THE LINE

Old fields and the voices of the glen.

The recording begins at the graveyard at An Baile Dubh, Ballyduff, by the northern entrance to Glennahoo, and follows an old road south into the hills. It climbs over Beenbo, reaching 472 m, before turning east into Macha na Bó, where the river winds between steep green walls. Ruined houses and intact field boundaries line the long return north beside the water.

Mary’s house and the old fields

The Dineen and O’Donnell families are remembered in local walking accounts as having worked this glen. Rob identifies the photographed ruin as the house of Mary O’Donnell, known as Mary ‘Macha na Bó’. The remaining walls give those names a place in the landscape.

Those boundaries are on the record. The Archaeological Survey lists the field system as KE035-078, on the level floor of the Glennahoo valley, and inside it the foundation of a circular drystone hut, 4.55 metres across and standing 0.8 metres high. The recorded line passes within about sixty metres of it.

The church that went

The graveyard the walk starts from once had a church beside it. In 1615 the parsonage of Balliduff was recorded as waste and worth nothing; seven years later it was still on the list of parochial churches in the diocese. Remains of the building were standing in the graveyard around 1837 and by 1841 there was no trace of any of it. Fifty metres from the start, and gone inside four years of somebody writing it down.

An Béiceachán

A voice from Macha na Bó survives in the Schools’ Collection. Nora O Donnell told a story of An Béiceachán, a frightening presence heard around the hills. In her account, Paddy O’Donnell was returning from Glenahue when he heard it and ran home, only to find it already at the door. He sheltered in a nearby hayshed. It was said never to cross the river. This is local folklore, recorded with the teller’s name and address.

The name on the record

The Placenames Database records Macha na Bó as Maghanaboe in English, and an 1841 note explains it as the field or bawn of the cow. A field system and a hut on the valley floor is the ground that name describes.

01An Baile Dubh graveyardThe loop begins at approximately 63 m and follows the old road south into Glennahoo.
02Old turf roadA steady climb gains height above the northern valley and opens views towards Tralee Bay.
03Beenbo high groundThe recording reaches 472 m on the broad mountain shoulder above Macha na Bó.
04Descent to the glenThe route turns east across rough ground before dropping carefully towards the valley floor.
05Macha na BóThe return follows the river through the valley, beneath steep slopes and past old field walls.
06Ruined homesteadsStone ruins and the long valley track lead north towards the recorded start.

The field system and hut are Archaeological Survey record KE035-078, described in J. Cuppage, Corca Dhuibhne: Dingle Peninsula Archaeological Survey (1986), no. 1403. The distance is measured from the recorded GPX to the published coordinate. Nothing in the record ties those remains to Mary’s household, or dates the walls to the name. The Irish name, English form and 1841 gloss are in Logainm, record 22469 ↗. The farming families appear in the Dingle Hillwalking Club’s account of the glen ↗. Nora O Donnell, aged 45 with a Macha na Bó address, is the informant for An Béiceachán, Schools’ Collection, volume 0430, page 152 ↗. Ballyduff church and graveyard are Archaeological Survey records KE035-066 and KE035-066001, with the 1615 Royal Visitation, the 1622 list, Lewis (c. 1837) and the 1841 Ordnance Survey letters quoted in the Survey entry, described from J. Cuppage, Corca Dhuibhne: Dingle Peninsula Archaeological Survey (Ballyferriter, 1986). Rob identified Mary’s house and the rock locally called Cac Ar Seasamh.

HAZARDS & OPTIONSKnow the commitment.

The high section crosses open, exposed mountain ground where cloud can obscure the route and valley edges.

Bog, wet grass, rough track and loose rock can be slippery or slow after rain.

The slopes above Macha na Bó are steep and broken by cliffs, gullies and stream channels; keep well back from drops.

Streams can rise quickly after heavy rain. Do not force a crossing when water is high.

Livestock graze throughout the route. Give animals space, keep gates as found and do not bring a dog unless current access rules clearly permit it.

The final approach uses a narrow road with very limited parking and occasional traffic.

Before the high point, the simplest retreat is back down the known old road towards Ballyduff. Once committed to the descent into Macha na Bó, follow the recorded line and established track through the glen; do not improvise a shortcut over the steep valley sides. Turn back early if cloud, wind or rising streams remove a safe margin.

Getting there.

Where it starts, the recorded file, and the checks worth making before you leave the house.

PLAN THE GROUND

Start well.

RECORDED STARTAn Baile Dubh graveyard

Select coordinates to copy

The recording starts at the graveyard at An Baile Dubh, Ballyduff, by the northern entrance to Glennahoo. Parking is extremely limited on narrow rural roads: find a safe, legal space without blocking homes, gates, farm access or the road. The route crosses working farmland and open mountain. Respect every sign, gate, fence, animal and landowner, and check current access locally before setting out.

ROUTE FILE

721 recorded track points, exactly as walked. Load it into your watch, phone or offline mapping before you leave signal.

Distance, track geometry and elevation come from Rob’s supplied GeoJSON; recorded time comes from the supplied GPX. The recording was completed on 6 July 2025. Historical and placename sources are listed with the route story. Access and conditions must be checked independently.

Onto a watch: import the GPX into Garmin Connect, Komoot or Strava and send it to the device from there. On a phone, the Garmin Explore and OS Maps apps take the file straight from the share sheet.

BEFORE YOU GO

A quiet valley behind exposed high ground.

The old tracks are inviting, but the crossing between them needs mountain judgement.

Macha na Bó is enclosed by steep slopes and the loop reaches open mountain above them. Carry suitable mapping, preserve a generous margin near drops and treat every stream according to conditions on the day.
