Laon Egen Hir
A chain of caves lined with jewel anemones in shallow stones
Laon Egen Hir is a field of stones in the southeast of the Glénan archipelago and one of its best-known dive sites. The rock runs from the surface down to 18 m and hides a chain of caves whose walls are coated in jewel anemones.
Also known as Laon Egenn Hir.
Where it is and how deep
No published position for this site — the map shows Glénan Archipelago and its other sites; operators know the mooring.
The dive
The stones begin right at the surface and continue down to 18 m, so the whole route stays in the shallow band. Divers work their way through the boulders to the chain of caves that threads between them, where Corynactis jewel anemones in many colours cover the rock and turn the cave walls into the main sight of the dive.
