Night Diver

The Night Diver specialty course runs one day at $149.99 and earns a PADI specialty certification. Night diving changes the underwater environment in ways that daytime diving doesn't prepare you for: the same reef sites look different when illuminated only by torch, marine life that hides during the day comes out, and spatial awareness demands more attention without visible surface light for orientation. Cartagena's waters are specifically mentioned by the center as a place where bioluminescence occurs — planktonic organisms that glow when disturbed, visible when dive lights are switched off. It's not a guaranteed phenomenon, but when conditions are right, it's one of the more unusual things you can see underwater.

The one-day structure means this is a concentrated experience rather than a multi-day progression. Students learn night diving procedures — pre-dive briefing protocols, light signaling conventions between buddy pairs, navigation in low-visibility conditions — and put them into practice on an actual night dive. The minimum age is 12, the same as several other specialty courses at this center.

For divers who have completed the Open Water certification and want to add a specific skill set without committing to the full Advanced Open Water track, specialty courses like this one are a practical way to build a more varied dive log. The Night Diver certification also counts as one of the five adventure dives required for the Advanced Open Water Diver certification if taken in that context.

The center also runs night diving guided tours separately from the certification course, so divers who want the experience without the credential have that option. The one-day course format allows this to fit into a short stay in Cartagena — it can be added onto an existing trip without needing an extra travel day.
