Roca Honda - Isla de la Plata is a boat-dive pinnacle off Puerto López where the draw is the structure itself: a compact rocky rise with wall relief, cleaning-station action, and busy Pacific fish life. The site suits certified divers who are comfortable in open water and keeping a tight route when current builds. Plan it as a guided day trip from Machalilla National Park, with seasonal manta and whale visits adding to the appeal.
