Óbidos Lagoon, located in the Caldas da Rainha and Óbidos regions of Portugal's stunning West Coast, is a natural treasure waiting to be explored. This shallow lagoon, with its irregular and ever-changing contours, is separated from the sea by a barrier of coastal dunes. Its connection to the ocean is through a variable-width channel known locally as the "aberta." At times, this transition point closes, necessitating interventions to maintain an open passage.
