I used to ride this as an alternative to the highway when coming back from Mt Lindsey or Queen Marys falls. After the town of Rathdowney (I have been to the original in Ireland) you come to Tamrookum and can turn off to Hill end. Check the map below but there are a few back roads here to string together if you have the time. Also you can join onto the road to Kerry if returning or going to the Lions road so no reason to ride the Beaudesert highway if didn’t want to.
I have removed the original post as it was too old, please see the map for location of this road.
