Located in the shelter of Melmore Head, you will find this spectacular beach. With its fine golden sand and crystal-clear, almost turquoise water, Melmore Beach looks non-Irish on sunny days. It is the perfect place where the rugged Atlantic Drive briefly comes to rest. Photo tip: Photograph from the elevated road towards the bay to capture the beach's crescent shape and the water's colour gradations.

Rossguill lies between Fanad to the east and Horn Head to the west, a narrow peninsula where heather, dunes, and ocean alternate. The coastline is open and slightly curved, with calm beaches and low ridges that constantly offer new views of Mulroy Bay and the Atlantic side. The roads run close to the water and through small, scattered settlements, making the landscape feel both vast and intimate. It is an area defined primarily by light, wind, and the open space of North Donegal.

From this high point, you look out over Tranarossan Bay, a quiet, semi-circular inlet on the north coast of Rosguill. The view combines clear turquoise water, light sandy beaches, and the rugged rock heads that are so typical of this part of the Wild Atlantic Way. In good light, you can see how the bay looks almost Caribbean, while the rugged hills behind preserve the pure Donegal character.

Rosguill Panorama: The Untamed North Coast. Photo tip: Use the depth of the coastline to give scale to your photo. The contrasts between the green heath, the dark rocks, and the changing light on the water make this a top location for landscape photography. From this elevated point, you look down on the rugged beauty of Dooey Beach, a vast stretch of golden sand constantly shaped by the powerful surf of the Atlantic Ocean. No tourist crowds, just wind, water, and the rhythm of the waves. The panorama is a 360-degree spectacle: the ocean stretches to the horizon, while the rugged coastline of the bay is framed by deep blue inlets and white foam crests. For cyclists on the Atlantic Drive, this is a challenging but rewarding segment — the narrow road follows the cliff edge, giving an intense sense of freedom.

Mount Errigal (751 m) is the highest mountain in Donegal and one of Ireland's most iconic peaks. The mountain is immediately striking with its sharp, pyramid-shaped silhouette and its quartz summit that shines almost white in sunlight. Errigal stands apart from the surrounding hills, giving it a dominant presence from all directions — especially when driving inland from Dungloe, Doochary, or Dunlewey.

From this quiet footpath, the view opens beautifully across Dunfanaghy, its coastline and the surrounding Donegal hills. The village, whose name comes from the Irish Dún Fionnachaidh meaning “fort of the fair field,” has long been shaped by the Atlantic and the dramatic landscape around Horn Head.

"Where the mountains rise to the oft-changing skies, And the castle stands stately and gray; Where the still lake still lies, beneath that wild, rugged hill, In the vale of lovely Glenveagh..." By: Herbert W.K. Sterritt

The lookout is rather unspectacular. The magnificent coastal landscape is worth seeing.
