The one in Ballycroy National Park.
On the road between Mulranny and Ballycroy, there is little lay-by with parking for 15 cars called Cleggan. It is the starting point for a most enjoyable board walk.
That board walk was entirely funded by the International Institute for the Study of Midges Feeding Habits.
Thankfully there was a most pleasant (if not life-saving) gentle breeze as we ventured deep into midge territory on a gloriously sunny morning.
