There were incredible scenes at Sandycove last night as bioluminescence lit up the water.
The magical video, which was shared by Flossie and the Beach Cleaners, shows the water lighting up in incredible shades of blue and orange late last night.
Flossie and the Beach Cleaners said on social media: "Bioluminescence at Sandycove last night… one of our fab friends Rachel stayed until midnight to wait for it to glow … how amazing is nature."
