The creek where Illa Mateua is located it’s between Punta dels Cinc Sous (west) and Punta del Romaní (east). The Punta del Romaní is commonly known as La Depuradora and it is a diving point that can be reached by the beach without many difficulties. Once in the water it is easy because we can follow the wall in our right hand and, at the beggining, there is a tunnel at -6 m very colorfull and there is a great amount of coralligen and some congers. 

Leaving the tunnel behind we can proceed in two different ways. The first option is to keep following the wall because we will find some other tunnels that are really interesting; the second option is to dive through the blue and we will fins a pinnacle from -12 m to 17 m. If we are lucky we can finde some seahorses and, for sure, a huge amount of nudibranchi biodiversity.
