Make the Most of Donegal’s Great Outdoors
One of the biggest advantages of visiting Donegal in September is that conditions are still perfect for outdoor adventures.
Walk Among Some of Europe’s Most Spectacular Scenery
Autumn is a fantastic time to lace up your walking boots and discover Donegal’s many trails. From coastal paths overlooking the Atlantic to forest walks and mountain routes, the county has options for every level of walker. Donegal is renowned for its extensive network of walking routes and scenic trails, making it a dream destination for outdoor enthusiasts. The Inishowen Walking Festival takes place from 12th to the 20th of September with guided walks across various locations throughout Inishowen suitable for all ages and abilities.
A must-visit location is Glenveagh National Park, where visitors can enjoy lakeside walks, mountain scenery, native wildlife and the stunning Glenveagh Castle and Gardens. The park remains open throughout the year and is particularly beautiful as the colours of autumn begin to emerge across the landscape.
Discover Donegal’s Signature Wild Atlantic Way Experiences
September’s clear days often bring some of the year’s most spectacular views, making it an ideal time to visit Donegal’s iconic Wild Atlantic Way discovery points.
Stand atop the breathtaking Sliabh Liag Sea Cliffs, among the highest accessible sea cliffs in Europe, marvel at the rugged beauty surrounding Fanad Lighthouse, or journey north to Malin Head, Ireland’s most northerly point. These world-famous landmarks showcase the dramatic scenery that makes Donegal unlike anywhere else in Ireland.
Explore Donegal’s Islands
September also offers ideal conditions for a day trip to one of Donegal’s offshore islands. From Árainn Mhór and Tóraigh to some of the county’s smaller island communities, visitors can experience rich Gaelic culture, spectacular coastal scenery and a slower pace of life that feels a world away from everyday routines.
Celebrate Traditional Music in Ardara
Towards the end of the month, music takes centre stage at The Johnny Doherty Festival, taking place in Ardara from 25th to 27th September. The festival honours one of Ireland’s greatest traditional musicians and sees the town come alive with sessions, concerts and performances celebrating Donegal’s rich musical heritage.
Ardara itself is one of Donegal’s most charming heritage towns and the perfect base from which to explore nearby beaches, mountain passes and coastal drives.
