Overview
The Observer once ranked Ballymastocker second on a list of the world’s most beautiful beaches, and the view that earned it – a mile and a half of pale gold sand curving along Lough Swilly – is best had before you reach the sand at all, from the pull-in on the R268 above. Locally the beach is just Portsalon, after the village at its northern end. It sits on the eastern side of the Fanad Peninsula in County Donegal, facing east across the lough to the Inishowen Peninsula, sheltered from the prevailing westerlies by the Knockalla Hills behind.
One honest note up front: the bay lost its Blue Flag for the 2026 season after water quality slipped from ‘Excellent’ to ‘Good’. Donegal County Council is preparing a fresh application for 2027. The sand and the setting are unchanged; it’s the paperwork that lapsed.
The viewpoint and approach
If you do one thing here, stop at the R268 viewpoint before you go down. Coming from the south the road climbs the slope of Croaghaun and the whole crescent opens below you in one go – dunes, sand and the deep blue of Lough Swilly. It faces east, so it’s a sunrise and morning spot rather than a sunset one; the low light rakes across the sand. There’s a marked lay-by to pull into, which matters, because the temptation to stop on the bend is real and the drop is steep.
On the beach
The sand is wide and flat, good for walking, kite-flying and – at low tide – rock pools and tidal shelves that keep children busy for an hour. The water is calm by Donegal standards thanks to the sheltered aspect, which makes it popular for swimming and paddleboarding; Eco Atlantic Adventures runs sea-kayak tours from the area, exploring the caves and cliffs up towards Knockalla Fort.
In summer 2021 Taylor Swift posted an Instagram photo of the bay’s wooden footbridge, and a wave of visitors came to walk the same stretch. For the beach at its quietest, come early or on a weekday. In winter it turns raw and dramatic, and largely yours.
Nature and tides
Ballymastocker sits within a designated Natural Heritage Area that protects the dune system and the intertidal flats. Seals haul out on the outer rocks, and the rock pools hold crabs, small fish and the odd jellyfish in warm weather. The tidal range is wide: low tide gives the biggest walking area and the best rock-pooling, high tide pushes the water close and narrows the strand. Because the beach faces east, an easterly coming across Lough Swilly can chill a fine day quickly, so bring a layer even in July.
Practical information
- Parking – Two car parks. The southern one, by the main entrance, is free and has toilets, picnic benches and seasonal food. A pay-and-display sits up by the R268 viewpoint. Both fill by midday on sunny summer weekends.
- Swimming and safety – Lifeguards operate June to September, 12pm–6.30pm. Swim between the red and yellow flags when they’re on duty. The water is cold year-round and conditions shift with wind and tide.
- Dogs – Dogs are allowed but must be kept on a lead, and owners are expected to clean up after them.
- Facilities – Free toilets at the southern car park. A café, bar and shop sit by the stone pier in Portsalon village, a short walk north.
- Moorings – Free moorings for small dinghies and pleasure craft, with safe anchorage in the deeper water mid-bay.
Nearby
Ballymastocker is on the Wild Atlantic Way, so it strings together with the rest of Fanad. Portsalon Golf Club runs an 18-hole links right at the northern end, its closing holes over the bay. Fifteen minutes north brings the Great Pollet Sea Arch; twenty minutes gets you to Fanad Head Lighthouse, guiding ships since 1817. The harbour village of Rathmullan is twenty minutes south for seafood and a pint, and Glenveagh National Park is about twenty-five minutes inland.
Where to stay
Portsalon village has self-catering cottages and guesthouses within walking distance of the pier, and the slopes of the Knockalla Mountains hold caravan and camping sites – some with glamping cabins – that look straight over the bay. Book ahead for July and August, when demand along this coast peaks.
Do the R268 viewpoint first, before you’re down on the sand – the beach means more seen whole from above.
