Naturisnor is a nature-tourism company in northeastern Portugal, offering stays and outdoor experiences in the Douro International Natural Park. Its accommodation, Casa das Arribas, is located in the village of Cardal do Douro, in a building based on a former primary school. Set on the slopes above the Douro River, the house overlooks the Bemposta reservoir and provides a base for exploring the region.

A highlight of Naturisnor’s activities is a 2.5-hour boat trip aboard Arribas do Douro, designed to reveal the natural scenery and hidden features of the river gorge. Visitors can also explore viewpoints on guided 4x4 and walking excursions, enjoy snacks in the hills or meals beside the river and aboard the boat, and try stand-up paddleboarding and kayaking through local partner companies. Wine tastings and vineyard visits offer another way to discover the area.

Naturisnor presents its experiences as authentic ways to connect with the landscapes and local character of the Douro. The company also lists Biosphere Committed recognition and responsible-tourism policies.
