter, and a contemporary style of earthy tones and minimalist furniture adds to the space's warmth. Suites include small private pools and bathtubs for extra relaxation. This adults-only hotel is open to guests 12 and above, so it's best for couples or friends looking for a quiet oasis getaway.

Hop on one of the bicycles the hotel provides or take a spin in the property's boat, kayaks, or paddle boats. This part of the Douro Valley is known as terra quente or "hot land" because of its scorching temperatures in the summer, so take a dip in the infinity pool overlooking the river to cool off during the high season. The restaurant offers simple fare for lunch and goes all out for dinner, where you can sample some of the region's best dishes. Of course, you can try some wine too, and if that's what you're here for, you can take part in one of the regular Quinto do Vallado wine tastings.
