Picture: Big TV tower on flattish ridge.
Mullaghanish is a boggy, wet, flat topped hill on the Cork/Kerry border. Its summit is home to a huge TV mast and associated infrastructure. While it may be a nondescript summit, it is a fine vantage point with views across to The Paps, Caherbarnagh and Crohane.

S. For an easy walk it is possible to park at Mull Tr Gt (W20455 79903), and climb via the RTE access road. This should take about 45 mins and involves nearly 400m ascent.

SE. Park at a forest access area Kn'ulane (W22369 80417), room for 10 cars. Cross the road and head north with the forest to your right and a fence to your left along a grassy boggy track. Take this up to Carrigrathduff, then head straight for the peak over more heathery terrain. You will need to hop a fence or two. Heading for Mullaghanish, you'll run into a tall barbed wire fence. To avoid it, follow the fence NE for a couple of minutes, and a gate appears. You can go through here and get to the peak. The best way back down is to retrace your steps. Allow 1hr+ to the summit.

Track/3788 is noteworthy and includes two satellite tops to the NE.

The most famous summit in the SW?
by Conor74 8 Feb 2012
Right up there anyway, though perhaps only amongst a certain generation. And I say that conscious of Carrauntoohil's height and Brandon's pilgrimage. I think I made this comment to Simon last weekend as we were on its slopes and as it amused him, so it may amuse you to know of its fame. Before I ever picked up a geography book in national school and learned about mountains I was a fan of the tv. Its been a long running affair, if anything it has deepened over the years. Anyway, as a child in the mid to late 70s, we had the grand total of 2 channels on a black and white telly. And we and all of my age lived in the fear of that dreaded message that regularly flashed up on our screens..."we apologise, there is a problem with our transmitter at Mullaghanish...". So when I say most famous summit in the SW, I mean amongst the people of the SW. It was almost like a mantra, everyone knew of this summit, it was pointed out to every wide eyed kid as the family drove over the county bounds between Cork and Kerry, it was a marvel of engineering and technology to us all, almost up there with Kerry Airport and the Dursey Cable Car.

Anyway, some facts lifted from

Because of the mountainous nature of the area served, it has the highest amount of relays for an Irish transmitter. That site says this is a "dubious honour"...I have to concede I don't actually know what this means!

It transmitted RTE's first attempt at regional television, in the early 1970s, with the programme Munster Matters. This was produced in Dublin and transmitted after RTE shut down at night, when Mullaghanish was the only transmitter that stayed on. The experiment failed, and so RTE stopped regional programming for decades afterwards.

It was one of the 5 original Teilifis Eireann transmitters, opening in 1962. Linkback:

An alternate route to the RTE access road: After turning off the N22, follow the small blue signs directing you to Mullaghanish. Drive about 2.5 km past the tower road, and park at a forest access area facing south ( Kn'ulane (W224 804), it doesn't look like it reaches the road, but it's there). Head north with the forest to your right and a fence to your left. There isn't a trail marked, but it's pretty easy going over slightly mucky grassland. Take this up to Carrigrathduff, then head straight for the peak over more heathery terrain. You will need to hop a fence or two. Heading for Mullaghanish, you'll run into a tall barbed wire fence. To avoid it, follow the fence NE for a couple of minutes, and a gate appears. You can go through here and get to the peak. The best way back down, unfortunately, is to retrace your steps. The aesthetic value of this mountain would be poor even if the transmitter wasn't there, but the views of the Paps and the surrounding valleys are great on a nice day.

The OSI map shows another trail heading north towards the top from the road at A (W221 807), but it's very muddy and is clearly a private road. I'd avoid it if possible. Linkback:

mart on Mullaghanish
by mart 6 Jan 2005
You can climb this mountain on the road that leads up to the RTE transmitter on the summit. The mountain is big and round and I don't know of any good reason for taking a different route. The summit route is found from a minor road that runs from Ballyvourney to the Macroom-Millstreet road at about 1400ft so the climb isn't too far. The view should be extensive on a good day. The summit stands on the Cork-Kerry border and looks down to the Blackwater, Clydagh and Lee valleys Linkback:

paulocon on Mullaghanish
by paulocon 29 Aug 2009
Took a walk up the access road to the summit of Mullagnahish with the young'uns while on holidays last week. The mountain (or a route of some sort) is signposted from Ballyvourney (take the road on the Killarney end of the village) but isn't signposted from then on so follow the cycle-route signs and you'll find the way. Grand walk from the locked gate but unfortunately the summit is literally a hard-hat area as it's currently a pretty messy-looking building site. Good views across to the Paps on the ascent but unfortunately by the time we had reached the top, a thick mist had come across. Not much to recommend but one of the easier 'Dillon' summits. Linkback:

A dry day at last.
by three5four0 4 Oct 2011
Parked up at the side of the gates at Mull Tr Gt (W204 799), and followed the mast access track to the top, in what was one of only 3 sunny days we had on a 12 day trip to Kenmare. Lots of work going on around the masts and the assorted buildings of the summit area.

Took the picture on our descent, the high cirrus indicating another weather front was on its way. Linkback:
