Paiva river walkway (Espiunca) is around 37 km away but worth a visit. The pedestrian route is linear, 9km long (one way) and some parts are quite steep. I think that the best place to start is Espiunca. Take into account that you need to buy a ticket and during summer time there's lot of people visiting so probably it's better to reserve it.
