I came from Old Kilcullen and turned right out onto the main road N81 going back towards Dublin, where the road widens there is a spot to safely pull in about 100 yards after from the last house on left. There is a bit of a gate to hope with a sign saying that "this is a farm etc no liability". Then just walled up the hill. Lot of sheep in the fields at the moment so its safe enough. There were a few cows within the bank could be a bit unpredictable this time of year.
