Praiasdaria Reviews 

This was an excellent tour along the old salt marshes of Aveiro.
Gustavo, the tour leader, is friendly, very knowledgeable and approachable, guiding the group through the many canals and explaining the history of the region and how the salt industry evolved over the centuries.
The tour might seem expensive at first, but it's great value for money, as it's long and detailed, with Gustavo happy to stop at any place along the route to answer questions.
Highly recommend

Very nice boattour na Ria d'aveiro. Gustavo knows a lot and gives you interesting information about the beautiful surroundings of Aveiro. We saw al lot of birds.
Skip the canal boattour and book this one! Totally worth it!
