Slí Cholmcille – St Colmcille’s Way – is an ambitious, breathtaking trail of adventure and self discovery.
The full ambition for the Slí envisions a trail of continuous walking extending some 460km, linking the main Columban heritage sites across Donegal, Northern Ireland and western Scotland all the way to the Scottish island of Iona.
The illustrated map highlights the current core routes, marked in red, stretching across Donegal’s ancient landscape.
This initial phase of the Slí begins in Glencolmcille in south Donegal and travels north and east through significant heritage sites, reaching Gartan, the place recognised as the birthplace of Colmcille.
Extension spurs and future routes are marked in grey dotted lines.
This Slí route offers a series of one-day hikes that combine to complete a fulfilling challenge based on the paths and places of St Colmcille – one of Ireland’s most important early Christian Saints.
The trail is accessible to anyone at any time via our maps, but we also host guided walks during the year.

Walk in the spirit of St Colmcille/Columba
St Colmcille, also known as St Columba, is one of the most revered saints in Irish history.
Born in 521 AD in what is now County Donegal, Ireland, he is celebrated for his profound influence on the religious, cultural, and social landscape of Ireland and Scotland.
Alongside St Patrick and St Brigid, Colmcille is one of Ireland’s three patron saints.
His legacy endures through the monasteries he founded, the cultural and religious traditions he established, and the values he espoused.
