Partida is a little rock out in the middle of nowhere. Part
of the Revillagigedo Islands, it lies about 70 miles west of Socorro
and 85 miles from San Benedicto Island. The tiny pinnacle jets up
from hundreds of feet of water. Topside the two points make a comfortable
home to the
and gulls who have made
their way here. Underwater it is a magnet to giant manta rays, whale
sharks, schools of hammerheads, dolphins, white tips, Galapagos sharks,
humpback whales, large schools of jacks and tuna, and of course,
When the Solmar V visits Roca, the dives are done from the pangas.
The view of the rock is stunning, but the smell of guano
usually helps get the divers quickly into the water. The visibility
is usually very good and the rock is an impressive site above and
under the surface.
The pinnacle is small enough that its possible to swim around it
several times during one dive. Other
times the current and surge can be strong making this more difficult.
Its not a difficult dive, but like in open water, divers must
always be aware of their depth and bottom time.
At about 30' there are several small caves
on one side of the rock where whitetip sharks are usually sleep
until disturbed by the underwater
photographers. Its common to see large lobster here too. As
the waves breaking over the rocks at the surface creates some interesting
Move further away from the rocks its not
unusual to see schools of hammerhead sharks anywhere between 130'
and 50'. There
have been incidents where the sharks come very close to the divers
to check them out.
Giant Pacific Mantas also congregate here and the encounter for
divers and underwater photographers can be a life-changing experience.
The mantas seem to be attracted to some divers and have been known
to play with them by swirling around them and swimming directly toward
them and over thier heads. Some believe the mantas identify you
by looking into your eyes and remember you when you come back. Of
course this makes for some fantastic photo opportunities. Mantas
have been known to follow the divers all the way back to their panga and staying until the boat pulls away.
Whale sharks have also been spotted at Roca as well as humpback
whales who stop here on their migration to and from Alaska.
For divers, Roca Partida is a world-class dive and is often compared
to Darwin and Wolfe Islands in the Galapagos.
