Rivers - Hidden Worlds Hidden Worlds is taking to the river to explore another aquatic habitat. Lorraine O'Donnell of Inland Fisheries Ireland gives us a comprehensive overview of our river systems. We meet her colleague Paul Condon by the gushing, rushing stream at Slish Wood in Co. Sligo and take a little break with Shailagh Healy to soak up the wonder of our rivers.

Hidden Worlds sees Ocean FM out and about across beautiful pockets of North West Ireland uncovering the inspiring variety of life that we share our spaces with, whether we are letting off steam at the beach, river or forest, bustling through town or out in the fields. So slow down a little and take a breath to marvel at the ordinary places, often overlooked, where plants and creatures thrive, regardless of our daily concerns.
