Natoursabor is a nature and adventure tourism operator based in Trás-os-Montes, in northern Portugal, focused on activities around the Sabor river lakes (Lagos do Sabor). Its main offerings are guided boat tours — including a sunset boat trip and a themed tour to the Medal river gorge — plus kayaking, stand-up paddleboarding, hiking routes (such as a panoramic route and a Knights Templar-themed route) and private multi-activity tours combining boat rides with visits to nearby castles. The company lists diving (mergulho) as one of its activity categories, but no working page or bookable diving product could be found on its site at the time of this review; its confirmed, bookable activities are boat tours, kayak, SUP and hiking.
