The best traffic-free bike rides around Ards Forest

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 dominates the landscape of West Donegal with its 751-meter-high quartzite pyramid. From the road around Dunlewy and Gweedore, you'll see the mountain constantly change shape: first broad and massive, then sharp and almost symmetrical as you get closer. The light grey scree slopes and the open moorland valleys around it give Errigal an almost alpine appearance, unique to this region. For cyclists, Errigal is primarily a visual anchor point: a constant presence above the Derryveagh Mountains, visible for miles ahead and behind you. In clear weather, the summit reflects in Dunlewy Lough, making this one of Donegal's most impressive panoramas. The surroundings are open, rugged, and vast — precisely the kind of landscape that makes a ride here so special.

From this point on the R251 you have the most impressive and unobstructed view of the southwestern flank of Mount Errigal. The mountain rises here almost vertically from the peatland landscape, with the glittering white quartzite scree slopes often mistaken for snow. It is at this moment that you truly realise the immense scale of the mountain; the conical shape dominates the entire horizon here, forming a sharp contrast with the dark, surrounding "boglands".

Dunlewey lies at the foot of Mount Errigal, on the shore of the tranquil Dunlewey Lough. The village forms one of West Donegal’s most characteristic spots: a combination of rugged mountains, open water and the iconic ruin of the old church overlooking the lake. The area breathes Gaeltacht culture and silence — broad vistas, peat fields and the sharp silhouette of Errigal constantly hanging over the landscape. Dunlewey is a natural hub between the valleys of Gweedore, Glenveagh and the Seven Sisters, and a place where Donegal’s landscape comes together in its most dramatic and photogenic way.

If starting from Dunlewy and heading clockwise, this represents the very last section of the Slí An Earagail long-distance trail. Fittingly, it ends beneath the hulking presence of Errigal, the trail's namesake peak and highest mountain in the county. On this stretch, you're also rewarded with great views of the Poisoned Glen, a spectacular valley associated with legends.

Towering above all else in the Derryveagh Mountains, Errigal is one of Ireland's most photogenic mountains. From this direction, it looks every bit the classic peak, its scree slopes tumbling from an arrowed quartzite summit. The ascent options from this direction are as exciting as its appearance would suggest. The North Ridge is a superb grade one scramble, while the neighbouring Tower Ridge is a steeper, more committing grade three scramble.
