Please note - as mentioned by Paddyobpc in another comment (on page 2) - the location labelled A and referred to as "Castleblagh Forestry Entrance" on the map indeed bears no relation to the main forestry entrance outside Ballyhooley. Uncannilly, both entrances referred to in the Knocknaskagh posts have room for about five cars each (as mentioned by others - for both) which only makes it more confusing. To cut a long story short I got there, eventually, but was too whacked battling through trees trying to find my way to even consider the north top - for another day hopefully. The venture was worth it though to see a red squirrel dart across the forest trail about ten yards in front of me. The most bushy-tailed, most gorgeous fiery red you could imagine. That made the day.
To compound the confusion regarding location, the official forestry entrance has a board map, but if you look at it closely you will see that the "You Are Here" arrow points, not to "here", but to "there"! This is because the arrow is pointing, not at the main entrance where you are but to a lesser entrance a kilometre or two back the road towards Ballyhooly - you couldn't make it up. You need your whits about you to tackle this one. Linkback: https://mountainviews.ie/summit/702/comment/20429/
