Key Dive Site Facts
Dive Site Overview
A compact barge, now resting in two sections beside Sesimbra's harbor breakwater, forms the core of this engaging wreck dive. Descending to approximately 11 m / 36 ft, divers encounter the main wreck sections, while surrounding breakwater and tetrapod features extend the active dive area, starting as shallow as 2 m / 7 ft and reaching depths of 15 m / 49 ft.
