Comments This Argo trip was pretty fantastic compared to my July 2015 trip on the Aggressor. I think part of it was the time of year (early Oct. vs. mid July resulting in slightly cooler water), but a big part was the divemasters’ (DM’s) discipline about staging people in the cleaning stations, making it very clear that we were to get on the rocks and stay there because if anyone was swimming around the sharks wouldn’t come. We had very good success at the cleaning stations (and swimming in the blue).

By the end of the trip (20 dives) I estimate I saw over a thousand hammerheads, lots of Galapagos sharks, silver tips, a black tip, a tiger, a couple of minutes with a 20’ whale shark, a few eagle rays and mobula rays, some silkies, and huge huge huge schools of jacks that we swam into. When we’d swim into the blue it wasn’t uncommon to find schools of 50-100 hammerheads and at times they weren’t that far from us – sometimes as close as 20-30’.

The Argo crew is pretty amazing, with a special nod to Juan Manuel the cruise director/divemaster – I’ve never seen a crewmember who could make all the guests and his coworkers laugh so much. We dove with 4 different DMs, one or two on each dive, and sometimes we had a third with a big camera shooting pictures. There’s no trip video for sale but they make all the pictures they shot available on a computer for everyone to copy to a USB drive or memory card, and guests are encouraged to make their photos/videos available as well. The cabins were comfortable – no issues. The skiffs are fiberglass boats with sun canopies but you can still be exposed to the sun going out or coming back since you mostly sit in the same spot on the side of the skiff all the time.

Some odds-and-ends: they can do laundry for you as long as you get it to them before the last dive day; they have hair dryers but you have to ask for one; soap, shampoo, ear plugs were provided; they had boxes of Dramamine in the salon to combat seasickness for those who ran out or didn’t bring anything; since you have to fly in a day early you have to book a hotel and their shuttle picks up at 4 hotels – Hampton Inn Airport where I stayed, Park Inn, Grano de Oro, and Costa Rica Marriott San Jose. My pickup time for the shuttle to Puntarenas was the last pickup at 11am, and I was the first dropoff at 9:30am on the return (had no problem getting into my room e ...
