With 20,000 inhabitants, Letterkenny is the most populous town in Donegal. While not exactly a charming town, it offers a convenient base for exploring the region and is certainly worth a visit for its lively atmosphere, particularly the pubs. The town also has an informative museum about the region's history, the Donegal County Museum.

Nestled amidst the typical Irish landscape, this charming town, founded in the 17th century, owes its prosperity to linen production and tanneries, whose tall grey stone buildings still stand. Especially in the evening, at sunset, the quay is a pleasant place, where the memory of the once-rich warehouses and the ladies' promenade is preserved.

This viewpoint along the spectacular coastal road offers a more intimate perspective on Ballymastocker Strand. As you cycle or walk down (or up) the flanks of the Knockalla Mountains, this is the perfect spot to truly experience the scale of this enormous sandy beach. You are looking straight across the Magherawarden dunes towards the distant contours of the Fanad lighthouse. The colours of the bay – from deep blue to crystal clear turquoise – are beautifully showcased at this height against the backdrop of white sand.

The pier at Portsalon is one of the most photogenic spots in Donegal. From this historic stone quay, you have an unforgettable view of the famous golden arch of Ballymastocker Bay, once named the second most beautiful beach in the world by The Observer. The pier is the vibrant heart of the village; you'll often see local fishing boats docking here and in the summer it's a popular spot for a refreshing dip in the clear waters of Lough Swilly.

The Visitor Centre at Fanad Head Lighthouse is the starting point for one of the most iconic locations along the Wild Atlantic Way. From here, you can walk to the lighthouse and get an impressive view of the cliffs and the Atlantic Ocean. The centre provides information about the history of the lighthouse, shipping, and the surrounding area. The combination of rugged coast, clear light, and the sound of the ocean makes this an ideal place to take a break, take photos, or visit the lighthouse before continuing your drive towards Ballyhiernan Bay or Mulroy Bay.

In my opinion, this is one of the less beautiful stretches of road you can encounter here. The asphalt is fine, the road is flat and straight. The view is nil, or was I spoiled on the Wild Atlantic Way (S=>N)?

This official Discovery Point on the Wild Atlantic Way offers one of the most serene views in North Donegal. From this point, you look out over the sheltered waters of Mulroy Bay and the small, low-lying Island Roy (Oileán Ruaidh). The island is unique as it is connected to the mainland by a narrow causeway, which is sometimes submerged at high tide. On a clear day, the view stretches to the sand dunes of Rosapenna and the distant peaks of the Derryveagh Mountains, including the striking Muckish Mountain.
