Socorro Itinerary Overview

Socorro Island is part of the Revillagigedos, a group of small islands off the coast of Baja California, Mexico. Dive sites include Socorro, San Benedicto & Roca Partida but may change due to ocean conditions. The manta behavior here is unique in the world. The 12-to-16-foot giant mantas of Socorro seek out intimate interactions with divers. They communicate with us, from locking eyes in a first contact to gently swimming just overhead to be tickled by bubbles. Sometimes they hover alongside or underneath a diver, where they often stay, curious and seemingly in want of a connection that has left more than one diver with tears of joy.

It’s one of the reasons we stay committed to the Socorro Islands (a.k.a. the Revillagigedo Archipelago), well worth the full-day motor south from Cabo San Lucas. Volcanic in origin, these islands serve as an oasis amid the Sea of Cortez, 250 miles off the Baja Peninsula coast. The raw lava flows and active volcanoes in these islands resemble the lost world of “Jurassic Park,” which seems fitting as these outpost islands, including 

Roca Partida, beckon not just to giant mantas but to a host of big animals.

Your journey will include four dives per day (subject to weather and unforeseeable circumstances)—each an opportunity to encounter resident pods of playful dolphins. You may also see up to 10 varieties of shark: schooling scalloped hammerheads, solitary giant hammerheads, Galápagos, whitetip reef, silver-tip, silky, tiger and oceanic whitetips. The list also includes whale sharks and dusky sharks and on occasion even a thresher shark.

On most days, we enjoy visibility of 70 to 100 feet. When the current picks up, the ash from these volcanic isles can rise, reducing the visibility to 30 feet. For the wide-angle experience that is big-animal diving, this isn’t ideal. But, we’re still cruising one of the most pristine underwater environments—so we then choose dives where we’re closer to the reefs and marine life such as eels, octopuses and Socorro lobsters.

Guadalupe Itinerary Overview

Guadalupe Island is a volcanic island 150 miles off the west coast of Baja California and outperforms every other great white shark destination with shark-seeing consistency and beautiful diving conditions.

Great white shark encounters at Guadalupe Island are nothing short of spectacular. Guadalupe feels like a remote outpost at the end of the earth but is actually incredibly easy to get to. Our trips meet in San Diego, California with coach transfers to Ensenada, Mexico. It’s the best destination in the world for calm, clear water and a consistently high probability of multiple shark encounters per day.

The sheer number of animals in the bay we dive is jaw-droppingly amazing. We see great whites on three out of four dives. The bay itself is home to 228 recognized individuals ranging from 12 to 19 feet long! At times, we have seen as many as nine sharks on one dive—and that’s because Guadalupe is just the sort of place where magic regularly happens in the water.

All certified divers will have the opportunity for a minimum of three dives per day in the submersible cages—and your trip includes the opportunity for unlimited time in the surface cages. Divemasters are in the water during every submersible-cage dive to ensure your safety. Note that the surface cages open at 6:30 a.m., and diving in the submersible cages begins at 8 a.m. Both are available until dusk.

I went on the Nautilus Explorer for a trip to Guadalupe Island to photograph Great White Sharks. This had been on my bucket list for awhile, and it exceeded my expectations. Despite the long crossing from Ensenada to Guadalupe Island, the trip was well worth it. Seeing the sharks up close and personal was incredible. We had multiple sharks around the cages at all times, which made for great photography. We also had a few visits from seals (including one adventurous seal who chased and nipped at the sharks) and one encounter with a massive school of yellowfin tuna. However, the main attraction at Guadalupe Island is great white sharks. If you are expecting a diversity of wildlife at Guadalupe Island, I would probably suggest going elsewhere. However, if you want to view great whites in good visibility (visibility was consistently 100 ft+), I'd highly recommend Guadalupe Island.

The Nautilus Explorer was the perfect vessel for this trip. The staff is incredibly friendly, the food is great, the rooms are big (especially the master suite, but all rooms were quite nice for a liveaboard), the hot tub is WONDERFUL and the diving is incredibly easy. There are 4 cages on the Nautilus Explorer: two deep cages (40 feet deep), one medium cage (18 feet) and one surface cage. The two shallow cages are always open for divers (first come, first serve), and the two deep cages have schedules that allow for equal viewing among all divers. Shifts in the deep cages are 40 minutes and the time absolutely flies by.

The other nice thing about diving Guadalupe Island on the Nautilus Explorer is that you don't need your Scuba gear. Air is provided from the surface, so you just need a wetsuit and mask.

I would love to go back on the Nautilus Explorer for any of their trips, whether it is back to Guadalupe, the Sea of Cortez, or the Socorro Islands. And for those looking to see or photograph Great Whites, a trip to Guadalupe is a must, especially for those living in the United States. It's way easier to get to San Diego/Ensenada than Australia or South Africa.

I went to Guadalupe on the Nautilus Explorer in September 2015. Overall, it was excellent.

Food: We had all types of food allergies on our trip (gluten, dairy, eggs, etc.) and everyone was well accommodated, and the chef paid very close attention to cross contamination. The food consisted of a continental breakfast, full cooked breakfast, lunch, dinner, and snacks. Everything was delicious and there was plenty available. It was some of the best food I've had on a liveaboard.

Cabins: I like the fact that the double cabins are side by side beds, not bunks. There's plenty of storage space. By comparison to most other liveaboards, the cabin are a decent size. The shower always had hot water and strong water pressure. The toilet was a real toilet (like you'd find in your house), not a marine toilet. The only complaint I have about the cabins (and why I gave it 4 stars instead of 5) is because the mattresses are really hard. However, I was told that you can ask them to put a comforter between the fitted sheet and the mattress, which would help.

Crew: Stellar. Every one of them. The hostesses are always around to bring you a drink, snack, or whatever you need. The crew will bend over backwards to ensure you have an amazing trip.

Diving: Great white sharks - what's not to love?!? Nautilus Explorer runs an on-time and efficient dive schedule for the submersible cages. The guys on deck are always available to help you don weights or get in/out of the surface cages.

Overall, I was very impressed with this boat and I'm already scheduled to go on Nautilus Explorer again next year.

I was fortunate enough to be in Guadalupe Island in 2018 on the Nautilus Explorer. We sailed in the end of July and it was a trip of a lifetime! Guadalupe is a little difficult to get to - it's a 3 hour bus ride from San Diego to board the ship in Ensenada, Mexico, followed by a 20 hour sail to reach the island. The crossing can be rough when winds/waves are up...but when you arrive it's all worth it! You are anchored in the leeward side of the island so the ocean was as smooth as a swimming pool the whole time. You could actually see the sharks pretty well from the deck!

We had sharks there all 3 days, all day long every day. There seem to be more sharks there than in the past? According to the crew, the seal populations have increased over time and have allowed the sharks to do the same. The sequence on day one starts with alternating 1 hour in a cage and 1 hour out so that everyone gets equal time in the cages. However, starting on day 2, the cages were not always full - so you could stay longer if you wanted. The water in late July was as warm as it gets - mid 70's F - so you need a thick suit/dry suit to maximize time in the water.

As for the ship, the food was good and the staff was great! Very energetic bunch and they took care to make sure we were well taken care of. Would highly recommend it!

Bottom line - if you have always wanted to see Great Whites, this is the BEST place in the world to do so. The visibility is as good as it gets there (80 - 100 feet?). Keep in mind that in cage diving you have only a wetsuit and weights - no BC or tanks - so you can expect to wear 30 - 40 lbs of weight just to be able to submerge. Also realize that there is nothing else to see in the water when the sharks are not around, so there may not be something to see all the time. Even so, one of my best memories of the trip is sitting in the cage by myself at the beginning...waiting...and then having a massive shark shoot up at the bait right in front of me! Hope to visit again someday...

I bought my Mum a trip on Nautilus’ liveaboard for her birthday, as soon we showed up in Mexico they helped us through every stage. They offered a free checkout dive package for us right there before we got on the boat, it was a great way to knock the dust off since it had been a few months. The trip itself was awesome, sea lions, manta rays, and so many fish! We even got a surprise with two schools of hammerheads! The best part was how relaxing the crew made the trip, my mum describes the week as “truly magical” and it really was great.

I took the Nautilus Explorer to Socorro in November 2021. The crew was very good; however, I was not as impressed with the dive masters. They seemed to push the envelope and had us swimming against the current a lot. One dive master swam off and left half the group on one dive! A couple of the guest were very upset with the dive masters! The boat was very comfortable! The food was good. I stayed in one of the cabins for a single occupant. I found it to be wonderful! The bed was the BEST bed I have ever slept in on a liveaboard! I especially liked the night snorkel with the Silky Sharks! That was a lot of fun. One of the crew stood on the stern with a loudspeaker yelling when the sharks would come toward the back of the boat where the snorkelers were. It was a festive atmosphere! Despite not being impressed with the dive masters, I would go back on the Nautilus Explorer again! Sorry, but my photos are too large to download.
