Thirty-one beaches sit along a coast that runs from Donegal Bay in the south to the top of Inishowen, so this is not a list to work through from one base.
Rossnowlagh leads it, three kilometres of Blue Flag sand facing straight into Donegal Bay, with two long-running surf schools working the strand. Bundoran Main Beach is 500 metres of lifeguarded sand off the Main Street, with The Peak reef break a short walk away. On Fanad, Ballymastocker Bay curves a mile and a half along Lough Swilly, and the view most people photograph is from the pull-in on the R268 above it. Carrickfinn is in the Gaeltacht beside Donegal Airport, the runway running along the shore. Killahoey starts at the edge of Dunfanaghy village under Horn Head, with the ribs of the trawler Dinas showing on the sand at low tide.
Several of these are for walking rather than swimming. Five Fingers Strand on Inishowen is backed by dunes up to 30 metres and the water is dangerous; Maghera’s caves under Slievetooey open only at low tide, with a rip current and no lifeguard; at Magheraclogher, where Bád Eddie rusts on the sand, the channel drops off fast. Lifeguards work the main Blue Flag beaches in summer only.
Three kilometres of Blue Flag sand facing Donegal Bay, gentle enough for a first surf lesson in summer and serious in winter.
A mile and a half of pale gold sand curving along Lough Swilly on Fanad, once ranked the world's second best beach.
Five hundred metres of lifeguarded sand straight off the Main Street, with a bookable beach wheelchair and The Peak reef break nearby.
White Gaeltacht sand and machair grassland beside Donegal Airport, where the runway runs along the shore and planes come in low over the dunes.
A wide Blue Flag arc on Inishowen with a shallow estuary for paddling, Atlantic surf beyond it and village pubs a short walk away.

Rossnowlagh, donegal
Rossnowlagh's 3 km Blue Flag strand faces straight into Donegal Bay, so it works for beginners on a summer's day and heaves into 7 m swells in winter. Two long-running surf schools work the beach, and a Franciscan friary above it holds a small county museum.
Fanad Peninsula, donegal
Ballymastocker Bay – Portsalon Beach on the Fanad Peninsula – is a mile and a half of pale gold sand curving along Lough Swilly, the beach the Observer once ranked second in the world. The view is best from the pull-in on the R268 above. It lost its Blue Flag for 2026 on a water-quality dip, with the council aiming to win it back for 2027.
Bundoran, donegal
Bundoran Main Beach runs 500 metres of sand right off the Main Street, lifeguarded in summer and with a beach wheelchair you can book. The Peak, a fast left-hand reef break a short walk away, is why the town calls itself Ireland's surf capital.
Carrickfinn, donegal
Carrickfinn is a Blue Flag beach of white sand and machair grassland in the Donegal Gaeltacht, right beside Donegal Airport. The single runway runs along the shore, so you can watch planes come in low over the dunes while you walk.
donegal
Culdaff Beach is a wide arc of golden sand on the Inishowen Peninsula, with a Blue Flag for water quality. The River Culdaff estuary creates a shallow paddling area, while the Atlantic swell brings consistent surf. Lifeguards patrol in summer, and the village of Culdaff has pubs and shops a short walk away.
Dunfanaghy, donegal
A small village on Sheephaven Bay with three good beaches on its doorstep, the Horn Head loop drive for the views, and a community-run workhouse that tells Donegal's famine story through the life of one child who survived it.
Fintra Beach, donegal
Fintra is one of Donegal’s widest, most sheltered strands – a kilometre of sand backed by dunes, 3 km west of Killybegs. The calm lagoon at the far end is the pick for families; the small car park at the top of a steep, height-barriered lane is the catch.
Inishowen Peninsula, donegal
Five Fingers Strand on the Inishowen Peninsula is backed by dunes up to 30 metres high, among the tallest in Europe, with the five sea-stacks that name it rising offshore. The sand is spectacular and the water is dangerous, so it's a beach for walking, photography and low-tide rock pools rather than swimming.
donegal
Gweedore is the largest Irish-speaking district in Ireland, where Irish is genuinely the language of daily life. Mount Errigal rises behind a coast of Blue Flag beaches and the mist-filled Poisoned Glen, and the trad sessions at pubs like Leo's Tavern are the real thing rather than a show for visitors.
Dunfanaghy, donegal
Killahoey runs from the edge of Dunfanaghy village along Sheephaven Bay – just over a kilometre of sand under Horn Head, with Blue Flag water and lifeguards from June to mid-September. At low tide the ribs of the steam trawler Dinas, wrecked in 1937, show on the sand.
Urris, donegal
Lenan Beach is a wide, flat run of golden sand backed by the Urris Hills, with a free car park, a few picnic tables and little else. It's also the start of the Lenan Loop and the longer Urris Lakes Loop, two of the best short hillwalks on Inishowen, and the ruin of Lenan Head Fort crowns the headland above the far end.
Ardara, donegal
Maghera's white strand sits under the cliffs of Slievetooey on Donegal's Slieve League peninsula, with more than 20 caves, arches and tunnels cut into the rock and reachable only at low tide. The setting is the draw, not a swim, there's a fierce rip current and no lifeguard. Park at the farm car park (€3–€5 cash) or walk over from Assaranca Waterfall.
Bunbeg, donegal
Magheraclogher, better known as Bunbeg Beach, is a wide sweep of Gweedore sand with Mount Errigal rising behind it. Its landmark is Bád Eddie, a French-built fishing boat driven ashore here in the early 1970s and left to rust into Donegal's most photographed wreck. Fine for paddling and photos, but not for swimming: the channel drops off fast.
Maghery, donegal
Maghery sits on a bay in the Rosses, west Donegal, where a short white-sand strand meets cliffs, sea arches and a scatter of islands in Dungloe Bay. Its built heritage runs to the Georgian Termon House of about 1770, a Napoleonic signal tower with an 'Éire' sign, and the Red House left from the old kelp trade, with sea-kayaking and climbing run from the pier and the community hub at the strand.
Malin Beg, donegal
A flight of 174 steps drops from the clifftop car park to Silver Strand, a horseshoe of pale sand and clear water at the western end of the Slieve League Peninsula. This Gaeltacht corner past Glencolmcille stays quiet outside high summer, and the water is clear enough that divers come for it.
Marble Hill Beach, donegal
Marble Hill is a sheltered 1.3 km Blue Flag beach at the western end of Sheephaven Bay, five minutes from Dunfanaghy. Two headlands keep the water calmer than the open Atlantic beaches nearby, and lifeguards patrol in July and August. In 1942 an RAF bomber landed on the sand and took off again the next morning.
Rosguill Peninsula, donegal
Melmore Head sits at the northern tip of the Rosguill Peninsula, where a beach and the much-photographed Murder Hole are reached by a walk across private farmland from a €5 car park. The headland carries the ruins of a Napoleonic watch tower and long views to Fanad Head and Tory Island. Strong currents make Murder Hole dangerous for swimming, so come for the walk and the views, not a dip.
Dunfanaghy, donegal
Murder Hole Beach is a tidal cove on the Rosguill Peninsula, reached by a steep 20 to 25 minute walk from a car park that costs €5 cash and shuts at 8pm. Come at low tide: the two beaches merge into one, a sandbar opens to Rough Island, and the sea cave in the eastern cliffs becomes reachable. Do not swim – the rip currents here have killed.
Narin, donegal
Narin Strand runs nearly two kilometres along Gweebarra Bay, sheltered by Dunmore Head and backed by protected dunes. At low tide a sandbank opens for the walk out to Inishkeel Island, where two early-Christian churches and a holy well stand among the ruins. Brendan Behan swam here in 1961; the swimming is still the draw.
Pollan Bay, donegal
Pollan Bay is a long sandy beach on the north-west corner of Inishowen, near Ballyliffin, looking out to Glashedy Island and Malin Head. Free parking, a playground on the sand and a coffee van make it easy with children – but swim only at the southern end, where it's safe, as there are no lifeguards. From the car park it's about 5km along the dunes to the ruined Carrickabraghy Castle.
Rosguill Peninsula, donegal
Two steep hills fold in around Tra na Rossan, and photographers come for the low light that pours through the gap between them. It's remote and unlifeguarded, and since 2026 the direct path from the car park has been gated – but the strand and the Lutyens-designed hostel above it still reward the drive.
Bundoran, donegal
A two-kilometre surf beach running from Bundoran to the Erne estuary, backed by dunes and the Dartry Mountains. Red Bull rated it Ireland's best beginner surf spot in 2016, but strong rip currents and no reliable lifeguard make it one to surf and walk, not swim.
