Baily Lighthouse – Howth Head

Overview

You can’t visit Baily Lighthouse – it’s private property, gated off about 100 metres short of the tower – so treat it as the turning point of a cliff walk rather than a destination in itself. It stands on the southern tip of Howth Head above Dublin Bay: a squat granite tower, 13 metres (43 ft) high, with a white lantern and a red rail, its light sitting 41 metres above the sea. It’s still an active beacon, flashing white every 15 seconds with a range of 18 nautical miles. If you’ve an hour and want the single best view, skip the tower and walk up to the summit car park – the bay opens out from there as far south as Dún Laoghaire, Bray and the north Wicklow coast.

History

The first beacon on this headland was erected in 1667 by Sir Robert Reading, a pioneer of Irish coastal lighting. His original structure was a modest cottage with a square tower housing a coal-fired light. By the early 19th century, the site proved too high and frequently shrouded in fog, prompting the Corporation for Preserving and Improving the Port of Dublin to relocate the light to a lower, more reliable position.

On 17 March 1814, a new granite tower and keeper’s house designed by engineer George Halpin Senior were completed at Little Baily (Duncriffan). The tower originally displayed a fixed white catoptric light produced by 24 Argand oil lamps. Over the following decades, the lighthouse evolved alongside maritime technology.

Technological evolution

• 1853 – Fog bell: Installed after the tragic loss of the paddle steamer Queen Victoria in February of that year.
• 1865 – First-order dioptric lens: Greatly extended the light’s range and visibility.
• 1865-1870s – Gas experiments: John R. Wigham’s gas-burning system was trialled here, paving the way for similar conversions at other Irish lighthouses.
• 1871-1926 – Fog signals: An air-trumpet foghorn arrived in 1871, later replaced by a siren and then a G-type diaphone. The original bell remained as a standby until 1890.
• 1902 – Flashing characteristic: The light began flashing once every 30 seconds.
• 1908 – Paraffin illumination: Gas mantles gave way to an incandescent vapour-paraffin burner.
• 1972 – Electrification: A 1,500-watt electric lamp in a rotating AGA lens produced a flash every 20 seconds, later altered to the present 15-second interval.
• 1996-1997 – Automation: Baily became the last lighthouse in Ireland to be fully automated; the final keeper left on 24 March 1997. An attendant now resides in the former principal keeper’s house to address technical issues.

Museum and modern use

A small museum was set up in the reconditioned keeper’s buildings in 2000, with artefacts, panels and photographs on the lighthouse and its keepers. Don’t build a visit around it, though: it doesn’t keep regular hours, and access is by arrangement for staff, former staff, their families and small interest groups rather than casual callers. Part of the old buildings has since been taken over as offices for the emergency-management software firm D4H. The lighthouse’s original 1902 optic, its pedestal and rotation machine are on public display elsewhere – at the National Maritime Museum in Dún Laoghaire.

What to See & Do

While you cannot enter the tower itself, the surrounding landscape offers plenty to explore. The lighthouse sits at the heart of Howth’s coastal walking network, making it a natural focal point for several marked trails.

• The Howth Cliff Walk: This 12 km full-loop route passes directly by the lighthouse and is suitable for walkers of most fitness levels. It connects the harbour, the summit, and the eastern cliffs, offering uninterrupted views of the coastline.
• The Tramline Loop: A shorter 7 km circuit that follows the old Dublin–Howth electric tramway. The path climbs steadily through woodland and grassland before opening up to reveal the lighthouse just as the former tram route transitions into a footpath.
• Panoramic Views: From the summit car-park, the vista stretches across Dublin Bay to the city skyline, Ireland’s Eye, and Lambay Island. On clear days, the Wicklow Mountains form a dramatic backdrop to the east.

The keeper’s museum in the reconditioned buildings isn’t open on set days – access is by prior arrangement for interest groups, so don’t turn up expecting to get in. If you want to see the lighthouse’s old workings, the original 1902 optic is on display at the National Maritime Museum in Dún Laoghaire instead.

Wildlife & Birdwatching

The steep cliffs around Baily Lighthouse provide an important habitat for seabirds and coastal wildlife. Spring and early summer are particularly rewarding for birdwatchers, as gulls, razorbills, and occasional terns return to nest on the rock faces. In recent years, the area has made headlines for the return of the red-billed chough (Pyrrhocorax pyrrhocorax), a species that had not been recorded on Howth Head since 1982. Binoculars are highly recommended for spotting these birds against the Atlantic backdrop.

Getting There & Transport

Baily Lighthouse is easily reached from Dublin city centre without a car. The DART from Connolly, Tara Street, or Pearse stations reaches Howth DART Station in roughly 25 minutes. From the station, follow the green coastal signs toward the Howth Summit car-park or join any of the marked walking loops.

Dublin City Bus routes #31 (terminating at Howth Harbour) and #31b (terminating at the Summit) run every 15–20 minutes, taking about 30–35 minutes from the city centre. Both buses drop you within walking distance of the trailheads.

For drivers, a small free car-park at the Howth Summit fills quickly during peak summer weekends. A pay-and-display area at Balscadden Bay offers an alternative, with a short, clearly signposted walk up to the lighthouse trail.

Visiting Tips

• Footwear & Weather: The cliff paths are uneven and can become slippery when wet. Sturdy walking shoes with good grip are essential, and a waterproof layer is wise regardless of the season.
• Dogs: Leashed dogs are welcome on the trails, but keep them under close control near the cliff edges where the drop is steep and sudden.
• Photography: Dawn and dusk offer the best light, casting warm tones across the granite stonework. The lighthouse’s 15-second flash cycle makes it straightforward to capture long-exposure shots of the beam cutting through coastal mist. If it looks familiar, the lighthouse featured in the Apple TV+ series Bad Sisters and in the book Accidentally Wes Anderson.

Nearby attractions

A short walk from the lighthouse leads to Aideen’s Grave, a legendary Bronze Age dolmen perched on the cliffs. Further down the coast, Howth village offers fresh seafood, independent shops, and the historic Howth Castle grounds, making it easy to extend a coastal walk into a full day trip.

Practical Information

Give it a clear day and allow a couple of hours: walk out to the lighthouse and back along the cliffs, take the view from the summit, and finish with coffee or a plate of seafood down in Howth village before the DART home.
