Morros de Potosí – Ixtapa-Zihuatanejo & Acapulco
Site Overview
Morros de Potosí is the premier dive site off Isla Ixtapa featuring dramatic rock pinnacles adorned with colourful gorgonian sea fans, schooling snapper, green sea turtles, and occasional whale shark visits during the winter months that make it one of the most rewarding dive destinations on the Guerrero Pacific coast. The volcanic rock formations create varied underwater topography with pinnacles and walls descending from the surface to 25 metres, covered in dense gorgonian sea fan colonies that extend their polyps into the gentle Pacific currents creating beautiful underwater gardens. Schools of snapper and other reef fish patrol the pinnacle formations in constant motion, providing dynamic wide-angle photography subjects against the colourful sea fan backdrops. Green sea turtles are regular visitors during the warmer months, gliding gracefully along the walls while feeding on algae and invertebrates growing on the rocky substrate. Moray eels occupy numerous crevices throughout the pinnacle formations with multiple species present including green morays and spotted morays. During the winter months from November through March, whale sharks occasionally pass through the nutrient-rich waters near Isla Ixtapa, providing exciting surface encounters for alert divers during transit between dive sites. The site's proximity to the Ixtapa hotel zone, just a 15-minute boat ride, makes it highly accessible for resort-based divers seeking quality diving without extensive travel logistics. The moderate depth profile and mild conditions accommodate divers of various experience levels, with beginners exploring the shallower pinnacle tops while intermediate divers work the deeper walls where the largest sea fans and most diverse marine life are found. Morros de Potosí represents the best of what the Ixtapa-Zihuatanejo region offers underwater, combining geological drama, biodiversity, and accessibility in a single dive site that consistently delivers rewarding experiences.
Dive Briefing
"Morros de Potosí is reached by a 15-minute boat ride from Ixtapa's marina. Descend along the pinnacle formations starting at 3 metres where the gorgonian sea fans begin. Work your way around the pinnacles observing the colourful sea fan gardens and schooling snapper that patrol the formations. Green sea turtles are commonly encountered along the wall edges — maintain a respectful distance and observe their feeding behaviour. Moray eels occupy crevices throughout the rocky substrate with multiple species visible on most dives. The guide will lead you through the best pinnacle sequences where sea fans are largest and marine life is most concentrated. Ascend gradually along the shallower pinnacle tops enjoying the abundant fish life and sea fan gardens in natural light. Surface intervals offer views of Isla Ixtapa's rocky coastline and potential whale shark spotting during the winter months. Multiple dives around different sections of the pinnacles offer varied perspectives and marine encounters."

Traveler Notes
Who is this for?
Excellent for intermediate divers seeking pinnacle diving with colourful sea fan gardens and diverse marine life in mild conditions. Open Water certified divers can enjoy the shallower formations while Intermediate divers explore the deeper walls. Great for wide-angle photographers capturing sea fan gardens with schooling fish and macro photographers finding diverse invertebrate subjects. Snorkelers can participate in the shallower areas with good fish visibility from the surface. Not ideal for divers seeking extreme depth or guaranteed large pelagic encounters as whale shark sightings are seasonal bonuses rather than primary attractions.
