Castelo de Paiva Portugal is a Portuguese village, part of the Tâmega e Sousa sub-region, belonging to the North Region and the District of Aveiro. On the left bank of the Douro River, the Paiva River flows, certainly one of the cleanest rivers in Portugal, following this river there is a place called Sector de Escalada do Ratão, Although it is a spot previously populated by climbers it is a great Highline spot, also you have many options for waterlining, there are plenty of trees at the bank of the river where you can easily get your waterline rigged.

When this article was written there was two middleline rigged each one around 15 meters high and 50/60 meters long both of them using natural anchor, between two trees, in addition, there is a boulder bolted where you can rig the highest line above the Rio Paiva instead, it is a 70 meters line, it is important to say that the opposite side of the boulder the set up has to use natural anchors.

Alongside this line, you also can set up a few lines, however, on the date, this article was written you needed to get the rocks bolted.
Besides that, you have a perfect amusement park for canoeing, swimming, camping, and whatever else you like.

The spot was improved by a group of climbers who like to spend the weekend in nature, you also can practice bouldering before going for a climbing sesh, and when you get on top of the rock just put your leash on and try some Highline, Actually, it doesn’t sound safe so forget it and go up of the rock walking by the trail and yeah you are ready for a Highline sesh.
