Conil de la Frontera has a municipal indoor swimming pool, located in the Municipal Sports Complex. Here you can practice free swimming or take swimming lessons for all ages.
To participate in competitions at regional and Andalusian level, it is necessary to register with the Conil Swimming Club, from the youngest to the Master category.
The town hall of Conil organises annually, together with the Conil Swimming Club, the Big and Small Tuna Trophy. This Trophy is held over a weekend, which includes swimming events of different styles for the youngest swimmers, from three years of age (in collaboration with schools and other clubs in the province); and events for master category without age limit, for the most veteran swimmers.
