Open-top buses and what they are actually good for
Dublin’s hop-on hop-off buses are frequently dismissed as tourist traps and occasionally recommended as the best way to spend a first morning in the city. Both reactions contain some truth. The buses are explicitly designed for visitors who want an overview without the work of planning routes, and they deliver that efficiently. What they are not is an alternative to exploring Dublin on foot — the city is compact enough that walking is often faster and always more satisfying.
The three main operators — the Original (green bus), Big Bus, and City Sightseeing — cover broadly the same route with similar prices and similar commentary. Choosing between them is less important than deciding whether a hop-on hop-off pass makes sense for your trip at all.
The Original green bus
The Original Dublin hop-on hop-off green bus is the oldest-established operator and the most integrated with the Dublin Pass. Its route covers approximately 23 stops across a single main loop taking around 90 minutes to complete, including Trinity College, St Stephen’s Green, Merrion Square, the IFSC, Custom House, Croke Park (on some routes), O’Connell Street, the Guinness Storehouse, Kilmainham Gaol and Phoenix Park.
Buses run every 10-15 minutes on the main loop during peak hours, every 20-30 minutes at quieter times. The 24-hour and 48-hour passes allow unlimited rides on the full network during the validity period.
The green bus’s main practical advantage is the Guinness Storehouse stop. If you are combining a Storehouse visit with any of Dublin’s northside or southside sights, the bus eliminates the need to navigate public transport between them. The Storehouse is in the Liberties — a 15-minute walk from the city centre that many visitors underestimate — and the bus handles the geography efficiently.
Big Bus Dublin
Big Bus runs open-top double-deckers with live commentary on some services (pre-recorded on others) and operates a similar central Dublin loop. The 24-hour pass extends to 72 hours on some booking combinations, making it better value for visitors spending more than two days in the city.
Big Bus also operates a nighttime panoramic tour — a separate one-hour circuit of Dublin’s illuminated landmarks — which is a genuine addition if you are interested in Dublin’s nighttime aesthetics. The combination of a day pass and an evening tour is a coherent proposition.
In terms of route and stop coverage, Big Bus and the Original green bus are near-identical for practical purposes. The main differentiator is commentary quality — this varies by individual guide and is genuinely difficult to predict. If live guides matter to you, check recent reviews for the specific operator.
City Sightseeing Dublin
City Sightseeing uses the familiar red double-deckers seen in cities across Europe and provides audio commentary via headphone in multiple languages. This makes it the clearest option for non-English-speaking visitors who want commentary in their own language — typically available in French, German, Spanish, Italian, and several others.
The route and stop coverage is comparable to the other two operators, and prices are similar. City Sightseeing’s multi-language audio is its strongest differentiator; for English-speaking visitors, there is little to choose between it and the Original green bus.
How to use the bus effectively
The mistake most visitors make is treating the hop-on hop-off bus as a primary transport tool and then being frustrated by traffic, frequency gaps, or stops that are not quite where they want to be. The bus works best as a supplement to walking and public transport, not a replacement for them.
The most useful stops for most visitors are:
- Guinness Storehouse: saves the 15-minute walk from the city centre and the confused navigation through the Liberties
- Kilmainham Gaol / Kilmainham area: 30 minutes west of the city centre, the bus removes the need for a taxi or multiple bus changes
- Phoenix Park: the Park is large and the bus drops you at the main entrance, giving you a starting point for exploring on foot
- Docklands / Convention Centre area: useful if you are staying in a city-centre hotel and want to see the modern Dublin waterfront
For sights within the city centre — Trinity College, Dublin Castle, St Patrick’s Cathedral, St Stephen’s Green — you are better off walking. The bus adds time rather than saving it for short city-centre hops.
The bus tour versus the Dublin Pass question
The Dublin Pass (from around €89 per day) includes a 72-hour hop-on hop-off bus pass from the Original green bus operator, plus entry to the Guinness Storehouse and 40+ other paid attractions. If you are planning three or more major paid sights in a day, the Pass often pays for itself — and the included bus pass makes the logistics of moving between them smoother.

Frequently asked questions about Dublin hop-on hop-off bus
Is the Dublin hop-on hop-off bus worth it?
It depends on how you use it. If you ride the whole loop without hopping off, you are paying €20-25 for a 1.5-hour sightseeing tour — reasonable but not exceptional. The real value is as flexible transport between sights over a 24-48 hour pass. Used to reach the Guinness Storehouse, Phoenix Park, Kilmainham Gaol and the Docklands without planning public transport routes, it pays for itself. For confident city navigators who are happy with the DART and Luas, it is less necessary.What is the difference between the green bus, Big Bus and City Sightseeing?
All three cover Dublin's main sights on an open-top double-decker bus with audio commentary. The Original (green bus) is the longest-established operator and covers a single loop of around 90 minutes. Big Bus runs a similar route with live guides on some services. City Sightseeing uses the internationally familiar red buses and runs comparable commentary. Prices are similar across all three.How many stops does the Dublin hop-on hop-off bus have?
The main loop has around 20-23 stops depending on the operator, covering Trinity College, St Stephen's Green, Merrion Square, the Docklands, the Convention Centre, Croke Park (some routes), the Custom House, the Guinness Storehouse, Kilmainham Gaol, Phoenix Park, and back to O'Connell Street. Some operators run a second northern or coastal loop as an extension.Does the hop-on hop-off bus go to Howth or Malahide?
No. The standard Dublin hop-on hop-off loops cover the city centre and inner suburbs only. For Howth, Malahide, Dún Laoghaire or coastal towns, use the DART rail line or a dedicated day tour. The DART runs frequently and is excellent — see the DART and coastal day trip guide.Can you use a Dublin Pass on the hop-on hop-off bus?
The Dublin Pass includes a 72-hour hop-on hop-off bus pass from the Original (green bus) operator. This is one of the Pass's most tangible inclusions and one of the reasons the Pass can represent good value for first-time visitors planning multiple attractions.When is the best time to take the hop-on hop-off bus?
The first departure of the day (usually 09:00-09:30) is the quietest and gives you the best chance of getting an unobstructed front seat on the upper deck. Summer afternoons are the busiest. If you are doing the full loop without hopping off, a clear morning gives the best views. Sunset on the upper deck in summer (the sun sets around 22:00) is memorable.
