Scuba Diving in Roca Partida

Roca Partida mean Broken Rock in Spanish. This stark volcanic pinnacle rises from the depths of the Pacific 200 miles (320 km) off the tip of the Baja Peninsula. This is truly wild diving, with powerful swells, big currents, and large marine species at one of the most isolated dive sites in the world.


The most remote outcrop of the Archipelago of Revillagigedo (a group of four islands), Roca Partida rises starkly from the wild surface of the Pacific Ocean, its rugged silhouette reflecting the characteristics of the reefs beneath. Steep walls plunge into deep, dark water, with very little life encrusted on their barren surfaces.

The rock is gorgeous and I’m sure you’d be happy to watch it as longer as you can , however the smell of guano usually force you to make your immersion as soon as possible. Roca Partida is not big and its achievable to swim around it several times (the current and surge) during one dive.

Large lobster can be seen quite often in this place. Going further away from the Roca Partida hammerhead sharks can be spotted in large numbers. hammerheadIncidents where the hammerhead sharks approach very close to divers have been recording in past. The rich upwellings from deep water around Roca Partida provide plentiful nutrients and oxygen for circling fish shoals, including huge black jacks and dense schools of barracuda. These in turn attract silky, white-tip, silver-tip, and hammerhead sharks in great numbers. What makes this dive site so special, however, are the manta ray encounters, which are among the best to be had anywhere; these magnificent animals almost seem to seek out divers, resulting in some extraordinary interactions. It’s very likely that divers will meet this amazing creatures. It seems that they can be attracted by some divers,  sometimes they are even playing with divers , swirling around  and swimming directly toward them . Some people believe that mantas can identify you by looking into your eyes and will remember you when you’ll be back. Diving center SolmarV  video in which Manta Rays are playing with divers.
