Scuba Diving and Snorkeling at Playa Manzanillo

Playa Manzanillo lies in a series of rocky coves south of Zihuatanejo Bay, in the Zihuatanejo de Azueta municipality of Guerrero, reached by a short boat ride from the town pier out to volcanic-rock reef formations with swim-throughs and coral patches. Snorkeling from the surface requires no certification or prior experience and suits swimmers of most ages and abilities, while the shallow scuba diving here suits both open-water certified divers and complete beginners taking an introductory dive under direct instructor supervision; dive shops typically set a minimum age of around 10 for introductory dives. Mask, fins, and snorkel are provided for snorkel trips, and full scuba gear including tank, regulator, and buoyancy vest is provided for dive trips; divers bring or rent a wetsuit or rash guard depending on water temperature, along with a dive certification card if diving independently rather than on an introductory dive. Dive shops operating out of the Zihuatanejo bay pier are generally PADI or SSI affiliated, staffed by certified divemasters and instructors who lead every dive and brief the site's currents and depth before entering the water. A pre-dive safety briefing covers hand signals, equalization, buddy checks, and the plan for an ascent or return to the boat if a diver has trouble, and instructors stay close to introductory divers throughout the dive; snorkel guides likewise brief swimmers on entry and exit points around the rocky coves. Visibility and calm conditions are best from November to May, when the bay sees less runoff and gentler swell, making it the preferred season for both snorkeling and diving; the rainy season from June to October can reduce visibility and stir up surge around the rocks, so trips are more weather-dependent in those months.
