Using an OS map it is easy to see that a long bye-road goes up most of the way up the hill. The road is pretty bad and there a number of gates on it as it is a farm track. Depending on the weather, if it is wet best to park before the first gate as there is no real alloted parking. Follow the track up the hill, the soil in the area seems to be an orangey/red.
Views from the top of the hill are amazing looking all over limerick, south-tipp and down into kerry (I think). I could pick out my own hill tountinna in north tipp here. The cross and the tv masts however really take from the hill and the cairn on top is pretty disappointing. However the mythology attached to the hill and the views more than makes up for it.
The hill of the fairies. This is the loftiest mountain in the county abovenamed, and lifts its double peak on the Southern side, pretty accurately, I believe, dividing it from Cork. Numberless are the tales related of this hill by the carmen who have been benighted near it on their return from the latter city, which is the favourite market for the produce of their dairies. That there is a Siobrug or fairy castle in the Mount, no one in his senses presumes to entertain a doubt. On the summit of the highest peak is an unfathomable well, which is held in very great veneration by the peasantry. It is by some supposed to be the entrance to the court of their tiny mightinesses. A curious fellow at one time had the hardihood to cast a stone down the orifice; and then casting himself on his face and hands, and leaning over the brink, waited to ascertain the falsity of this supposition by the reverberation, which he doubted not would soon be occasioned by the missile reaching the bottom. But he met with a fate scarce less tragical than that of poor Pug, who set fire to the match of a cannon, and then must needs run to the mouth to see the shot go off. Our speculator had his messenger returned to him with a force that broke the bridge of his nose, locked up both his eyes, and sent him down the hill at the rate of four furlongs per second, at the foot of which he was found senseless next morning.
"Knock Firinn is called by the people of the country 'Knock Dhoinn Firinne,' the mountain of Don of Truth. This mountain is very high, and may be seen for several miles round; and when people are desirous to know whether or not any day will rain, they look at the top of Knock Firinn, and if they see a vapour or mist there, they immediately conclude that rain will soon follow; believing that Donn of that mountain and his aerial assistants are collecting the clouds, and that he holds them there for some short time, to warn the people of the approaching rain. As the appearance of mist on the mountain in the morning is considered an infallible sign that that day will be rainy, Donn is called 'Donn Firinne,' Donn of Truth."
In 'Fairy Legends and Traditions of the South of Ireland' by Thomas Crofton Croker (1828).
"is traditionally known as the 'Hill of Truth'. It is said to personify Donn Fírinne, the Celtic God of death and fertility. In folklore he is seen as a giant or the Fairy King. He is said to live at the bottom of a deep hole in the hillside called 'Poll na Bruinne' and anyone trying to investigate this entrance to the Otherworld will not come away unscathed and may even be drawn in, never to be seen again. There are many cautionary tales to deter the curious. However, good custodians are rewarded. One local farmer was granted temporary entrance to Donn's world under the hill where he met with a brother and sister, both of whom had died many years before.
Donn is closely associated with weather omens. He is said to collect the clouds on his hill and hold them there for a while to warn of approaching rain. Sometimes he is said to be in the clouds if the weather is particularly bad. He is also said to be flying abroad when someone dies.
There is a cairn on the top of Knockfeerina called 'Buachaill Bréige', meaning 'the false or lying boy' and it was the custom, and indeed the duty, of local people, to carry a stone up the hill to put on this cairn once a year. The hilltop has traditionally been a popular Lughnasa assembly site visited at harvest-time, and at this time freshly picked berries and flowers were strewn around the cairn as offerings for the hill's fairy inhabitants. On the eves of the festivals of Bealtaine and Samhain, young girls used to leave gifts high up on the side of the hill below the western ridge called 'the Stricken'.
Like the hills to the east, Knockfeerina is also associated with the adventures of the Fianna. On the Stricken is a large ring-fort called 'Lios na bhFian' or 'Fort of the Fianna'. One such adventure is named after the 'Palace of the Quicken Trees' where the Fianna become the victims of an act of revenge after being lured to a feast in an imaginary palace.
A little wary of the invitation, Fionn had left his son Oisin and a number of the Fianna behind. And sure enough, while they waited for the food to arrive, the fire began to send out black clouds of evil-smelling smoke. The palace around them disappeared and they found themselves sitting on the hillside and fixed to the ground, unable to rise.
Fionn put his thumb to his month, which he did when he wanted to see to the heart of things, and found that the spell that held them had been cast by the three kings of the Island of Torrent. These kings where marching on the palace to kill them and only the blood of these three kings could undo the spell.
When Oísín and the other Fianna came to see if they were alright, Fionn warned them not to come in. He explained what they must do to stop the kings. Evenutally the Fianna managed to intercept and then kill the three kings. They took their heads and sprinkled the blood around their companions. Thus the spell was broken.
Issues of revenge and death are common in Fianna stories. This particular story also illustrated the dark side of Knockfeerina and its reflection in the human psyche. On a lighter note, folk tradition has it that Donn and his followers fought battles on behalf of the countryside. They might take the form of a cross-country hurling match against the fairy people of Knockainy. The winner would take the best of the potato crop to their side of the county"
I never got to see this tomb the last time I went to Knockfeerina. This time i got here just as the sun was beginning to go down and although it was a beautiful time of the evening it wasn't great for photography with my camera.
To get there, take the track leading up to Knockfeerina and where it branches off at the bottom of the hill take the left branch.
Follow this until it ends and you should be able to see the tomb away in the distance to your left over one ditch.
The tomb itself is big, I measured it roughly 11m long by about 2m wide. It is aligned East-West with the east end pointing towards a rock outcrop.
