The Poisoned Glen, nestled at the foot of Mount Errigal in Donegal, is a stunning area known for its sweeping valleys, imposing mountains, and shimmering lakes. Legend has it that the name might have been lost in translation from Irish to English, with some suggesting it should actually be called the "Heavenly Glen." Another tale involves a one-eyed giant, Balor, and his beautiful daughter who was kept hidden away until she was kidnapped. The entrance to the glen is marked by a stone said to be the poisoned eye of Balor. With its rich history, breathtaking views, and musical influences, the Poisoned Glen is a must-visit spot for nature lovers and adventurers alike.
