Dublin 3-Day Itinerary: Trinity, Kilmainham, Northside

How should you spend 3 days in Dublin?

Spend day one on the Georgian south side, from the Book of Kells to the National Gallery, day two in the west at Kilmainham Gaol, IMMA, the Guinness Storehouse and St Patrick’s Cathedral, and day three north of the Liffey before an afternoon on the DART to Howth. Book Kells and Kilmainham first.

Three days in Dublin works best as three compact districts: the south city centre around Trinity and St Stephen’s Green, the old west side from Kilmainham to the Liberties, and the Northside and the docks, with the coast as a reward. The Dublin 7-day itinerary spreads these sights over four slower city days and adds full days in Howth, Glendalough and Belfast; this plan pairs them differently so that each day stays on foot or one tram line.

Two big closures shape late 2026. Dublin Castle’s campus is closed until January 2027 while Ireland hosts the Presidency of the Council of the EU (Dublin Castle), and the Chester Beatty is closed from 15 June to the end of December 2026 (Visit Dublin). In the Long Room at Trinity, all books have been removed for the Old Library Redevelopment Project except the first four bays as you enter (Trinity).

This plan uses venues’ and operators’ own pages, checked on 16 and 17 October 2026. Choose a base with where to stay in Dublin, and check the season with the best time to visit Dublin.

What does the 3-day Dublin plan look like at a glance?

Day one stays south of the river around Trinity and Merrion Square, day two runs west from Kilmainham to the Liberties, and day three starts on O’Connell Street and the docks before the DART to Howth. The table shows the anchors, what to book, the closures that decide the order and a swap for rain.

Two weekly patterns decide the order. The National Museum of Ireland – Archaeology opens only from 1pm to 5pm on Sundays and Mondays (National Museum), and IMMA closes on Mondays except bank holidays (IMMA). GPO Witness History closes on Sundays and public holidays (GPO).

That makes a Thursday or Friday start the easiest: days one and two fall on weekdays or Saturday, and day three avoids Sunday at the GPO. If day three lands on a Sunday, swap the GPO for EPIC, which opens seven days a week (EPIC).

What should you book before three days in Dublin?

Book two things before you fly: a timed Book of Kells ticket, from €25 with the digital exhibition or €19 for the manuscript and Old Library, and a Kilmainham Gaol tour, €8, which must be pre-booked on the official sites. Add the Guinness Storehouse a day or two ahead; everything else can wait.

Trinity says online booking is strongly recommended, entry is timed and tickets are non-refundable once bought; the €25 Book of Kells Experience includes the Old Library and the Red Pavilion digital exhibition, while the €19 ticket covers the Book of Kells and the Old Library only (Trinity).

Kilmainham Gaol is by guided tour only, and tickets must be pre-booked online through its own site or Heritage Ireland: tickets bought from third parties are not valid (Kilmainham Gaol). The Guinness Storehouse lists tickets from €24 (Guinness Storehouse), GPO Witness History charges €15 online or €17 at the door (GPO), and EPIC €22 online (EPIC).

The National Museum’s archaeology collection, the National Gallery and IMMA are free (National Museum, National Gallery, IMMA), which keeps a three-day budget in check.

Day 1: how do you see Trinity and the Georgian south side?

Take the first Book of Kells slot, at 8.30am on weekdays and Saturdays or 9am on Sundays, then walk to the National Museum’s archaeology collection on Kildare Street and the National Gallery on Merrion Square. Finish at the Little Museum of Dublin on St Stephen’s Green and spend the evening in Temple Bar.

The Book of Kells Experience opens from 8.30am to 6.30pm from Monday to Thursday, to 7pm on Fridays and Saturdays and from 9am to 6.30pm on Sundays; the main ticket allows about 90 minutes (Trinity). The free National Museum of Ireland – Archaeology opens from 10am to 5pm from Tuesday to Saturday but only from 1pm to 5pm on Sundays and Mondays (National Museum), and the free National Gallery stays open to 8.30pm on Thursdays (National Gallery).

The Little Museum of Dublin, open from 9.30am to 5pm, includes a guided tour in every ticket and warns that tours book up quickly (Little Museum). Visit Dublin describes Temple Bar as a cobbled district on the south bank of the Liffey, known for old-school pubs, live music and trad sessions, with the Irish Film Institute and Photo Museum Ireland among its venues (Visit Dublin).

Industrial action closed the National Gallery and the National Museum on single days in October 2026 (National Gallery), so check both sites on the morning you go. The UK government advises guarding against bag-snatching and pickpocketing, which happen mostly in larger cities (FCDO).

Day 2: how do you combine Kilmainham Gaol, the Guinness Storehouse and St Patrick’s?

Take the earliest Kilmainham Gaol tour you can book, then cross to IMMA in the Royal Hospital Kilmainham, which is free and closed on Mondays. Head east to the Guinness Storehouse, open from 9.30am daily, and end at St Patrick’s Cathedral before an evening in the Liberties. This west-side loop suits any day except Monday.

Kilmainham Gaol opens all year except 24 to 27 December; its visitor centre opens from 9.30am to 5.15pm and the museum from 10.30am, and the guided tour of the building lasts an hour, with about 90 minutes needed for the full visit (Kilmainham Gaol). IMMA opens from 10am to 5.30pm on Tuesdays and from Thursday to Saturday, from 11.30am on Wednesdays and from noon on Sundays and bank holidays, with last admission to the galleries at 5.15pm (IMMA).

The Guinness Storehouse opens at 9.30am every day and lists tickets from €24 (Guinness Storehouse). St Patrick’s Cathedral opens at 9.30am on weekdays and 9am on Saturdays, with adult tickets at €11.50; Sunday visits fit between services, and there are no guided tours that day (St Patrick’s Cathedral).

The Luas Red Line runs east along the river from Heuston towards the centre (Luas), which helps if your legs give out. Dublin Castle would fit this day, but its campus is closed until January 2027; after it reopens, it lists daily hours of 9.45am to 5.45pm (Dublin Castle).

Day 3: how do you combine the Northside with an afternoon on the coast?

Start at GPO Witness History on O’Connell Street at 10am, then walk along the quays to EPIC, the Irish emigration museum. After lunch, take the DART from Connolly to Howth, about 25 minutes, for the harbour and the start of the cliff path. On Sundays, when the GPO is shut, begin at EPIC instead.

GPO Witness History opens from 10am to 5pm from Monday to Saturday, with last admission at 4pm, and closes on Sundays, public holidays and Christmas Eve (GPO). EPIC, in the CHQ Building on Custom House Quay, opens every day from 10am to 6.45pm, with last entry at 5pm (EPIC). If you are here from Wednesday to Sunday and prefer architecture, 14 Henrietta Street runs pre-booked tours on the hour from 10am to 4pm (14 Henrietta Street).

Irish Rail’s DART timetable shows about 25 minutes from Connolly to Howth, with direct daytime trains at 8, 28 and 48 minutes past the hour on weekdays (Irish Rail); until 12 December 2026 a revised autumn timetable adds one to three minutes to some peak trains (Irish Rail). The full Howth Cliff Path Loop is 7.8 km, about two hours, from the DART station (Sport Ireland), so an afternoon allows part of it and the harbour.

In wind or rain, swap Howth for Malahide Castle on the other DART branch, open daily from 9.30am to 5.30pm (Malahide Castle). The Dublin 7-day itinerary gives Howth a full day if you can stay longer.

How do you adjust the plan for Dublin’s weather?

Expect rain on any day: Met Éireann’s Dublin Airport averages record 137 days a year with at least 1mm, with October and November the wettest months. Days one and two are almost entirely indoors, so the coast afternoon on day three is the one to move. Check Met Éireann’s warnings before Howth.

Met Éireann’s 1991–2020 averages give 772.5mm of rain a year at Dublin Airport, with 78.4mm in October and 82.7mm in November (Met Éireann). Its warnings run from yellow through orange to red, the last for rare and extremely dangerous weather (Met Éireann); on an orange or red day, skip the cliff path.

For the year-round picture, see the best time to visit Dublin. The table shows simple swaps that keep the three districts intact.

How do you get around Dublin and to and from the airport?

Walk inside each district and use the Luas between them: the Green Line runs through St Stephen’s Green and O’Connell Street, the Red Line along the quays. A Leap card caps fares at €6.00 a day. There is no rail link to the airport, so arrive by coach or taxi, which costs about €30 to €45.

With a Leap card, the TFI 90 Minute Fare costs €2.00 for adults and is capped at €6.00 a day and €24.00 a week across Dublin Bus, Luas, DART and commuter rail (Luas). The two Luas lines meet at O’Connell–GPO (Luas), and the DART runs from Howth and Malahide through Connolly, Tara Street and Pearse to the southern coast (Irish Rail).

Dublin Express lists a first airport coach at 03:05 and a last at 00:35 (Dublin Express), Dublin Airport estimates a taxi to the city at €30 to €45 (Dublin Airport), and TFI Leap Visitor Cards are sold in both terminals (Dublin Airport). Compare the options in Dublin Airport bus vs transfer.

For three days, a base near St Stephen’s Green or O’Connell Street keeps all three districts within a walk or one tram ride; where to stay in Dublin compares eight areas, and Dublin hotels and the Dublin destination guide fill in the rest.

Which dates and seasons change a short Dublin trip?

St Patrick’s week, 13 to 17 March 2027, and the October bank holiday weekend bring the biggest crowds, and Christmas closes many sights: Kilmainham Gaol from 24 to 27 December and the National Gallery from 24 to 26 December. From January 2027, Dublin Castle reopens and fits neatly into day two.

The Bram Stoker Festival runs from 23 to 26 October 2026 (Bram Stoker Festival), and the Dublin Marathon starts at 8.45am on Sunday 25 October (Dublin Marathon), so expect closed roads that morning. NYF Dublin, the New Year festival, runs from 30 December 2026 to 1 January 2027 (Visit Dublin), and the St Patrick’s Festival from 13 to 17 March 2027 (St Patrick’s Festival).

Holiday closures matter on a short trip: Kilmainham Gaol closes from 24 to 27 December (Kilmainham Gaol), the National Gallery from 24 to 26 December (National Gallery), and the GPO on public holidays and Christmas Eve (GPO).

After the closures end, the plan grows: Dublin Castle reopens in January 2027 (Dublin Castle), and the Chester Beatty’s closure runs only to the end of December 2026 (Visit Dublin), so both can join day two in 2027.

Which tours fit three days in Dublin, and who should change the plan?

A walking tour of Georgian or literary Dublin suits day one, and a pub or trad-music evening suits any night. Book Kilmainham only through its own site, because third-party tickets are not valid. Families can trade the Guinness Storehouse for EPIC, and anyone with more time should add Glendalough or Belfast.

Before booking a tour, check the meeting point, length, what entry is included and the cancellation terms; listings are not endorsements. For Kilmainham, the gaol says public tour tickets are sold only on its own website or Heritage Ireland (Kilmainham Gaol). Our GetYourGuide vs Viator vs Klook comparison explains the platforms’ cancellation rules.

With extra days, the Dublin 7-day itinerary adds Glendalough and Belfast, and Dublin to Belfast by train or plane covers the trip north. For more ideas, see things to do in Dublin.
