Overview
Kilcoole Marshes sit just south of the village of Kilcoole on the east coast of County Wicklow. This flat, brackish landscape is defined by a long barrier beach that formed after the last Ice Age when rising sea levels trapped sediment behind a ridge of sand and shingle. Together with the marshes near Wicklow town, it creates the Murragh, the largest wetland complex on Ireland’s east coast. Designated as a Special Protection Area (SPA), the site is legally protected due to its value for endangered species. While the area is wild today, archaeological surveys in the surrounding townlands have uncovered fulacht fiadh (ancient boiling houses), bullaun stones, and holy wells, proving that humans have valued this fertile coastal strip for millennia.
Wildlife & Birdwatching
The marshes are best known for their birds. The adjacent barrier beach hosts Ireland’s only colony of little terns, making it a nationally significant site for seabirds. During the breeding season, these small, agile birds nest on the shingle, while the salt-marsh and grassland support a rotating cast of visitors. Summer brings nesting redshank, shelduck, and mute swans. As the weather turns, the grassland fringe becomes a feeding ground for large flocks of whooper swans, Bewick’s swans, greylag geese, and brent geese.
Waterfowl enthusiasts will spot wigeon, teal, mallard, and shelduck year-round, with rarer arrivals like pintail, shoveler, pochard, goldeneye, and gadwall appearing throughout the year. Beyond the birds, the wetter patches host frogs and dragonflies, adding to the soundscape of the marsh. The brackish water and tidal flats create a rich food web that supports invertebrates, amphibians, and small mammals, making this a complete ecosystem rather than just a birding post.
Walking & Photography
Visiting the marshes is straightforward. The terrain is flat and open, making it ideal for unobstructed walks and photography. The lack of trees means you have sweeping views across the Irish Sea, which is perfect for capturing sunrise and sunset over the water. Birdwatch Ireland’s Wicklow branch organises regular guided walks, meeting at the Kilcoole railway station car park. These sessions are led by volunteers who help spot shy species and explain the ecology of the salt-marsh. For independent visitors, there is no charge to enter, and the site is open year-round.
Photographers will find the low-lying grasses and reeds provide excellent foreground interest when framing shots of the sea or distant birds. A telephoto lens is highly recommended for capturing the little terns on the beach, while a wide-angle lens works well for the expansive marsh landscape. Early morning light tends to be softest, and the stillness of the water often creates mirror-like reflections of the sky.
Seasonal Guide
The wildlife changes noticeably with the calendar:
- Spring (March–May): Arrival of breeding waders such as redshank and the start of the little tern nesting season on the barrier beach.
- Summer (June–August): Peak nesting activity; good chance to see mute swans and shelducks raising chicks.
- Autumn (September–November): Migration of geese and ducks; Birdwatch Ireland often organises September walks to coincide with these movements.
- Winter (December–February): Large numbers of whooper and Bewick’s swans, as well as brent and greylag geese, use the marshes as a feeding ground.
Practical Information
Access is easiest via the Kilcoole railway station car park, located on the north side of the station. This is also the meeting point for organised events, which typically start at 10:00 am. The car park is level, and a paved pathway leads directly to the marsh edge, which is suitable for visitors with limited mobility. However, the natural grass and mud paths beyond the entrance can become soft after rain, so sturdy footwear is recommended.
Getting there
- By train: Kilcoole railway station is served by Iarnród Éireann on the Dublin–Rosslare line. On weekdays there are early-morning and late-afternoon services; weekend services have increased since December 2022, with several trains each day. The station is a short walk from the marshes.
- By bus: Dublin Bus X1 and X2 routes connect Kilcoole with Dublin. The L2 route terminates at Bray, from where a local bus or taxi can reach Kilcoole.
- By car: From Dublin, take the M11 south to the exit for Kilcoole. Follow the signs to the railway station; the car park is on the station’s north side.
Conservation & Etiquette
Because this is a sensitive habitat, visitors are asked to stay on marked paths, keep a respectful distance from nesting sites, and keep dogs on a short lead between March and July. The marshes rely on natural tidal flows and seasonal grazing to maintain their biodiversity, so sticking to established routes helps prevent soil compaction and protects ground-nesting birds.
Local amenities
Kilcoole village offers a small selection of cafés and a convenience store within a short walk from the marshes. For a longer break, the nearby town of Greystones (≈5 km north) provides a wider range of restaurants, pubs and accommodation options. Before heading out, check the tide times, as low tide exposes more of the mudflats and attracts different wading species to the lower reaches of the marsh.
