The Nautical Station of Sant Carles de la Ràpita celebrates in June the `Fiesta del Mar´, with a wide range of activities related to nature tourism and water sports. The most outstanding act is the Alfacs Bay, with a mussel lunch in the `Xiringuito de la Costa´ kiosk. There is the chance of renting electric bikes to make routes through the Delta, tastings and many more activities with the aim of bringing people of the Tierras del Ebro closer to the enormous possibilities offered by the Alfacs Bay throughout the year.
