Chania Scuba Diving | Boat Dives | Certified Divers

If you’re planning a trip to Crete and love exploring under the surface, you’ll want to check out this guided boat diving experience offered by Kefi Divers. While we haven’t personally been on this exact tour, we’ve gathered plenty of insights to help you decide if it’s a fit for your underwater adventures. What really catches our eye about this experience are the small group sizes—limiting to just 4 divers per instructor—and the crystal-clear waters that Crete is famous for. These factors promise a relaxed, personalized trip with plenty of room to enjoy the marine sights.

One thing to keep in mind is that this tour is designed specifically for certified divers. If you’re new to diving or not certified, this might not be the experience for you.

Dive Sites: Variety & Highlights

Your dives change daily, which keeps things fresh. Two sites stand out in reviews:

• The Elephant Cave: A true highlight, this submerged cavern contains stunning red and white stalactites. It’s not just a natural wonder but also a dive through geological history, with fossilized remains of extinct elephants. Divers love the sense of exploring something quite surreal and historic underwater.

• The Artificial Reefs at Ombros Gialos: Crete’s newest dive site, featuring 44 reef structures placed onto the seabed, offering a protected haven for marine life. The creation and recent sinking of the ship in April 2025 mark this site as a growing underwater park, adding a layer of intrigue for those interested in marine conservation and artificial reefs.
