Beyond the Seychelles' reef diving, a smaller but dedicated niche of visitors comes specifically for wreck diving — sunken ships that have become artificial reefs over decades, some intentionally scuttled to create dive sites, others lost to accidents or storms. For certified divers with some experience, it's a different kind of underwater experience from the granite boulders and coral gardens the Seychelles is better known for.

L'Union Bati

One of the more accessible wreck sites is L'Union Bati, a wreck dating back to the early 20th century now encrusted with coral growth and home to resident fish life that's built up around the structure over the decades. Wrecks like this function as artificial reefs — the structure itself gives marine life something to colonise that wouldn't otherwise exist on an open sandy or rocky seabed, often resulting in denser fish life around the wreck than on a comparable natural reef nearby.

What Wreck Diving Involves

Wreck diving generally requires more experience and caution than a standard reef dive — depth, potential currents, and the physical structure of a sunken vessel all add complexity that a dive operator will factor into who they take out to a given site. Some wrecks are suitable for open-water certified divers with a guide; others, particularly those with penetration diving into the wreck's interior, require specific wreck diving certification. It's worth being upfront with a dive operator about certification level and experience when booking, since not every wreck site is appropriate for every diver.

Choosing a Dive Operator

Wreck sites are generally reached by boat from Mahé or Praslin, with local dive operators best placed to advise on which wrecks suit a diver's certification and experience level, along with current visibility and conditions. Because wreck diving carries somewhat more risk than reef diving, it's worth choosing an operator with specific experience running trips to the site in question rather than a generalist reef-diving outfit.

Fitting It Into a Seychelles Trip

Wreck diving is a specialist add-on rather than something every visitor will want to prioritise — most Seychelles trips are still built around beaches, reef snorkelling, and island-hopping. Quintrip's Seychelles holiday packages can be built around a Mahé or Praslin stay with wreck diving arranged locally through a dive operator, and a consultant can help flag this as a priority when planning the trip.

Planning the Trip

The Seychelles' calmer season, roughly October to April, generally offers better visibility for diving of any kind, including wreck sites, while the southeast trade wind season from May to September can bring choppier conditions and reduced clarity. A Quintrip consultant can help time a dive-focused Seychelles stay around these seasonal patterns.

FAQ

Do you need special certification for wreck diving?
It depends on the wreck — some sites suit open-water certified divers with a guide, while wrecks involving penetration diving require specific wreck diving certification.

What is L'Union Bati?
An early 20th-century wreck now encrusted with coral and home to established fish life, functioning as an artificial reef.

Is wreck diving riskier than reef diving?
Generally yes — depth, potential currents, and the physical structure of a sunken vessel add complexity that requires more caution and experience.

How do you get to wreck dive sites?
By boat from Mahé or Praslin, arranged through a local dive operator experienced with the specific site.

What's the best time of year for diving in the Seychelles?
Roughly October to April generally offers calmer seas and better visibility than the May–September trade wind season.
