April 8, 2026, Kilclooney Dolmen

Hidden in the green landscape near Kilclooney, you'll find this spectacular Neolithic portal tomb, one of the most elegant examples of prehistoric architecture in Ireland. The enormous capstone of the largest dolmen balances with astonishing precision on its supporting stones and has overlooked the surrounding fields for over 5,000 years. Directly next to it lies a second, smaller dolmen, making this site a remarkable archaeological ensemble.

This stretch of the Slí An Earagail long-distance trail follows a quiet country lane, providing lovely views of rural Donegal countryside. This is a Gaeltacht (Irish speaking) region of the country where proud traditions and customs are still practised.

A charming townland on Donegal's Atlantic coast, An Bun Beag (often Anglicised to Bunbeg) has much to offer the walker. A stroll to the beach reveals the enchanting Bád Eddie shipwreck, one of the region's iconic sights. It forms the foreground to another icon, the distant Errigal, one of Ireland's most recognisable mountains. The village and neighbouring Doirí Beaga (Derrybeg) are home to a few accommodation options and places to eat and drink.

Superbly situated at the foot of mighty Errigal in the fabled Poisoned Glen, Dunlewy has much to offer the intrepid hiker. There's the Lakeside Centre at Dunlewy Lough for meals, information and boat trips on the lake. A hike up to the spectacular twin summits of Errigal is a must for keen hillwalkers. The village has a number of accommodation options, including the Errigal Hostel.

Ardara showcases rural Ireland at its best. The village is beautifully maintained, boasts plenty of traditional pubs, and there are a handful of restaurants serving good food.

A beautiful view of the Irish Fujijama. Near the hotel on the road there are a few archaic round stone posts which, together with the water, provide a beautiful foreground.
