Overview
Inishtrahull (Irish: Inis Trá Tholl – “island of the hollow beach”) lies about ten kilometres north‑east of Malin Head, making it the most northerly point of land in the Republic of Ireland. The island covers roughly 34 ha (0.34 km² or 84 acres) and is a flat, windswept plateau edged by sheer cliffs and rocky pinnacles. Its surface is a rare exposure of Inishtrahull Gneiss, a Paleoproterozoic metamorphic rock dated at 1.7 billion years – the oldest known on the Irish islands. Designated a Special Area of Conservation (SAC) and a Special Protection Area (SPA), the island is an Important Bird Area and a sanctuary for seals, sharks and other marine life.
History / Background
- Early settlement – A small community existed from the early 19th century. Census records show 40 residents in 1881, rising to about 80 by 1911. The island supported a school, a graveyard and a handful of stone cottages clustered on the central plateau.
- Evacuation – Illegal foreign trawling in the 1920s devastated the local fish stock. Dáil debates of 1929‑30 record the forced evacuation of the remaining six families in 1929. After that only lighthouse keepers remained.
- Lighthouse chronology
- East‑end tower – First lit on 17 March 1813, designed by engineer George Halpin senior. It stood 12.8 m tall with a focal plane of 10.5 m and was upgraded several times, receiving a first‑order dioptric apparatus in 1864.
- Fog‑signal station – Added at the west end in 1905, creating a second light complex.
- West‑end tower – In 1952 the Commissioners of Irish Lights approved a replacement. A concrete tower, 23 m high with a 2 m internal diameter, was erected in 1956‑58 on the west side.
- Automation – The station was automated in March 1987; the last keepers left on 30 April 1987. The east‑end tower was demolished the following summer, leaving only its stone foundations.
- Solar power – The west tower was converted to solar power in 2000.
What to See & Do
| Feature | Details |
|---|---|
| Inishtrahull Lighthouse (west) | 23 m concrete tower; light at 59 m above sea level; flashes white (three flashes every 15 seconds, often reported as a 30‑second cycle) with a range of 19 nm; solar‑powered since 2000. |
| Ruins of the east‑end lighthouse | Stone foundations and a collapsed lantern, a poignant reminder of early 19th‑century engineering. |
| Historic village remains | Remnants of stone walls, the schoolmaster’s house, a small graveyard and cottage foundations that hint at life before 1929. |
| Geology | Walk the plateau to view the Inishtrahull Gneiss, linking the island to the Rhinns complex of Islay and Colonsay. |
| Wildlife | Designated Important Bird Area – breeding gannets, puffins, razorbills; wintering barnacle geese; grey seals haul out on the rocks; summer brings basking sharks and other cetaceans in the surrounding 90‑metre‑deep tidal sound. |
| Geocaching | Two official caches invite a modern treasure‑hunt for the tech‑savvy explorer (details on Geocaching.com). |
Arranging a Visit
- No regular ferry service – the island can only be reached by charter boat. Operators such as Inishowen Boating run trips from Bunagee Pier.
- Seasonal operation – boats operate from mid‑March to September; trips are weather‑dependent.
- Cost and capacity – the typical charge is around €15 per person, with a maximum of 12 passengers per outing.
- Booking – advance reservation is recommended; confirm the sailing on the day as conditions can change.
- Leave No Trace – all rubbish must be taken back to the mainland.
Conservation and Wildlife
Inishtrahull’s designation as a Special Area of Conservation (SAC) and a Special Protection Area (SPA) reflects its importance for both marine and avian life. The island supports breeding colonies of gannets, puffins and razorbills between May and July, making it a prime spot for bird‑watchers. Grey seals regularly haul out on the western rocks during the summer months, and the deep surrounding sound occasionally brings basking sharks. The island’s geology – the ancient Inishtrahull Gneiss – is of scientific interest, linking the rock formation to the Rhinns complex of nearby Scottish islands.
Practical Information
Getting There
(see Arranging a Visit above)
Landing Restrictions
- During the seabird breeding season (May–July) landing is restricted to protect nesting birds. Boat crews will advise visitors on safe landing points.
Visitor Tips
- Dress for wind and rain; the island is exposed and treeless.
- Bring binoculars for bird‑watching and a camera for the lighthouse’s dramatic dusk sweeps.
- Sturdy walking shoes are advisable for the rocky terrain and low‑lying plateau.
- Check tide tables; the surrounding sound reaches depths of 90 m and can affect landing conditions.
- No public facilities (toilets, water) are available – bring enough water and a packed lunch.
- Dogs are permitted on a leash, especially during the bird‑breeding season.
- Photographers will find the golden hour just before sunset offers striking light on the lighthouse and cliffs.
Seasonal Highlights
- May‑July: Peak breeding season for gannets, puffins and razorbills – best for bird‑watchers but stricter landing rules apply.
- June‑August: Grey seals frequently haul out on the western rocks; occasional sightings of basking sharks in the deeper sound.
- September: The island is quieter, offering a more solitary experience while still providing good chances to see late‑summer seabirds.
