Brannec is a boat-access wall dive in the Gulf of Morbihan, starting from a sandy bottom and moving onto a vertical rock face with layered strata. From the boat, the route follows the left-hand edge before the wall opens into a measured, terrain-focused descent. The site rewards slow exploration of the rock bands, sponges, and temperate marine life tucked into the crevices.
