Submarine Excursions: What to Expect with this Unique Cruise Experience

Cruisers may hesitate to partake in a submarine excursion after the tragic implosion of the Titanic submarine in 2023. Although that was a completely different situation, tourists may wonder if a submarine or submersibles are safe. According to experts, yes they are. Here’s what you can expect if you brave a submarine excursion, or something similar, popular at port destinations such as Barbados, Cozumel, Aruba, and Bonaire. Most of the cruise lines will offer these as excursions, or you can book independently.

Submarine Excursions

First, get the details of your submarine excursion and read reviews before booking, as it may be a “semi-submersive” experience. My experience was the real deal — a fully submerged submarine adventure at Oranjestad, the Aruba Atlantis Submarine Expedition. This was a great experience, but a little pricey, so now that I’ve done it once, I don’t really have a desire to do it again any time soon. If you’re claustrophobic, you’ll want to skip this one.

On my excursion, our group met right outside the cruise port, where we were put on a water taxi and transported over to the sub. This transport took about 20 minutes each way, and then we spent approximately 90 minutes in the sub, which, for me, was more than enough time.

What to Bring to a Submarine Excursion

Participants don’t get wet with a submarine excursion, so you don’t need to wear or bring anything special. You’ll end up in a very cramped and confined space, as they cram tourists in, like, well — sardines in a can, so wear comfortable clothing. Getting down into the sub and back out will likely involve climbing a vertical ladder, so some degree of mobility is required, although that’s really the only physical aspect of this excursion.

On my submarine adventure, our captain took us 130 feet under the surface and navigated around a couple of shipwrecks and reefs. It was really cool to float along peacefully and see what the fish see. Don’t expect vibrant colors, though, as due to the refraction of light at that depth, everything looks sort of washed out. 

You likely won’t be getting any stunning, crisp photographs of marine life, but that’s okay — this one is more about the lived experience and being in the moment.

Cruise Ports with Submarine Excursions

My submarine adventure was in Aruba, but this is an activity offered in other Caribbean ports of call, including the following:

If you aren’t claustrophobic or nervous about plunging into the depths of the ocean, this is a really cool and unique experience that I encourage everyone to try at least once. It’s truly an unforgettable experience and a bucket list achievement!
