Rocky offshore Sesimbra dive with cliffs and anthias.
Penedos is a boat dive just offshore from Sesimbra where large boulders and abrupt depth changes create a compact rocky landscape. Cliff faces and ledges rise through the site, with hard coral and dense anthias giving it a brighter, more life-filled feel than the surrounding sand and mud. It rewards controlled descents, close reef work, and comfort with current and changing visibility.
