A compact 3 1/2 hour walk that takes in the highest point of Donegal and its smaller neighbour. The route follows the 'Tourist Trail' to ascend Errigal, and uses both boggy and rocky tracks. Care needed if windy due to steep slopes. The narrow path between the two 'summits' of Errigal is brief and not really that narrow. Again be careful if it's windy. Fine views across the land and to nearby mountains. Good car park at start of route, and great views of Errigals precipitous northern slopes while ascending/descending Mackoght.
