Quiet Scuba Diving Day at Roca Partida

We consider Roca Partida to be the crown jewel of diving Socorro/Revillaigedos but by the very nature of Big Animal diving, it’s not always going to be super hot. Current scientific thinking is that the local population of giant manta rays actually traverse a 1200 km route that takes them by San Benedicto Island, Socorro Island, Roca Partida and then up and across to the west side of Baja California before looping south again.

Giant Manta Interaction with Divers at Socorro/Revillagigedo Islands

So, over 200 identified Socorro mantas now with lots of resightings and many thanks to everybody who sent manta images and video in to Bob and Karey over the summer. Karey made one especially interesting comment to me that she was able to positively identify several animals a day or two apart at different islands from images taken by our guests. One wonders if the mantas preceded the Nautilus Explorer or followed us??

Giant manta ray migratory route

  • Post author By Nautilus Staff

Highlights included a huge bait ball of skipjacks being hunted by silky sharks and 100-pound yellowfin tuna, a group of five hammerhead sharks that approached within 40 feet of the divers and a blue water drift dive looking for pelagics. All the usual Roca Partida critters were present, including over 30 white tip reef sharks, silky and Galapagos sharks and some curious wahoo.

Flat calm crossing

Had a great run from Roca Partida straight back to Cabo San Lucas. Sometimes it is a rough crossing with 6 – 8ft seas. Most of the time it is pretty nice, with the ship gently pitching up and down and an easy roll from side to side. And sometimes it is flat calm. This crossing was so calm that it was as if we were already tied up to the dock!
