Tá cnoc i dTiobraid Árann.... (There is a hill in Tipperary..... - but I have difficulty understanding the rest of the sentence) agus ní fhéadfá gan é a thabhairt fé ndeara pé deabhadh nó deithneas (haste nor hurry?) a bheadh ort ag gabháil thar brághaid duit.

The original version in English doesn't seem to correspond to it. -

In Tipperary is one of the most singularly shaped hills in the world.

...and you couldn't help but notice it (lit. 'couldn't not notice it') regardless of whatever haste or hurry would be on you going past/by it.

And "brághaid" would be spelt "bráid" in modern spelling.

Go raibh maith agaibh.
This is the first story in 'Fairy legends and Traditions of the South of Ireland' compiled by Thomas Crofton Croker - 'Cnoc Síodh-Ghamhna - The Legend of Knockshegowna' also known as 'The Hill of the Fairy Calf' put into verse by Charles Causley. Apparently it was collected from one William Maginn. This is the re-translation back into Irish by Brighid Ní Loinsigh in her book 'Síobhraí na mBeann is na nGleann.' She seems to have recreated her own version in Irish rather than staying with that of Croker and Maginn.

The more I look at this, the more it looks as if the version in Irish is completely different from the English version. Anyway in French, this is what I've written:

Il y a une colline dans le Tipperary et vous ne pourriez pas, quel que soit votre hâte ou votre empressement ne pas la remarquer en passant.

Here another expression - san tráth den tsaoghal - literally - in the time of the life - but what does it mean here? I can understand the rest of the sentence.

Síodh-thalamh ab eadh an cnoc san tráth den tsaoghal (tsaol), agus is mó oidhche (oíche) bhreágh (breá) spéir-ghealaighe a chaith an sluagh sidhe ag rinnce is ag aoibhneas dóibh féin ann.

... in those days.

Go raibh maith agat

Franc, 'san' here is not 'in the' but the Munster version of 'sin', and goes with 'an cnoc' - 'that hill/mountain'.

The expression is 'tráth den tsaol' - 'at one time', as well as Bríd's version.

Ah OK, I hadn't realised that. Go raibh maith agat.
