Scuba Diving in Colombia: Do Not Miss Those 3 Spots

Scuba Diving in Cartagena and the Undersea Museum

Cartagena’s colonial streets might be its postcard face, but under the surface lies an entirely different kind of treasure. Scuba diving in Cartagena reveals a vivid marine world shaped by both nature and history.

I joined Cartagena Divers, a relaxed and friendly company that knows how to blend professionalism with a laid-back vibe. Our trip included two dive sites close to each other.

PADI is recognized worldwide, so your certification works pretty much anywhere.

The first, the famous Undersea Museum, is home to several shipwrecks resting silently in the sand. Exploring them feels like stepping into another world frozen in time.

We visited three wrecks, each covered in marine growth, creating a surreal blend of history and sea life. If everyone in the group has the right certification, you can even swim inside. The narrow passages, filtered sunlight, and mysterious shadows make the experience unforgettable.

The second dive site, near a cliff, offered incredible biodiversity. I spotted lionfish gliding like slow-moving hunters, moray eels hiding in coral crevices, and colorful crabs moving gracefully across the reef.

The corals were still vibrant, but I couldn’t ignore the whitening patches, a stark reminder of how warming seas are challenging these ecosystems. It made me appreciate even more the living reefs still thriving near Cartagena.

When I’m planning my trip, I always check flights on Skyscanner first, since it lets me compare prices and find the best deal, and most of the time I also go on Trip.com afterward, which is another great price comparison tool for flights and hotels.
