The Arnóia River rises in the Serra de Todo Mundo, and after receiving the waters of the Real River flows into the Óbidos Lagoon for a total of about 30 kilometers. Along its banks everything has come together to make them beautiful, fresh and peaceful.
From the dam that serves the agricultural fields, through lush greenery to the open views of the charming village of Óbidos, this is a beautiful and demanding trail. Those who like nature in its purest state cannot fail to do so.
