This is the route as it was meant to be walked. Starting in Ravensdale Forest and finishing in Newcastle under the shadow of Slieve Donard, the 7-day tour covers every stage of the Cooley-to-Mournes journey: the ancient Táin Way ridgeline, the descent into medieval Carlingford, a day to explore the peninsula from its heart, then across the border for Kilbroney Forest, Tollymore, and the full Mourne Way.
Crossing from the Republic of Ireland into Northern Ireland on foot is a genuinely rare experience. Most Irish walking holidays stay in one jurisdiction. Here the border is just a line on a map — the landscape flows seamlessly from the mythical Cooley hills into the granite Mournes, connected by a trail that has been walked for centuries.
Seven days gives you exactly the right amount of time: enough to really inhabit each place, recover properly between stages, and arrive in Newcastle having done something that feels complete.
Begin in the beautiful Ravensdale Forest, climbing through ancient woodland to the open heather moorland of the Cooley Mountains — the first chapter of one of Ireland's great walking journeys.
Follow the ancient droving road of the Táin Way along the spine of the peninsula, crossing Maeve's Gap with sweeping views over the Irish Sea, Carlingford Lough, and the Mournes before descending to Carlingford.
A full day based in Carlingford — looped walks, oysters, King John's Castle, and the medieval streets of one of Ireland's finest villages.
Two days following the Mourne Way through Kilbroney Forest and Tollymore — a Game of Thrones filming location — to Newcastle in the shadow of Slieve Donard, Northern Ireland's highest peak.
This tour suits experienced walkers who enjoy moderate to challenging terrain over multiple days. You should be comfortable walking 15–20 km per day with significant ascent on the Cooley stages — particularly the Lumpers-to-Carlingford ridgeline stage with over 600 metres of climbing. The Mourne Way stages are more moderate: mixed forest paths, river trails, and open countryside. Seven days gives a genuine cross-border mountain experience without the physical demands of the 8-day extension. Ideal for walkers who have done multi-day routes before and want a complete, unhurried Irish adventure.
Arrive in Dundalk, your first base. The town is well connected to Dublin and Belfast by rail and bus — full details in your pre-departure pack. Settle in, explore, and rest before seven days of walking begins tomorrow.
Your opening day takes you through Ravensdale Forest and into the Cooley Mountains. The trail climbs from sheltered woodland to open moorland, with views growing wider with every step. You return to Dundalk for a second night after a rewarding day on the hill.
The most spectacular stage — along the spine of the Cooley Peninsula on the ancient Táin Way. Crossing Maeve's Gap, the views open over Carlingford Lough and the Mourne Mountains. The descent into Carlingford is one of the great arrivals in Irish walking: the medieval village appearing below, the lough glittering beyond.
A day based in Carlingford — choose from the looped walks exploring the lough shore and lower slopes, or simply spend the day in the village: King John's Castle, the medieval lanes, the waterfront, and Carlingford's famous oysters. This is your recovery day before the Mournes.
Today you cross the border into Northern Ireland and begin the Mourne Way. Through Kilbroney Forest, past the foothills of the Mournes, and into the Victorian village of Rostrevor on the southern shore of Carlingford Lough. The border is seamless underfoot — two countries, one trail.
The finest walking day in the Mournes. Through Tollymore Forest Park — ancient woodland, stone bridges, the Shimna River, and the eerie beauty of a Game of Thrones filming location — before emerging in Newcastle under the watchful shadow of Slieve Donard.
A final breakfast with the Mournes as your backdrop. Your pre-departure pack covers public transport options to Dublin (via Newry) and Belfast. We can arrange private transfers if preferred — just let us know.

May and June are our top picks. Long evenings, wildflowers on the Cooley foothills and manageable trail traffic make these months hard to beat. June and early July offer the longest daylight hours, which matter for the longer Mourne Ridge days.
September is arguably the finest month of all. Bracken turns gold, the light is sharp and clear, trails are quieter, and accommodation is easier to book.
July and August are the warmest months but the busiest. Slieve Donard sees significant foot traffic, and accommodation needs to be booked well in advance.
The walking season runs from late spring through to late autumn, typically April to October.
Time your visit with a festival. Many trails host walking festivals throughout the season — see our complete 2026 walking festivals calendar to plan around one.
