Start at R 983 089 A where there is a decent carpark .
Cross the tarred road at the carpark and you will see a track leading east across the bog which leads you onto the main Avondhu way track,
You can also turn north on the tarred road and walk 200 meters to where the Avondhu way crosses the road.
Once on this rocky way follow it uphill for approx 2 kms until you gain a plateau at 600 mtrs elevation.
The track at this point can be followed straight ahead(north) or to the right(west).
Turn right and cross the plateau until the track starts to go downhill again at a waymarked way post.
Turn north here for the summit co-ordinates.
This gives you the easiest line of ascent to the summit.
Manmade standing stones are visible around the trig pillar with a massive stone mound behind.
This was known locally as the heap of stones, above the valley known as the Prisun.
Most of the stone is banked higher on the north side with a lower bank of stone to the south.One or two suggestions have been made regarding the heap - they were collected so that a fire could be lit to welcome some British monarch - very unlikely. Firewood is non existent up here. The other one is that they were used as signal fires, lighting fires on hilltops is well documented in relation to the druids and earlier. Remember St Patrick and the fire on the hill of Tara. There are little cells built into the stone, this heap would have provided some protection from the weather and would be manned permanently .

Most walkers visiting the Knockmealdowns are likely to head for the eponymous mountain by way of the Sugarloaf with the starting and finishing point at the Bay Lough car park. The lesser visited western hills of the range are well worth visiting too. We started and finished at the Crow Hill car park (A in the map) and we did a circular loop taking in Knockclugga,Knockshanahullion and Knocknalougha. It is an easy 12 km hike without any significant ascents or descents.

There are a couple of curious man-made rock sculptures near the summit of Knockshanahullion: one is a dolmen about four feet high and the other, standing proudly erect a small distance away, is an unmistakable phallus shaped creation made from three stones and is about six feet high. Do they date from the megalithic period perhaps? Was the phallus shaped one the site of some ancient annual fertility ceremony involving druids and maidens cavorting in the nude? Alas, no. I assumed they were created in the last year or so but I was surprised to see a photo of the dolmen in Simon 3's report from 2003 in which he described it as "modern-megalithic" :-) The fact that it has remained intact nineteen years on is impressive and a credit to the people who built it. I don't know if the other one was there in 2003 or if it's of more recent vintage but they are both interesting and amusing curiosities and worth checking out.

A note for those intending to travel to the Crow Hill car park from the south: I drove from Carrigtwohill in East Cork and the satnav took me through a torturous route via Conna and Araglen. Avoid. Instead, take the M8 as far as Mitchelstown and thence via Ballyporeen. Linkback: https://mountainviews.ie/summit/188/comment/23708/

Knockshanahullion is readily reached from the same place as Farbreaga, namely the road at R 983 089 A. Incidentally, this road at 450m is easily the highest of the passes across the Knockmealdowns. Follow the Avondhu Way until you come to Knockclugga. Cloghy means a stony place and there are certainly stones all around. This irreverent monument from the “modern megalithic” period was standing on Knockclogga in early 2003. Linkback: https://mountainviews.ie/summit/188/comment/350/

Nice walk today, Started at carpark above Bay Lough (plenty of parking) at S031101 B, from there follow the Avondhu way west (head towards statue west of carpark to get started) as far as S016097 C, you are now leaving county Waterford and entering the Premier County. On the way to S016097 C you'll pass on old broken style at the edge of a forest at S022094 D, this is where you'll rejoin the Avondhu way from the top of Knocknalougha.
From S016097 C follow the posts to the top of Knockshanahullion S000105 E.
From the trig point at the top of Knockshanahullion, head for the top of Knocknalougha S020100 F, this isn't terribly steep, but can be very slippery, be warned, I almost ended up on my a** a few times. When heading towards Knocknalougha, if you encounter a fence running east-west, keep it on your right it will lead you almost all the way to the flat, fairly uninteresting summit, now stop and enjoy the views (30m visibility today so no views for us).
From the summit head south to S022094 D and retrace your steps to the car park.
A possible alternative that I haven't tried is: from Knocknalougha summit, head north to S017115 G where you'll meet a rough path, follow this path east then south to Bay Lough and follow the trail back to S031101 B to the car. Linkback: https://mountainviews.ie/summit/188/comment/6657/

The Eastern Knockmealdowns viewed from Knockclugga near Knockshannahullion.
Knockaunabulloga is just left of centre , the Avondhu way coming from the Vee gap skirts along the edge of the forestry visible below.In the background you can see the Sugarloaf with the ridge to Knockmoylan and Knockmealdown. Linkback: https://mountainviews.ie/summit/188/comment/1437/
