Parks and Gardens

Dublin is greener than you'd expect from a capital city. Within minutes you can go from the bustle of the city centre to the sprawling Phoenix Park, a Victorian garden square, or a stretch of coastline with cliff paths. Most of the green space is free and open all year – the only place you'll pay is Dublin Zoo.

This overview sorts the best options by effort and character, from a quick breather between sights to a full day out by the sea.

Phoenix Park – the green giant in the west

Phoenix Park is the heavyweight among Dublin's green spaces. At around 708 hectares (about 1,750 acres), it's one of the largest enclosed public parks of any European capital. It was laid out in the 1660s as a royal deer park and has been open to the public since 1747; today it's accessible around the clock.

If you don't fancy covering the ground on foot, cycling is a good option – the park has a network of paths totalling around 14 kilometres. Popular loops (distances and times come from hiking portals rather than the official park authority, so treat them as guidelines):

• Big Park Loop – around 12.4 km, about 3 to 3.5 hours on foot. The classic route linking most of the highlights.
• Short Loop – about 5 km, around 70 minutes. Good for a quick taste of the park.
• Old Town Wood Loop – about 7.4 km, around 1 hour 45 minutes. The woodier option.

Landmarks inside the park include the Wellington Monument, an obelisk completed in 1861 standing a good 62 metres tall and the tallest obelisk in Europe, and the Papal Cross, a white steel cross erected for the papal visit in 1979. Also worth seeing are the Magazine Fort, a gunpowder store dating from 1734, the Victorian / People's Flower Gardens, the Glen Pond in the Furry Glen, and Ashtown Castle by the Visitor Centre. The Irish President's official residence, Áras an Uachtaráin, also sits within the park, with free guided tours on Saturdays.

For a break, head to the Victorian Tearooms near the zoo or the Phoenix Café by the Visitor Centre. Toilets are available; mobile toilets were added at the Papal Cross car park in 2021.

The fallow deer of Phoenix Park

The park's signature residents are its free-roaming fallow deer. The herd numbers over 500 animals, descended from deer introduced in the 17th century. You can see them year-round, most reliably around the Papal Cross and on the open grassland of the Fifteen Acres, as well as along the tree lines between the Magazine Fort and the Visitor Centre.

Your best chances are in the quiet early morning hours, and the animals are especially active during the autumn rut. One thing to remember – these are wild animals. Keep at least 50 metres away and never feed or touch them, especially in early summer, when fawns lie low in the grass.

Dublin Zoo – wildlife inside Phoenix Park

Inside Phoenix Park you'll find Dublin Zoo, one of the oldest zoos in the world (founded in 1831). Over 400 animals live across themed habitats: the African Savanna is home to white rhino, Rothschild's giraffe, Grant's zebra and scimitar-horned oryx, the Kaziranga Forest Trail houses Asian elephants (since 2005), and the Gorilla Rainforest is home to western lowland gorillas (since 2012). There's also the Orangutan Forest with Bornean orangutans and an area for Sumatran tigers. Allow at least three hours for a visit.

The zoo is open 363 days a year – closed only on 25 and 26 December – daily from 9:30. Closing time varies by season: 16:00 in January (last admission 15:00), 17:00 in February, 18:00 from March to September (last admission 17:00), and 16:00 in November and December.

Admission prices for 2026 (gate / online):

• Adults – €26.50 / €22.50
• Children aged 3 to 15 – €20.00 / €17.00; free under 3
• Seniors (65+) and students – €21.00 / €17.50
• Family (2 adults + 2 children) – €75.00 / €62.50; larger family tickets (2+3, 2+4) priced accordingly

Booking online saves up to 15 per cent on the gate price. If you're combining several attractions, it's worth checking whether the Dublin Pass, which includes the zoo, works out cheaper.

St Stephen's Green – the garden square in the centre

If Phoenix Park is the day trip, St Stephen's Green is the pause in between. The park at the southern end of Grafton Street covers 22 acres (8.9 hectares), making it the largest of Dublin's Georgian garden squares. The grounds were enclosed in 1664; the Victorian redesign was paid for by Arthur Edward Guinness (Lord Ardilaun), and the park officially reopened to the public on 27 July 1880. Tree-lined avenues, a duck pond, pavilions and a bandstand used for summer concerts still shape the park today.

The park also doubles as an open-air museum of Irish history. At the main entrance stands the Fusiliers' Arch from 1907, whose bullet scars from the 1916 Easter Rising earned it the nickname "Traitor's Gate" – during the Rising the park was occupied by the Irish Citizen Army, with a daily ceasefire so the park keeper could feed the ducks. Inside you'll find the Yeats Memorial Garden with a sculpture by Henry Moore, a bust of James Joyce, statues of Countess Markievicz and Robert Emmet, and a Famine memorial.

National Botanic Gardens and Merrion Square

A little north of the centre, in Glasnevin, lie the National Botanic Gardens (founded in 1795). Admission is free, and the grounds are home to over 15,000 plant species. The restored glasshouses – the Turner Curvilinear Range and the Great Palm House – are famous, with a restoration that won a Europa Nostra award. There are also herbaceous borders, a rose and alpine garden, a pond, a rock garden and an arboretum – a rewarding option especially in changeable weather, when you can duck into the glasshouses.

If you're exploring Georgian Dublin south of the river, make a detour to Merrion Square Park. The garden square has served as a public park since 1880 – again with Arthur Edward Guinness having a hand in it. It's known for the colourful, reclining Oscar Wilde statue at the north-west corner and its flower beds. A quiet, short stop between the museums around the square.

Howth – cliff walk and boat trip out to sea

For the bigger outing, head for the coast: the fishing village of Howth, on the peninsula of the same name north-east of the city, has Dublin's finest cliff paths. The DART gets you there from Dublin Connolly in around 26 minutes to the Howth terminus; trains on this stretch run roughly every ten minutes during the day, less frequently in the evening and early morning. For more on tickets, see our guides to the Leap Card and public transport.

Several colour-coded loops start from the station, all in the harbour village:

• Cliff Path Loop (green) – the official Sport Ireland route is 7.8 km long, takes around 2 hours, is rated "moderate" and has about 130 metres of elevation gain. Marked with green arrows, with views over Ireland's Eye, Lambay Island and Dublin Bay.
• Tramline Loop (blue) – around 7 km, about 2 hours.
• Black Linn Loop (red) – around 8 km, about 2.5 hours, taking in the highest point on the peninsula.
• Bog of Frogs Loop (purple) – around 10 km, about 3 hours, moderate to challenging.

Boats to the small bird sanctuary of Ireland's Eye leave from the West Pier. Ireland's Eye Ferries departs from the pontoon at the end of the West Pier; 2026 prices are €25 for adults, €15 for students and children, and €60 for a family (2 adults + 2 children), with free cancellation up to 24 hours ahead. A second operator, Howth Cliff Cruises, gets you across in around 15 to 20 minutes; return trips typically leave on the half-hour. Schedules depend heavily on season and weather, so check current times locally or in advance.
