Just a quick note reference Darrenf's mention of the new Cairn on top of Silsean.
Myself and some friends who live in Ballyknockan often walk in the general area of Silsean, Moanbane and Mullacleevaun. We were getting frustrated with the state of the summit of Silsean which had almost totally turned to a wet boggy mess because of the motorbikes and quad bikes which on an almost weekly basis would joyride all over this area.
We started to build the Cairn using stone from about 100 to 150 metres away in a northerly direction. We carried a lot of the stone by hand but also used a stretcher.
As well as building the cairn we also moved a lot of sods from lower on the hill to the summit in order to get some of the grass and other plants to take root and hopefully displace some of the water and make the ground "walkable" again.
We hope to finish the cairn his summer. We intend on making a beehive shape so it should be at least a meter higher and should be seen from further away.
Thankfully it seems that the biking has stopped since the signs went up for National Park at the forest gates above Ballyknockan.
If anyone has the energy or inclination they could always bring a small stone up the hill on their next walk! Linkback: https://mountainviews.ie/summit/113/comment/4592/
