Comments From July 9 through July 18, 2021, I had the pleasure of diving in Malpelo. I dived on a half boat charter with Sten Johansson, aboard Colombia Dive Adventures’ Ferox. This was my first international trip since going to Bonaire in Oct-Nov 2019.


As I was going on a half boat charter with Sten Johansson, reservations were handled by his very capable wife, Tanya. She did all communication with Colombia Dive Adventures. This trip was originally scheduled for June 19-28, 2020, Covid did that in. The trip was rescheduled and Colombia Dive Adventures deferred final payment until this year. This year’s trip was nearly also lost due to protests/demonstrations in Colombia. The trip just prior to ours was cancelled. Fortunately, the political situation stabilized and we were able to go. Throughout this entire period, Tanya Johansson communicated frequently and clearly, I always knew where I stood.

I made my own reservations to fly on American Airlines from Philadelphia to Miami to Cali. The 2020 flights were cancelled by American Airlines and refunded. I made my reservations for two nights at the InterContinental Hotel in Cali online. There was no problem cancelling my 2020 reservations. I traveled from the airport to the hotel and back in a private car with another diver from the US. This was easily arranged through the InterContinental Hotel concierge.


Despite the complexity leading up to this trip, all of the travel went perfectly smoothly. Colombia dropped the entry Covid PCR test just a few weeks before my visit. One did have to fill out an online immigration form shortly before arriving and an emigration form shortly before departure. The immigration form was required for check in at the Philadelphia airport and the emigration form was checked at emigration in Cali. Travelers without the forms were required to exit the line and fill out the forms on their phones. A negative Covid antigen test was required for reentry into the US. Testing was arranged by Colombia Dive Adventures and was performed in Cali when the bus stopped at the testing center on the way back to the InterContinental Hotel. Cost was $45 and the result was in my email shortly after arriving at the hotel. One was required to sign an affidavit and show the test result at check in in Cali.

All four of my American Airlines flights were on time and included my luggage. AA has an app that allows for tracking your bags. It was always nice to know my luggage was on the plane with me. The private car from the airport and back worked perfectly. The InterContinental Hotel was more than adequate. Breakfast is included and was served from a generous buffet from behind a glass partition. A server simply loaded your plate(s) with the items you wanted and hands it to you at the end. The hotel has 5 restaurants on site, the two I tried were good, and relatively inexpensive. Transportation by bus to and from Buenaventura is supplied by Colombia Dive Adventures, as part of the package and takes 3-4 hours, partly dependent on the length of the rest stop. The travel distance between Buenaventura and Malpelo is a little over 300 miles/490 km and takes 30-36 hours. The trip on the way out was moderately rough. Sea sickness prophylaxis is advised for those susceptible to it. The trip back was not quite as rough, but wouldn’t be described as smooth sailing. Sleeping was not easy when being rolled back and forth in bed.

Boat and Crew

The Ferox is not a luxury liveaboard, but a safe, comfortable place to live while diving in Malpelo. The Ferox is named after the species name of the Smalltooth Sand Tiger Shark. It is found in cold water, usually deep, especially at the site, Bajo del Monstruo. Ferox is a former Swedish Navy, ice class, mine layer with, an 11 mm steel hull. The boat has dual generators and a waste water treatment plant. The main deck includes the kitchen and the dining area. There is a modest sized camera table with compressed air. The upper deck has the lounge and sundeck. The Ferox takes just 12 divers, two groups of six. Cabins include two queen bed rooms for double occupancy, 2 single full bed rooms, 2 single bed rooms on the main deck, and 4 single bed rooms on the lower deck. The two single rooms on the main deck and two other rooms nearby are just steps from the open main deck. The six rooms on the lower deck have an emergency exit to the main deck on the bow, in addition to the main route. All rooms have ensuite bathrooms including showers and separate air conditioner controls. I found the split level A/C to work very well. I took all my showers on the main deck at one of three showers with more than ample hot water. I had one of the main deck single rooms and found it very comfortable. I saw one of the lower deck single rooms, it was slightly larger than mine but extremely similar. The cabins are also all steel, limiting the amount of flammable material. All rooms have a hard wired smoke detector, a battery operated back up smoke detector, and emergency lighting.

All diving is done from the two rigid inflatable boats. These were the most rugged RIBs I have dived from. They were former fast rescue boats from the North Sea. Each has twin 60 HP Yamaha outboards, a sturdy dive ladder GPS, an automatic identification system (AIS) for tracking the diver personal locator beacons (PLBs), and VHF radio. Each diver is given a PLB and all are instructed in its use. Cylinders, BC, and fins stayed on the RIB. The cylinders were filled in place. The Ferox has a primary compressor and nitrox generator, a backup compressor, and a 14 cylinder cascade system. Tank fills were quick and reliable. I dived an AL80, my average 32% nitrox fills were 3084 psi (2990-3212 psi). They also had AL100 cylinders available, many dived them. The AL100s were filled to the same pressure as my 80s. The two RIBs go to different dive sites. Entries are back roll with a negative descent. Cameras, weights, cylinder and BC, and fins are passed up before boarding.

There were 11 crew members, including the two guides, Sten Johansson and the very experienced Jaime. The owner of Colombia Dive Adventures and the Ferox. Tony, was on board for our trip. He accompanies nearly all trips. He was in the merchant marine for many years, much of it supporting saturation divers. He was living in Colombia when he decided to start the business, identify the proper boat, etc. The rest is history. It was fascinating discussing the birth of Colombia Dive Adventures with him. We had a dedicated RIB driver for the week, Rudolfo, he was very good. The cook had an assistant, who also took care of our rooms. The crew was very hardworking and helped each other out in activities. This was the first trip for a very long time, it went incredibly smoothly, under the direction of Tony. The entire crew had meetings each afternoon to discuss how things were going.

Each diving day stared early with fruit, breads and coffee. Full breakfast followed dive #1 and was served to order, eggs, pancakes…brought to the table. Lunch was served after dive #2, plated, brought to the table. Dinner was served after dive #3, also plated and brought to the table. I do not eat meat, chicken or fish made up the main course for all my meals. The food was generally good to very good, often Colombian cuisine. If you’re looking for the gourmet food served on luxury liveaboards, you are in the wrong place Alcohol is said to be extra, it was free flowing and free on our trip, Colombian beer and Chilean wines.


When I think of the diving on Malpelo, the one word that seems like the best descriptor, is wild. There are currents, sometimes strong, often changing during the dive. There is surge, sometimes strong. On one dive, I would take a kick or two to slow my backward movement, only to shoot forward at a very fast rate during the forward motion. There were significant thermoclines. Often, the surface and shallow temperatures would be 80-81 degrees and would drop abruptly to 72-73 at depth. I dived in a full 5 mm full suit with a 5/3 mm hooded vest. This was the best choice for me, as I was only slightly warm occasionally, and just a bit on the cool side when the temperatures were at their lowest. I wore light, but rugged gloves on most all of the dives, highly recommended for holding on in the current and/or surge. The visibility could change from clear blue water to green water with 20 feet of visibility. The same sites varied very significantly from dive to dive, it was as if it were a completely different dive and I did not even recognize it. Seas varied from less than two feet to something like 3-5 feet. The RIBs handled the seas with ease. We had bright, sunny days and impressive squalls.

The maximum depth for all dives averaged 93 feet (65-116 feet). The mean average depth was 56 feet (42-75 feet). Average dive time was 59 minutes (43-69 min). The average low water temperature was 75 degrees F (72-81 degrees F). The shallower temperatures were often considerably warmer than at depth. The dives were not as aggressive as they might seem from the depth and time. I dive one computer running DSAT and one running a Buhlmann GF high of 95. My lowest NDL times were 8-9 minutes, half the dives had remaining NDLs of <15 minutes. My highest surfacing GF was only 68, and averaged 51. Surface intervals between dives 1 and 2 and between dives 2 and 3 each day averaged 2:32 (1:57-3:20)

Sten Johansson turned out to be the ideal guide for Malpelo. Not only does he have 10 years of experience diving Malpelo, but he has an uncanny ability to read the conditions at the sites, to plan and execute a perfect dive. He is a wealth of information regarding Malpelo and is happy to share other interesting stories, he has more than most of us! I was very happy that Tanya Johansson was able to join us for this trip. I was able to thank her personally for her help in arranging this trip and enjoyed diving and chatting with her. Sten and Tanya are kind, considerate, nice people, I’m glad to be able to call them friends. Both Tanya and Tony celebrated a birthday during the trip, it was very nice.

The dives varied from good or very good to absolutely amazing. We did not see the huge schools of Scalloped Hammerheads that Malpelo is famous for. We did see numerous individuals and small groups, particularly on the second half of the trip. Most of the hammerheads were relatively far off, some were closer. What we did see was a very large number of Galapagos Sharks. On one dive on La Nevera, they were swooping toward us from every direction. We often had huge schools of fish around us, Bigeye Jacks, also known as Bigeye Trevally, Mullet Snapper, Leather Bass, Bluefin Trevally, Whipper Snappers, Almaco Jacks, and Cubera Snapper. There were often an uncountable number of Speckled Morays below us, many free swimming. At Bajo del Monstruo, we were dropped on a Whale Shark and another came cruising by later in the dive. We saw several other Whale Sharks during the trip. The dive at Terreferia was particularly crazy, with Almaco Jacks and Cubera Snapper all around, while we clutched the reef in the high surge. The usual reef fish were present on every dive, Barberfish, Guineafowl Puffers, King Angels, Chinese Trumpetfish, Blue-spotted Coronetfish, scorpionfish, clouds of Cardinalfish, Giant Hawkfish, Mexican Hogfish, Moorish Idols, surgeonfish, triggerfish, filefish… The last day of the trip finished at Three Musketeers. The huge school of Mullet Snapper and Bigeye Jacks was so dense that we lost track of one another.

I have been to Cocos, Galapagos, and Revillagigedos. Malpelo does not have the most diversity, or even the most large animals. However, it is the most wild, surprising and unexpected. It is exactly my kind of diving.

Craig Having been to Malpelo, Cocos, Galapagos and Revillagigedos, which did you feel had the most diversity and large animals?
By report author: Craig A Wood in PA, US at Oct 30, 2021 18:41 EST  
Galapagos had the most diversity, all kinds of sharks, mantas, whale sharks, penguins, marine iguanas, sea lions, mola mola... The most big animals probably goes to to the Revillagigedos, many sharks, dolphins, and mantas, mantas, mantas. Cocos also had many big animals, hammerheads, Tiger sharks, many, many Whitetip Sharks, too bad the night dives are gone. As I said, Malpelo was the wildest, all kinds of stuff, big and small, and the most challenging conditions. In my view, the 4 areas are not to be directly compared, but are complimentary. I am very fortunate to have been able to do all three. Where will I go back to first, probably Revillagigedos. It is an easy trip to get to Cabo and I really liked my Nautilus boat. Malpelo keeps gnawing on me to get back before I am too old and infirm to do it :-)
