Boat launch and section choice make local operator guidance the normal setup.
El Negre Petit is a boat dive on the outer end of Mataro's Negre bar, where a wide rocky ridge alternates between porous rock, gorgonians, and pockets of typical coastal life. It rewards slow route-planning more than speed, because the bar lets divers adjust their profile while still needing sensible bottom-time control. The site is especially attractive for photographers when visibility is good and the light reaches the rock cleanly.
