Very beautiful, but be careful: paths can flood at high tide. You'll then have to stand in knee-deep water for a few meters with your bike.

This place is called Ponte Caída because, as the name suggests, the old bridge collapsed. Today, a new structure stands very close by. This is where the Aveiro walkways end, offering a serene view over the Vouga River. From the top of the small dike, you can enjoy the tranquil beauty of the waters.

Most of the route runs on wooden footbridges. Everything is flat and easy to walk. Beautiful landscape of the Aveiro estuary. There are tons of birds to see.
