It is a very popular location for swimming, diving and kayaking, particularly night kayaking to witness the bioluminescence for which this sea-lake is famous.
Microscopic organisms called phytoplankton store up light energy in the day then release it when disturbed by night. This light, called bioluminescence needs total darkness. When the kayak paddles break the inky black surface of the lake, the light show begins, like fairy dust, quite a magical spectacle and one which must be seen by the naked eye as it would be quite difficult to photograph or record without specialised equipment. An opportunity for a unique digital detox experience!
Bioluminescence can be seen all along the West coast but the stillness of Lough Hyne is what makes it particularly spectacular here.
