Overview
Sruwaddacon Bay (Irish: Sruth‑Mhada‑Conn, literally “Stream of the Long Hound”) is a tidal estuary that cuts through the Gaeltacht parish of Kilcommon in Erris, County Mayo. Covering roughly 8.4 km², the bay is fed by the Glenamoy and Muingnabo rivers in its north‑westerly‑oriented main channel, while a secondary channel loops around the village of Rossport, drawing water from the Gweedaney stream. The two channels converge into a fast‑flowing mouth that opens into the Atlantic via Broadhaven Bay, another EU‑protected marine area.
The estuary’s shape—long and slender like a greyhound—gives the bay its English name, “Stream of the Long Hound”. Its waters are characterised by exceptionally strong currents, especially in the lower reaches, and a mix of sand, mud, cobble and rock substrates that support a surprisingly diverse marine community.
History & Background
Legend and Song
Local folklore records a tragic 18th‑century love story that ended in the bay’s waters. The ballad Liam Ó Raghallaigh tells of a bride‑to‑be whose fiancé drowned while rowing across the estuary to fetch the priest for their wedding. The mournful verses describe eels, crabs and the “sharp discipline of the salmon” that claimed his life, embedding the bay in the cultural memory of the region.
Archaeology
Archaeological surveys carried out in 2008 for Royal Dutch Shell uncovered a series of remarkable finds beneath the bay’s sediments. Core samples near Aghoose townland revealed hazelnut shells at a depth of 10.7 m, while earlier surface finds include a flint arrowhead (1953), a stone axe‑head (1957) and bog butter in a wooden vessel (1968)—all now housed in the National Museum. These artefacts attest to human activity in the area long before the modern era.
Modern Controversy
The bay has been at the centre of the contentious Corrib gas project. Plans to lay a high‑pressure, raw natural‑gas pipeline across the estuary have prompted a tunnel‑construction proposal by Shell. Local groups such as Pobal Chill Chomáin and Shell to Sea have opposed the scheme for over a decade, citing environmental and cultural concerns.
What to See & Do
Wildlife Watching
Designated as both an EU Special Area of Conservation (SAC) and a Special Protected Area (SPA) under the Birds Directive, Sruwaddacon Bay is a haven for seabirds and marine mammals. Breeding terns, black‑headed gulls, red‑breasted mergansers and sand martins nest along the mudflats and sand dunes. The estuary’s waters are a recognised breeding ground for salmon, whales and dolphins, making early‑morning boat trips or shoreline observation rewarding for wildlife enthusiasts.
Coastal Walks & Views
The surrounding landscape offers several photogenic routes. A popular drive takes you over the Annie Brady Bridge—a narrow steel bridge rebuilt after the original 1886 structure was swept away in 1933—then across the Glenamoy River, before turning toward the townland of Bellagelly South. From the hill of Barrnacuillew (also known as Barr na Coille, “Top of the Wood”) you can enjoy sweeping panoramas of the entire estuary, the sand‑dune‑capped peninsula of Ros Dumhach, and the distant Atlantic horizon.
Heritage Sites
Just 300 m from the shoreline lies a megalithic court cairn or stone circle, recorded on OSI maps as a “megalithic tomb”. The area is peppered with historic placenames: Muingabo (the marsh of the cows), Gleann na Muaidh (Glen of the Moy or “of the Victories”), and Béal an Ghoile (the mouth of the stomach). These linguistic clues hint at a landscape shaped by both natural forces and centuries of human settlement.
Water‑Based Activities
The strong tidal currents make the bay popular with experienced kayakers and small‑boat enthusiasts. Guided sea‑kayak tours operate from Rossport during the summer months, offering close‑up views of the mudflats and the chance to spot seals and occasional dolphin pods. Always check the local tide tables before setting out; low tide reveals extensive mudflats ideal for wading and bird‑watching.
Photography
The ever‑changing light on the water, the dramatic sky at sunrise, and the contrast between the grey‑hound‑shaped channel and the surrounding dunes provide excellent opportunities for landscape photographers. The best light is usually just after sunrise or before sunset when the tide is low.
Local Amenities
The small village of Rossport sits at the estuary’s centre, offering a modest pier, the Denny’s Ferry Bar, Shop and Lounge, and a Gaelcholáiste (Irish‑language school). While the village is quiet—most activity consists of shore anglers and a few drift‑netting boats—it provides a genuine glimpse of rural Irish life.
Getting There
- By Car: The R310 regional road runs along the southern edge of the bay. From the N59, follow signs to Rossport; there is limited free parking at the pier and at the Denny’s Ferry Bar premises.
- Public Transport: Bus Éireann route 440 connects Ballina to Belmullet with a stop at Rossport on weekdays. The nearest train station is in Ballina, about 30 km away.
- Air: Ireland West Airport Knock is the closest airport (≈ 45 km). From there, hire a car or take a bus to Ballina and onward to Rossport.
- Cycling: The Annie Brady Bridge and adjoining low‑traffic country roads form part of a pleasant cycle loop linking Rossport to the surrounding farms and the coastal road to Bellacorick.
Best Time to Visit & Tides
Low tide (usually twice daily) is the prime time for bird‑watching and mudflat exploration. Spring and early summer bring the greatest variety of breeding seabirds, while late summer can offer sightings of migrating waders. Autumn can be rewarding for dolphin and seal watching as marine mammals move closer to shore.

Practical Information
Sruwaddacon Bay is free to access and has no formal opening hours; the estuary is open year‑round. Parking is available near the Rossport pier and at the Denny’s Ferry Bar premises, though spaces are limited during peak fishing periods. The narrow steel Annie Brady Bridge is suitable for pedestrians and cyclists; the local cycle route linking Rossport South (Ros Dumhach Theas) offers a pleasant, low‑traffic path for exploring the surrounding farmland and flower‑filled gardens.
Because the lower estuary experiences strong tidal currents, visitors interested in kayaking or small‑boat navigation should consult local tide tables and, where possible, join a guided excursion from Rossport. Bird‑watchers will find the best sightings at low tide when mudflats are exposed.
