Lough Hyne Night Swim

If you have never visited Lough Hyne at night then you need to put it on your list. Better still get on or in the water and explore the amazing bioluminescence.

The weather Gods were smiling and presented us with perfect conditions for our annual Lough Hyne Night swim. The perfect conditions to see what many have come for; the luminous phosphorescence for which Lough Hyne is famous. This bioluminescence is one of the many rare attributes of this marine lake, fed by a tidal tap from the Atlantic.

Bioluminescence is the production and emission of light by a living organism. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies.
