Can you do a good coastal day out from Dublin using just the DART?

Yes — the DART runs along the coast from Howth in the north to Greystones in the south, hugging Dublin Bay and the Irish Sea for most of its length. A single Leap Visitor Card covers unlimited travel for 1 or 3 days and lets you hop on and off at Howth, Malahide, Dún Laoghaire, Dalkey, Bray or Greystones at will. It is one of the best-value coastal day trips in Europe.

DART coastal day out from Dublin: the complete guide

The DART is Dublin’s best-kept day trip secret

The DART (Dublin Area Rapid Transit) has operated since 1984 and runs 54 km along the coast from Malahide and Howth in the north to Greystones in the south, passing through the heart of the city and skimming along sea walls, cliffs and coastal parks for much of its southern stretch. In good weather, the journey south from the city centre between Dún Laoghaire and Killiney — where the track runs along the clifftop above the Irish Sea with Killiney Bay spread below and the Wicklow Mountains behind — is genuinely scenic by any European standard.

The coastal DART corridor gives access to multiple excellent destinations within 30–45 minutes of the city centre for €3–4 with a Leap card, without a car, without a tour bus, and with trains running every 15–20 minutes during the day. A full coastal DART day, visiting several stops in sequence, is one of the most rewarding ways to experience the Dublin coast and a superb alternative to the standard Dublin city-centre tourist circuit.

This guide explains which stops deserve your time, in what order, for how long, and how to combine the DART with the bay boat cruises for a complete coastal loop.

Understanding the DART network

The main DART line runs from Malahide/Howth in the north through the city centre (Connolly, Tara Street, Pearse, Grand Canal Dock) and south to Bray. From Bray, a connecting diesel service (operated by Iarnród Éireann as part of the DART+ expansion) extends to Greystones. A separate northern branch serves Malahide independently of the Howth line — check which service you need before boarding, as not all trains on the northern section go to both Malahide and Howth.

DART trains run every 10–15 minutes during peak hours and every 20–30 minutes in the evenings and early morning. The full end-to-end journey from Howth to Greystones takes approximately 90 minutes and passes 33 stations. For a coastal day out, you will use a handful of these: the key stops are Howth, Sutton (for Howth Peninsula walks), Dún Laoghaire, Dalkey, Killiney and Bray.

The key stops and what they offer

Howth (northern terminus)

30 minutes from Connolly Station (or 28 minutes from Tara Street). The DART terminates right at Howth Harbour — you step off the train and you are on the waterfront without any onward connection. The harbour is active with fishing boats unloading, fish stalls selling prawns and crabs, and a scatter of excellent seafood restaurants.

From the harbour you have three main options: walk the East Pier (flat, 15 minutes to the lighthouse, good bay views); head up to the cliff walk (see the Howth cliff walk guide for route options); or take the Ireland’s Eye ferry from the harbour steps. A half-day guided coastal bus tour from Dublin to Howth is the guided option for those who want structured commentary.

Allow a minimum of 2 hours at Howth; a full half-day is better. The Howth day trip guide gives the complete Howth picture.

Malahide (Malahide branch, 25 minutes from Connolly)

Note: Malahide is served by a separate branch of the DART. Board a Malahide-bound service, not all trains go there. The station is about 15 minutes’ walk from Malahide Castle. See the Malahide Castle guide for full detail on the castle, gardens and butterfly house.

For a north-coast combination day, Malahide in the morning and Howth in the afternoon works well — Malahide Castle and gardens take 2–3 hours, leaving the afternoon for Howth’s cliff walk and seafood.

Dún Laoghaire (25–30 minutes from Tara Street)

The largest harbour on the south Dublin coast, with two long Victorian piers extending into the bay. The East Pier (1.3 km to the lighthouse) is the most popular walk in south Dublin: flat, sea-facing, and busy at weekends with local walkers, joggers and families. The views across Dublin Bay from the pier head take in the city skyline to the northwest, Ireland’s Eye and Howth Head to the north, and Howth Lighthouse and the open sea to the east.

The National Maritime Museum of Ireland is at the harbour (small but worthwhile for maritime history enthusiasts; closed Mondays). The People’s Park near the town centre has a good weekend farmers’ market. Dún Laoghaire is a genuine town with independent shops and cafés rather than a purely tourist destination — the main street (George’s Street) has useful places to eat and buy provisions for a coastal day.

The Dublin Bay cruise from city centre to Dún Laoghaire offers the unusual option of arriving by boat and departing by DART — useful as a one-way sea journey that eliminates backtracking.

Allow 1–2 hours at Dún Laoghaire.

Dalkey (one DART stop south of Dún Laoghaire, 35 minutes from Tara Street)

One stop south of Dún Laoghaire lies Dalkey, the most attractive of the south Dublin coastal villages. Medieval castle (living history tours), the Killiney Hill walking area immediately behind the village, boat trips to Dalkey Island, and a concentrated selection of good cafés and restaurants. A guided Killiney Hill and Dalkey Castle day tour covers both highlights with context and commentary.

Full detail in the Dalkey village guide. Allow 2–3 hours including Killiney Hill.

Killiney (one DART stop south of Dalkey)

A residential station, less infrastructure for visitors than Dalkey, but access to Killiney Beach (one of the better sandy beaches accessible from Dublin by public transport) and the coastal path south towards Shankill. The beach is pebbly at the north end and sandier at the south. On a summer day the contrast between the blue-green sea and the Wicklow Mountains behind is striking.

Bray (40–45 minutes from Tara Street, southern end of main DART line)

Bray is a proper Victorian seaside resort that has survived more or less intact from its railway age heyday. The promenade runs along a shingle beach with the typical ingredients: amusement arcades, fish-and-chip shops, ice cream, a bandstand and the sound of the sea. It is less polished than Dalkey or Dún Laoghaire but has an unself-conscious seaside character that is genuinely appealing.

Behind the promenade rises Bray Head — a 241 m headland with a coastal cliff path that runs south from the resort past the face of the head to the village of Greystones. The Bray Head cliff walk takes about 90 minutes one way (6 km) and provides exceptional views back over Bray, north across Killiney Bay, and south along the Wicklow coast. It is one of the finest accessible coastal walks in Leinster.

Allow 2–3 hours at Bray including the cliff walk section, or longer if doing the full walk to Greystones.

Greystones (via diesel from Bray)

The rail extension from Bray to Greystones runs alongside the cliff at the base of Bray Head — a genuinely spectacular stretch of track cut directly into the cliff face above the sea. Greystones itself has grown into an attractive coastal town with a strong food culture and a pleasant harbour. The combination of the cliff-walk from Bray (on foot, 2 hours) with the train back from Greystones is one of the best coast-and-rail circuits in Ireland.

Suggested itineraries

North coast half-day (4 hours)

Connolly → DART → Howth. Harbour + East Pier (1 hour). Cliff walk short section (1 hour). Seafood lunch (1 hour). Return DART. Optionally add the Ireland’s Eye ferry for a full-day version.

South coast half-day (4–5 hours)

City centre → DART → Dún Laoghaire. East Pier walk (45 min). DART south to Dalkey. Dalkey Castle and Killiney Hill (2 hours). Return DART. Optionally extend to Bray.

Full coastal loop (full day, 7–9 hours)

Start at Connolly → DART north to Howth (harbour walk + cliff section, 2 hours). Return DART south through city to Dún Laoghaire (East Pier, 45 min). DART to Dalkey (Killiney Hill, 2 hours). Optional extension to Bray (1.5 hours). Return DART. This is an ambitious but entirely achievable day — the DART makes every segment easy and the total journey time between stops is small.

Bay loop variation

City quays → boat cruise to Dún Laoghaire (70 min). East Pier walk. DART north to Dalkey. DART to Howth. Return DART to city. Mixes boat and train for maximum variety.

Fares and Leap card advice

Single fares on the DART are distance-based. Most city-centre to coastal-destination journeys fall in the €3.00–3.60 range with a Leap card (significantly more expensive as cash tickets — always use the card). The full breakdown is in the Leap card guide.

Leap Visitor Card (available at Dublin Airport and city centre newsagents): 1-day (€10), 3-day (€19.50), 7-day (€40). These cover unlimited travel on DART, Luas trams, Dublin Bus and Airlink airport buses. For a full coastal DART day with more than 3 journeys, the 1-day Visitor Card is better value than paying per-journey with a regular Leap card.

Children: under 5 free; under 16 at child rates. Family tickets are available through Irish Rail for groups.

Practical tips for your coastal day

Sea-view seats: on a southbound DART from the city, sit on the left-hand side (east side) for sea views from approximately Seapoint station onwards. The stretch between Dún Laoghaire and Dalkey is the most scenic — the track runs right along the top of the cliff in places.

Timing: arrive at Howth before 10:00 to be ahead of the summer weekend crowds. The DART from Connolly starts early (first service around 06:00). Avoid the 08:00–09:30 peak southbound (heavy commuter usage) and the 17:00–19:00 return peak — both directions are standing-room-only during commuter hours.

Eating on a coastal DART day: Howth has the best concentrated food (seafood stalls, fish and chips); Dún Laoghaire has useful cafés and a good Sunday market; Dalkey has quality sit-down restaurants; Bray has the traditional seaside eating experience. Plan food stops in advance on summer weekends — the popular places fill up.

Bad-weather option: the DART and the indoor options at each stop (Dalkey Castle, Dún Laoghaire Maritime Museum, the covered market) remain viable in rain. The cliff walks and harbour piers become less appealing but are usable in light rain with a waterproof.

The DART coastal day is central to a Dublin coastal 3-day itinerary and is the foundational framework for the day trips without a car guide. It also fits as the coastal half of a Dublin 3-day visit where one day is allocated to the coast and two to the city.
