Slí Cholmcille
Gleann Cholm Cille, Co. Donegal
Free to visit
Revel in County Donegal’s unspoilt coastal and mountain landscapes on a 65km loop that connects idyllic towns, villages and spectacular scenery along the Wild Atlantic Way.

A moderate trail, Slí Cholmcille is a 65km looped section of the longer 280km Slí Dhún na nGall in stunning southwest Donegal.

This inspiring loop connects the area’s main towns and villages - Glencolmcille, Kilcar, Carrick and Ardara - and passes through swathes of untouched coastal and mountain landscape.

The route consists of tarmac roads, bog roads, and open moorland. It’s worth noting that considerable stretches of the tarmac sections do take place on busy, narrow roads where care and attention is required. Some of the route’s open moorland sections, which are quite isolated, can also be very wet, so appropriate all-weather walking gear is needed.

Over the entire loop, the total aggregate ascent is 1,600m. Walkers will find plenty of overnight accommodation and friendly welcomes across Glencolmcille, Kilcar, Carrick and Ardara.

    Why we like it
    • Highlights on this loop include a stunning valley stretch reaching down to the inlet of Port, and the dramatic valley of Glengesh.
    • The name of the route is derived from that of St Colmcille, one of Ireland’s early Christian saints, who was born in County Donegal and lived for a time in the region. 
    • Glencolmcille, one of the villages this loop connects with, is Donegal’s most westerly village. The surrounding area is rich in prehistoric and early Christian monuments.
