Why dive here
With 195+ marine species recorded in the area - including blue whales, dolphins, humpback whales, nurse sharks and orcas - Roca Montana offers some of Sea of Cortez's richest diving. Water ranges 21-31°C, warmest August, September, October.
Roca Montana sits at a comfortable 14 meters, making it a good spot for newer divers looking to get their fins wet. The site is a shallow reef, home to a scattering of juvenile angelfish and the occasional pufferfish. It's a relaxed dive, usually with mild currents, and we often see divers practicing their buoyancy here. We’d recommend it for a gentle introduction to Sea of Cortez diving.
