A total lack of pollution combined with a twisting route and a series of white water rapids make the Paiva ideal for rafting. Fantastic landscapes culminate in a choke point in the river, just a few feet wide, opening up in to a waterfall.

And for the less adventurous, the Paiva is also known for its fauna, including otters and many species of bird.

The stretch of river most highly recommended by the specialists covers over 17 kilometres between the bridges at Espiunca and Travanca. Take care though, descending the Paiva in winter and spring is best carried out by experienced rafters, given the high level of difficulty.

And while in the region, don’t miss the opportunity to spend some time on the other local rivers, the Arda, Sardoura and Douro. Indeed, the entire Douro region is worthy of close inspection with its port and wine estates.

It’s a short journey from the green of the mountains down to the bustle of the city. Porto is close by and provides all kinds of sightseeing and entertainment opportunities by both day and night.
