The Troncalhada salt pans are located on one of the canals on Aveiro and Troncalhada is now an eco-museum.
At one time, the area had many salt pans, but today there are just a few. Salt pans are very important environmental sites . Many types of waterfowl live in the marshes and surrounding areas.
Informative moliceiro tours of the river, surrounding areas, and the salt pans start at the main canal in town. This is something you'll enjoy. The salt worker gives you a chance to collect some dried salt in a pail and add it to the main pyramid of glistening white salt. After the tour, you can buy different varieties of the natural sea salt. Try the Piri Piri (enhanced with hot piri piri peppers) which is a favorite of the Portuguese. You can also walk or drive to the site and purchase the salt.
The salt is also for sale at a kiosk on the main canal. The price is much lower this way than in the supermarket.
I was fascinated with the salt pyramids when I was in Aveiro. This fascination goes back to my childhood when I saw pictures of these hills of white.
Finally, I was there and I was filled with awe just watching the process. The work is not easy with the hot, Portuguese sun beating down from the clear, azure sky, especial in the Summer months. The workers even have a hut for a break and for shelter from the sun and heat.
I enjoyed every minute of this experience.
The tour or your own ramblings of this area is something that should be on your itinerary for Aveiro.
