Overview
The Old Head peninsula does something useful: it takes the brunt of the Atlantic, so this beach stays swimmable on days when the rest of Mayo’s coast is churned up. Add a full view of Croagh Patrick straight across the water, and you have one of the more dependable swimming beaches in the county. It sits on the eastern edge of Clew Bay, 3.5 km east of Louisburgh and about 20 km west of Westport on the Wild Atlantic Way, a long sweep of golden sand backed by Atlantic oak woodland and stretching to around 1.5 km at low tide. It carries Blue Flag status – it flew the flag in 2024, and reportedly since – for water quality, safety and facilities.
Why visit
The peninsula works as a natural windbreak, giving the beach a sheltered micro-climate that keeps the water calm when the open coast is choppy, which is what makes it such a steady bet for families. Beyond the swimming there’s a wooden pier with a Finnish-style sauna, quiet water for paddling, and, 200 metres back from the sand, a protected oak wood that meets the sea – a habitat found in only a handful of Irish sites.
What to see and do
- Swimming and rock pools – the stretch nearest the car park is shallow and sheltered, good for children, with a small freshwater stream crossing the sand and rocky outcrops at either end that form natural pools.
- Pier sauna and coffee – at the western end the wooden pier doubles as a spot for pier-jumping and angling, and holds a Finnish-style sauna plus a coffee trailer serving Lavazza, cold drinks and snacks. Sauna sessions run seasonally and are booked online.
- Paddleboarding and kayaking – the calm water suits SUP and sea kayaking, and it’s part of Mayo’s Blueway. Summer SUP & Kayak runs rentals and lessons from the main car park, from the May bank holiday through September; book ahead in peak season.
- Coves toward Kilsallagh – walk east toward Kilsallagh and Falduff for quieter sand and some interesting coastal geology. The tide rarely covers the whole shoreline, and at low water the beach runs to well over 2 km if you take in the adjoining Kilsallagh Bay.
Walking and wildlife
The Old Head Wood Trail is a gentle 2 km loop from the car park, threading the Atlantic oak wood before opening onto a secluded cove with the beach and Croagh Patrick behind it. You can carry on along the coast toward the Kilsallagh and Falduff headlands for a longer walk with cliff-top views and seabirds.
The wood holds Special Area of Conservation status for its rare Atlantic oak habitat – one of very few Irish places where it grows right up to the coast. The canopy supports tits, spotted flycatchers and chiffchaffs, while the shore draws cormorants, shags, waders, gulls and terns, and seals turn up offshore now and then. Stay on the marked paths to protect the ground.
Practical information
Getting there and parking
From Louisburgh, follow the main road east for 3.5 km to the signed turn, then a narrow lane down to a large, shaded car park. Parking is free and roomy enough for busy days, but there’s a height barrier of about 2.1 metres across the entrance, so campervans and vehicles with roof-boxes can’t get in. The limited roadside spaces by the pier are kept for emergency vehicles.
Facilities and access
Wheelchair-accessible toilets are in the car park, and firm sand with level access ramps make the beach manageable for wheelchairs, buggies and mobility aids. Picnic benches line the entrance. The sauna and coffee trailer run seasonally from late May to early September, with times posted on site. Dogs are welcome on a lead – clean up after them – but during the summer bathing season, roughly midday to 6.30pm, they’re kept off the Blue Flag stretch.
Safety and lifeguards
Lifeguards cover the bathing season from 30 May to 30 August: weekends only through May and June, daily across July and August, and sometimes into the first weekend of September. Daily hours are posted near the car park. The water is usually calm, but watch for jellyfish in summer and steer clear of the eroding rock outcrops near the middle of the beach.
Nearby stays and attractions
Louisburgh has B&Bs and self-catering cottages, and a 15 to 20 minute drive to Westport opens up hotels, restaurants and the trailhead for the Great Western Greenway. With more time, the coast road south links to Silver Strand, the Lost Valley and Aasleagh Falls, and Ballycroy National Park is within reach for forest walks and more Atlantic coastline.
Time a falling tide and walk east toward Kilsallagh: the sand keeps going, the crowds don’t, and the rock pools open up along the way.
