The Italian Naval Base Wrecks (Leros) | WWII Wreck Field
Site Overview
The Italian Naval Base Wrecks of Leros are a poignant cluster of sunken WWII torpedo boats and small freighters resting on the sandy seabed off the island’s historic naval base. Lying in 12–35 m, the scattered hulls and fittings have become a haven for macro life: morays and conger eels thread the openings, nudibranchs freckle the algae-covered plates, and wrasse patrol the wreckage. Although penetration is not encouraged, swimming the bright outer structures gives a strong sense of history without the risks of enclosed spaces. For divers interested in wartime archaeology, the Leros wrecks are a satisfying, fish-filled dive close to the Dodecanese, and the clear water makes the details easy to appreciate. It is a favourite of macro photographers and of anyone who loves a wreck with a story. The Italian Naval Base Wrecks (Leros) sits within Aegean – Dodecanese and is best described as a wreck and macro dive. The water here is typically clear, and the profile — from around 12 m down to 35 m — gives advanced divers a rewarding range of routes. Among the life you can expect are Mediterranean Moray, Conger Eel, Nudibranch, Anthias, Wrasse. The site rewards a slow, observant approach, and good buoyancy keeps both diver and reef safe. With sensible planning around weather and boats, it ranks among the more memorable stops on a Greek diving trip.
Dive Briefing
"The boat anchors uptide of the wreckage and the group descends along the shot line to the first hull. The guide circles the outside first, pointing out morays and congers, before allowing pairs to swim the open structures with a torch. Penetration beyond the bright doorway sections is prohibited. Divers maintain a slow pace to conserve gas for the 12–35 m depth and keep clear of sharp edges. The ascent follows the line with a three-minute stop, and a DSMB is deployed before surfacing. A line cutter is carried by everyone. The dive ends with a careful ladder re-entry. On the day, the guide runs a full briefing covering entry, descent line, depth limits and the turn point. Divers follow the plan at a relaxed pace, keeping close to the group and watching depth and gas. The route makes the most of the wreck and macro features while staying within no-decompression limits. A safety stop in the shallows rounds off the dive before a controlled ascent and DSMB deployment if needed."

Traveler Notes
Who is this for?
The Leros wrecks suit advanced divers comfortable at 25–35 m who want a wreck dive without serious penetration. They are also rewarding for macro photographers, thanks to the morays and nudibranchs, and for anyone interested in WWII history. Open Water divers can enjoy the uppermost sections with a guide, while the deeper parts are best for those with deep-dive training. Good buoyancy is important near the hulls. It is a good choice for advanced divers who want a mix of marine life and scenery without extreme demands. Photographers will find plenty to frame, and buddy pairs can explore comfortably once briefed. Those new to the area should dive with a local centre to make the most of conditions and site knowledge.
