The Poisoned Glen is a valley accessible from the park with a map or GPS. You can connect it by the R521 but the R524 is the easiest access. The valley lies at the foot of Errigal Mountain (a beautiful rocky mountain) and Dunlewey Church (a ruined church of surprising and enigmatic beauty).
The valley can only be walked, and requires good hiking boots (some parts are quite muddy), as well as the obligatory minimum for walking (backpack, windcheater, food, water and all). The place is superb, immensely green and quiet. A perfect valley for a change of scenery, which will amaze you with its majestic mountains.
Don’t hesitate to walk through it: the desert aspect of the Poisoned Glen will take you back to the time of the Irish Gaelic clans, where people wore kilt and ventured freely in the Irish wild valleys. Miles and miles of lush green moorland await you!
