San Andrés: Meet the Semi-Submarine Nautilus

Few places in the Caribbean offer a more colorful, lively underwater scene than San Andrés Island. For just $36 per person, you can spend about two hours exploring the coral reefs in a semi-submarine called Nautilus. The experience departs from Marina Portofino, and it’s a fantastic way to see marine life up close without even getting your hair wet.

What we love about this tour is how accessible it is for families and travelers of all ages. The panoramic underwater windows give you an immersive view of the reefs while keeping things comfortable and dry. Plus, the inclusion of a refreshing swim next to schools of fish adds a hands-on element that makes the whole trip memorable. The tour is guided, so you’ll have easy explanations and insights along the way—perfect for those who want a bit of education alongside the fun.

One thing to consider is that this activity isn’t suitable for people with mobility impairments. The experience is smooth and straightforward, but if you have trouble with stairs or standing for long periods, this might not be the best fit. Also, since it’s a semi-submarine, it’s less about active snorkeling or diving and more about observing from a comfortable vessel—great for those who prefer a relaxed experience.

This tour suits families with children, first-time visitors, or anyone who simply wants a safe, scenic way to enjoy San Andrés’s underwater beauty without fuss. If you’re looking for a quick, engaging introduction to the marine environment, this is an excellent choice.
