Rocky Mataro boat dive with circus-like formations.
Rocky Mataro boat dive with circus-like formations.
A local Mataro dive center is the normal way to reach El Circus by boat.
El Circus is a boat-access rocky dive off Mataro where unusual stone formations create a circus-like landscape and make the site a good fit for creative underwater photography. The dive is more about moving slowly through rock shapes, cracks, and open sand than about coral gardens or long swim distances, and the main attraction is the combination of structure and classic Mediterranean fauna such as octopus, moray eels, conger eels, and schooling fish. It is best treated as a relaxed boat dive with winter conditions usually giving the calmest sea and clearest water.
