Overview
Blacksod Bay (Irish: An Fód Dubh) is a broad inlet of the Atlantic Ocean on the Erris coast of north County Mayo. The bay stretches roughly 8 km wide at its mouth and is bounded by the flat sand‑dunes of the Mullet Peninsula to the west and the parish of Kiltane to the east. Its many tiny islets, granite‑rich substrate and calm, sheltered waters make it a safe anchorage and a natural showcase for the Wild Atlantic Way. From the harbour you can see the silhouette of Achill Island to the south, while the distant peaks of the Mullet Peninsula frame the horizon.
History
The most iconic feature of the bay is Blacksod Lighthouse, a two‑storey square tower built from locally quarried granite in 1864 (some sources cite 1862). The lighthouse’s white lantern provided the crucial weather report on the night of 3 June 1944; the forecast of a Force 6 wind and falling barometer prompted Allied commanders to postpone the D‑Day invasion by one day, arguably saving thousands of lives. The Sweeney family, who lived in the lighthouse, were later recognised for their role in the operation.
During the Spanish Armada’s disastrous 1588 campaign, the captain of La Rata sought shelter in Blacksod Bay before being forced back to sea. A few days later, other Armada ships used the bay as a temporary haven, and the local Doona Castle (Fahy Castle) became a makeshift base for the Spanish crew.
The 19th‑century Tuke Fund, set up by English Quaker James Tuke, helped many famine‑stricken families emigrate from Blacksod. A memorial garden near the lighthouse commemorates those who left on steamers between 1882 and 1884.
Three other lights punctuate the coastline: Blackrock Lighthouse on the remote Blackrock Island (12 mi west), Eagle Island Lighthouse on the north‑west tip of the Mullet Peninsula, and the historic 18th‑century canal that links Blacksod Bay to Broadhaven Bay via Belmullet.
What to See & Do
- Blacksod Lighthouse tours – Guided 30‑minute tours run Monday to Friday and on weekends during the summer season. Visitors can explore the keeper’s former bedroom, view wartime artefacts and learn about the D‑Day forecast. Tours must be pre‑booked (24 h notice) via the lighthouse website. The lighthouse itself is not generally open to the public; only tour groups may enter.
- Blackrock Lighthouse – Ireland’s most westerly lighthouse; access is only by helicopter, but the helipad on the island is a point of interest for aviation enthusiasts.
- Inishkea Islands – From May to September, Belmullet Boat Charters run day trips to Inishkea South and North. The islands boast beehive huts from the early medieval period, abandoned cottages and a poignant memorial to a 1930s fishing tragedy.

- Deirbhle’s Twist – A stone circle of 22 granite stepping stones created by artist Michael Bulfin in 1993. The sculpture overlooks the bay and is a striking photo spot.
- Saint Deirbhle’s Heritage Centre (Belmullet, ~3 km from the bay) – Exhibits on the 6th‑century saint, local folklore and archaeological finds, presented in Irish and English.
- Boat trips from Blacksod Harbour – The working harbour provides a launch point for ferries to Inishkea South and for scenic cruises that showcase the bay’s islands and sand‑dune headlands.
Walking & Cycling
The Claggan Mountain Coastal Trail is a short, accessible loop that skirts the eastern shore of the bay. For a longer walk, the Gubastuckaun headland offers dramatic cliff‑top views over Broadhaven Bay and excellent seabird spotting. The Glenlara car‑park near Erris Head is a popular base for hunting Merlin and Stonechat during spring, and for spotting Twite and Chough year‑round (see BirdWatch Ireland’s North Mayo guide). All routes are suitable for cyclists, though some sections are sandy and may require a sturdy bike.
