Overview
The Dublin–Wicklow railway line is one of Ireland’s most reliable and scenic transport routes, linking the capital with the coastal and mountainous landscapes of County Wicklow. Operated by Iarnród Éireann (Irish Rail), the corridor is split into two complementary services: the DART (Dublin Area Rapid Transit), which runs every 15 minutes on weekdays from Howth and Malahide south to Greystones, and the South East Commuter service, which continues beyond Greystones through Arklow to Wicklow town. Together, they provide a fast, car-free way to explore the “Garden of Ireland” while keeping passengers close to the Irish Sea.
The Route & Key Stops
The line’s greatest strength is how it strings together distinct destinations without requiring transfers. From Dublin’s city centre stations, the train quickly leaves the urban grid and begins skirting the coast. Key stops include:
- Bray – A vibrant seaside town with a long promenade, independent shops, and the starting point for the popular cliff walk. The station sits just steps from the main street and beach.
- Greystones – The southern terminus of the DART, known for its wide sandy beach and relaxed atmosphere. It’s a popular launch point for coastal walks and cycle routes.
- Arklow – A historic port town where the commuter line briefly moves inland. Arklow serves as a transport hub for visitors heading to the Wicklow Mountains, with regular bus and coach connections to Glendalough and the surrounding valleys.
- Rathdrum – A key stop in the wooded hills of central Wicklow, providing access to the Avondale Forest Park (featuring the historic Avondale House and the popular Treetop Walk) and the nearby village of Avoca (note that the railway station at Avoca itself closed in 1964, making Rathdrum the closest active rail stop for the area).
- Wicklow Town – The line’s final stop, offering direct access to the town centre, local markets, and the gateway to the Wicklow Mountains.
History & Evolution
The railway’s origins date to the mid-19th century, when the Dublin, Wicklow & Wexford Railway began constructing a route to connect Dublin with the southeast. Building a line along a rugged, erosion-prone coastline was a significant engineering challenge, requiring extensive viaducts, cuttings, and sea walls. Following nationalisation in the 1940s and subsequent integration into Córas Iompair Éireann (CIÉ), the line operated as a conventional steam and diesel commuter route for decades. The 1980s brought a major transformation with the electrification of the Dublin to Greystones section, launching the DART system and dramatically increasing service frequency. Today, the line operates as a modern, high-capacity corridor while retaining its original coastal alignment and historic stations.
Walking & Cycling Alongside
The railway shares much of its southern stretch with the Bray to Greystones Cliff Walk, an 8.5 km (5.3 mile) coastal trail that follows the original rail embankment. The path is well-maintained, dog-friendly, and largely flat, making it suitable for families and casual walkers. Cyclists can use the route but must dismount at a few narrow sections where the trail passes through rock cuts. The walk begins near Bray Daly station, crosses the railway line at Crab Rock, and finishes close to Greystones station. Visitors often combine the trail with a DART ride back to Bray or Dublin, creating a stress-free loop. Further inland, commuter stations near Arklow and Wicklow town provide access to the Wicklow Way and the Dublin Mountains Way, allowing walkers to extend their journey into the uplands.
Wildlife & Coastal Views
Travelling along the Irish Sea coast offers consistent opportunities for wildlife spotting. On clear days, passengers on the left-hand side (facing south) can watch for dolphins, common porpoises, and occasionally basking sharks further offshore. The cliff edges and sea stacks are home to breeding seabirds, including gannets, kittiwakes, fulmars, and great black-backed gulls. During spring and summer, the embankments and cuttings bloom with native wildflowers, gorse, and heather, adding colour to the journey. The line also passes several designated Special Areas of Conservation, where coastal grasslands support rare invertebrates and nesting terns.
Practical Travel Tips
- Tickets & Fares – Use the Irish Rail Journey Planner to purchase single, return, or day tickets. A Leap Card offers pay-as-you-go convenience across the DART and commuter network. The Family Day Pass (2 adults and up to 4 children) provides unlimited travel for €20.
- Dogs – Leashed dogs travel free on all DART and commuter services. Larger breeds may be required to wear a muzzle depending on station signage.
- Accessibility – Each train has a limited number of wheelchair-accessible spaces and step-free boarding at select stations. Book these spaces in advance through the Journey Planner to guarantee availability.
- On-board amenities – Trains are equipped with free Wi-Fi and power sockets at most seats, but there is no trolley or catering service on this route, so passengers should bring their own refreshments. Luggage space is available in designated areas near the doors.
- Service updates – Ongoing coastal defence and track improvement works occasionally require weekend engineering possessions. Check the Irish Rail service updates page before travelling, especially during peak summer months.
Getting There & Ticketing
Reaching the line from Dublin is straightforward. Passengers arriving at Dublin Airport can take the Airlink bus to Dublin Connolly station in approximately 30 minutes, then board a southbound DART. From Dublin city centre, direct services depart from Connolly, Pearse, Tara Street, and Pearse Street. The journey to Greystones takes roughly 45 minutes, while reaching Wicklow town via the commuter service takes around 60–70 minutes depending on stops. For visitors planning multi-day exploration, Irish Rail offers flexible rail passes and discounted web fares when booked at least seven days in advance. The line’s integration with local bus networks and the Luas tram system at Connolly station makes it a practical hub for car-free travel across the east coast.
