My outing to Castlemahon summit.
by Ulsterpooka  12 Oct 2017
I followed Peter Walkers route and asked permission to walk to the summit mast. The person was very friendly and accommodating. I parked at the last house in what is a four house dwelling lane. The second last house has 'Joe' in centre of the metal gate. I assume a reference to Joe's mountain on a stone Boulder further up. I followed the track until the mast and found the trig pillar nearby. The Mourne mountain range can be seen as well as Strangford Lough and the Isle of Man on a good day.
