The Jornadas da Baía have taken place annually since 1999, and make up a set of pedagogical, sports, animation and sociability activities set against the Seixal Bay, revealing the unmatched beauty and potentiality of this natural resource for the promotion of health and healthy lifestyles.

The balance of this initiative has been very positive, involving many citizens, Project partner institutions and also young people from other Municipalities of the Portuguese Healthy Cities Network.

The 2nd Jornadas da Baía were held on April 7th 2000, and were aimed at the population of Seixal. Animation and sociability activities were developed, such as interactive performance at the commuting train stations of Fertagus and boat stations of Transtejo, during "rush hour". People were also given informative leaflets about "Health and the Bay", containing information on the goals of this initiative and the potentialities of the Bay for the promotion of health.

Some of the material held out was produced in co-operation with the Municipality School Establishments, especially the elementary schools.

There were also sport activities, especially canoeing, under the motto "Come and Try Canoeing at the Bay". These activities were aimed especially at the Educational Community, since an effort was made to give the elementary school children the opportunity to practice this sport, with the support and under the supervision of the Municipality’s nautical associations. Around 300 children from 30 Municipality school establishments took part in this initiative.

The first edition of the Jornadas da Baía aimed at celebrating World Environment Day and was held on June 2nd, 4th, and 5th 1999. On June 2nd a meeting was held at the Seixal Cultural Forum, under the theme "A Baía do Seixal, as suas Potencialidades e Fragilidades" (The Seixal Bay, its Potentiality and Fragilities). This meeting covered key agents for the Bay development, such as environment associations, businessmen, tourism and hotel business, school establishments, governmental institutions, trying to develop ideas for the healthy enjoyment of the Bay area, through the question:

How would you like the Bay to be?
On July 4th there was a walk along the Bay surrounding areas with some of the participants at the Meeting, and on the 5th there was a Cycle-Paper along the Bay, a nautical exhibition and guided tours along some tracks to discover spots which are considered natural, cultural and historical patrimony.
