Salt mining in the Aveiro region dates back to a time before the Ria de Aveiro itself existed, with the first written document about Aveiro salt production dating back to before the founding of the nation. Over the centuries, the instability of the inlet (isolation from the sea) was a decisive factor in the variation in the number and production of salt pans. This resulted in periods of decline interspersed with periods of great favorability for production. This occurred in 1572, when, given the favorable condition of the inlet and the high and progressive commercial and maritime index, Aveiro became one of the best ports in Portugal, with a significant increase in salt trade and cod fishing. In 1808, the new inlet (an artificial system that allows seawater to enter) was finally opened, a fact of exceptional importance for the future of Aveiro and the entire region.

Super fine sand, very spacious beach, little going on. There are many jetties in the dunes, so you can easily reach the beach.
