No need to go route A here, there is a path all the way but you will have to cross a stream and bring either a ladder, an etrier, ropes or a pair of shoulders to stand on - I used an etrier and a couple of slings. Once up the first bit it's an easy grab and easy to see from the ground.

Coillte advocates ‘Leave No Trace’ as their user behaviour code while visiting their forests. Leave No Trace is an educational approach to visitor behaviour and is endorsed by all major public landowners and practically all representative user groups in Ireland. Its principle is that everyone takes responsibility for their actions while visiting our forests, thereby ensuring the protection of their forests and natural environment while being mindful of the enjoyment of others.
