Diving Minnewaska with Kefi Divers
At the entrance to Souda Bay near Chania lie the remains of SS Minnewaska III, a transatlantic passenger liner that became a First World War troop transport before striking a mine in 1916. Today, its surviving structure forms an accessible recreational wreck dive with a remarkable story.
This is not an intact ship and it is not a penetration wreck. The attraction is the meeting of maritime history, exposed structure and marine life across a compact area of sandy seabed.
SS Minnewaska III — quick facts
Location: entrance to Souda Bay, near Chania, Crete
Depth: approximately 12–19m; maximum approximately 19m
Access: boat only, followed by an underwater line to the wreck
Certification: Open Water or equivalent, when appropriately guided and comfortable with conditions
Wreck condition: largely broken up; no penetration routes
Harland & Wolff built Minnewaska in Belfast for the Atlantic Transport Line. Launched on 12 November 1908 and entering service in 1909, the approximately 183-metre, 14,317 GRT liner carried passengers on transatlantic routes.
The British Government requisitioned the ship in January 1915 for use as a troop transport. Australian War Memorial records connect Minnewaska with the transport of Australian troops for the Gallipoli campaign, one of several wartime voyages associated with the Dardanelles.
On 29 November 1916, Minnewaska struck a mine at the entrance to Souda Bay. Captain Thomas F. Gates brought the damaged vessel into shallow water, allowing everyone aboard to be evacuated. The Australian War Memorial records no loss of life.
The damage made economical recovery impractical. Minnewaska was declared a total loss and its structure was later salvaged and broken up in situ. Historical accounts disagree on the exact number of troops aboard, so this guide does not present a disputed figure as certain.

Length: approximately 183 metres
Gross register tonnage: 14,317 GRT
What divers see today is a field of surviving structural remains concentrated in one area, rather than the outline of an intact liner. Sections of hull and exposed ribs rise from the sandy bottom and make the scale of the original ship tangible.
The vessel was salvaged and broken up where it lay, and time beneath the sea has further reduced the structure. There are no rooms or enclosed routes to enter.
Broken hull plating and exposed structural ribs of SS Minnewaska III
Surviving hull plating and ribs show the wreck’s broken-up condition.
No wreck penetration
SS Minnewaska III has no penetration routes. The dive stays around the open structural remains.
The wreck extends from approximately 12 metres to a maximum depth of about 19 metres. That profile places it within Open Water depth limits.
Depth alone does not determine whether a dive is suitable. Certification, recent experience, comfort, air consumption and the day’s conditions are considered when planning the dive.
There is no surface marker directly above the wreck. Kefi Divers anchors or moors in shallower water near the start of an underwater line, then follows that line with the group for approximately five minutes to reach the remains.
The wreck lies over a sandy bottom and there is generally little to no current. Visibility can sometimes be lower than at Kefi’s other sites because fins or poor buoyancy can disturb the fine sediment.
Open structural ribs of SS Minnewaska III above the sandy seabed
Open ribs and broken plating are spread across a concentrated area of sand.
Time at the wreck depends on the group’s air consumption. The dive plan always retains enough gas for the return swim along the line and a controlled ascent.
Buoyancy matters
Good buoyancy protects the remains and keeps fine sediment off the sandy bottom, helping everyone maintain clearer visibility.
Lionfish and nudibranchs are regular sightings among the structure. As with any natural dive site, encounters vary; the history and wreckage remain the main focus.

Low structural remains rest across the sandy bottom near the entrance to Souda Bay.
Kefi Divers takes Open Water divers or equivalent to Minnewaska when their experience, comfort and the conditions are appropriate. It is not an advanced-only site solely because of depth.
The guided route remains outside the wreckage. There are no penetration routes, and divers should be comfortable controlling buoyancy over a sediment-covered bottom.
Minnewaska is one of Kefi Divers’ regular boat-diving sites and is normally visited as the second stop on a relaxed two-dive trip using two different sites:
First dive — Marathi Island: a Mediterranean reef to approximately 20 metres and one of our favourite sites for finding octopus.
Second dive — SS Minnewaska III: historic First World War wreckage at approximately 12–19 metres.
Small groups allow the guide to adapt the pace and dive plan to the divers present. Current options, prices and booking availability are shown on the certified boat-diving experience page.
