Dog Parks in Dublin: Off-Lead Areas, Beaches and Rules

Last checked: 22 October 2026. Every rule below links to the government, council, park or transport page it comes from. Dublin has four councils, Dublin City, Dún Laoghaire-Rathdown, Fingal and South Dublin (find yours), and each sets its own park and beach rules, so read the signs at the gate too.

The short answers

• Where can my dog be off the lead? The law asks for control, not a lead: your dog must be with you and “under effectual control” (Control of Dogs Act 1986, s. 9). The government recommends a lead in public spaces (gov.ie), and council parks add their own lead rules, including set off-lead hours in Dublin City parks (below).
• Is there a dog park? Yes, mostly in the suburbs: South Dublin has seven, Fingal maps nine off-lead areas and Dún Laoghaire-Rathdown has them in six parks. Dublin City had one fenced dog run in July 2026, at St Anne’s Park in Clontarf (Dublin Inquirer, Jul 2026).
• Do I need a dog licence? Yes, for any dog over 4 months, and for a younger puppy once it has left its mother: €20 a year or €140 for life, from licences.ie or a post office. Without one, a dog warden can fine you €150 on the spot (Citizens Information).
• Does my dog need a muzzle? Only if it’s a restricted breed or a cross of one. Then, in public, it must be “securely muzzled” and on a strong lead of 2 metres or less, held by someone over 16 who can control it (Control of Dogs Regulations 1998, art. 5).
• Can my dog go on the Luas or the DART? The Luas, only in an enclosed pet carrier. The DART, only a small dog on your lap (details).
• Can my dog go on the beach? Yes, with seasonal rules. On Dollymount Strand, dogs can run off the lead in the green zone, except from 11am to 8pm in summer’s bathing season (beaches).

The rules everywhere in Ireland

Besides the licence:

• A microchip, registered on an approved database by 12 weeks old (Microchipping of Dogs Regulations 2015), with your details kept up to date (gov.ie). It costs about €25 (Citizens Information).
• A collar or harness with your contact details (gov.ie); the law asks for your name and address on it at all times (art. 6), and the government suggests your phone number too.
• Pick up the poo and bin it: “Any bag, Any bin!” (gov.ie). Leaving it is a litter offence: €250 on the spot since 1 September 2026, up from €150 (Litter Pollution Act 1997, s. 22; S.I. 278 of 2026), or up to €4,000 in court (Citizens Information).
• In the countryside, a lead at all times. The Department of Agriculture warns that a dog that only chases sheep can still kill lambs (gov.ie).

On-the-spot fines from a dog warden (S.I. 540 of 2023):

• No licence: €150
• No name and address on the collar: €200
• Dog not under effectual control: €300
• Restricted breed not muzzled or not on a proper lead: €300

Unpaid, most of these can go to court, with a maximum of €2,500, 3 months in prison, or both (Citizens Information).

Restricted breeds and XL Bullies

The list: American Pit Bull Terrier, Bull Mastiff, Doberman Pinscher, English Bull Terrier, German Shepherd (Alsatian), Japanese Akita, Japanese Tosa, Rhodesian Ridgeback, Rottweiler, Staffordshire Bull Terrier and Ban Dog (Bandog), plus their strains and crosses (gov.ie). The muzzle and short lead rule above applies to all of them; guide dogs don’t need the muzzle (Citizens Information).

XL Bully type dogs count as a cross of restricted breeds. Since 1 October 2024 no one may import, breed, sell or rehome one, and since 1 February 2025 it has been illegal to own one without a Certificate of Exemption from your council, or proof you applied; applications closed on 31 January 2025. A breach can mean the dog is seized and put down, plus a fine of up to €2,500, 3 months in prison, or both (gov.ie).

Dublin’s four councils

• Dublin City Council: its Control of Dogs Bye-Laws 1998, still in force, say a lead (fixed up to 2 metres, or retractable up to 10 metres) in its parks, open spaces, sports grounds and on the seashore, Sandymount Strand included, except from 8am to 11am and for one evening hour: 4pm to 5pm in December and January, 4.30pm to 5.30pm in February and November, 6.30pm to 7.30pm in March and October (5.30pm to 6.30pm on winter time), 7.30pm to 8.30pm in April and September, and 8.30pm to 9.30pm from May to August (bye-law text). Even then keep your dog under effectual control; you’re liable for any damage or injury it causes (parks strategy). The off-lead hours don’t apply on North Bull Island, which has its own zones (below), and dogs can’t go into council playgrounds. The council said in 2023 that its bye-laws need updating (council reply, Nov 2023). In July 2026 councillors agreed a motion asking for a plan for at least one off-lead area in each of the city’s 11 local electoral areas, and said a second dog park is planned in Herbert Park (Dublin Inquirer).
• Fingal: dogs in its parks and open spaces stay on a leash “other than in areas designated as off-leash areas”, and only guide and assistance dogs may go into playgrounds (parks bye-laws, 4.7; Fingal). Its 2019 guide maps off-lead areas at Ardgillan, Malahide, Newbridge (Donabate) and Santry demesnes, Millennium Park (Blanchardstown), Porterstown, St Catherine’s Park (Liffey Valley), Tyrrelstown Park and Ward River Valley (Swords) (Fingal user guide).
• South Dublin: “All dogs must be leashed when in Council owned parks” (South Dublin). It lists dog parks in Collinstown, Corkagh, Griffeen Valley, Jobstown, Sean Walsh (Tallaght), Tymon and Waterstown parks (parks list, page 2).
• Dún Laoghaire-Rathdown: a lead in its parks, except Killiney Hill Park and the off-lead areas in Cabinteely, Deerpark, Marlay, Shanganagh and Kilbogget parks. No dogs in the bathing areas at Seapoint and Sandycove all year, or at Killiney from 10am to 7pm, 1 June to 15 September, with a lead there at other times (DLR).

Where to go

• St Anne’s Park, Clontarf (Dublin City): the city’s one fenced dog run, with separate areas for big and small dogs, councillors said in July 2026. One called it “a very dangerous place for some animals and some small children” (Dublin Inquirer). The park opens at 10am and closes between 5pm (December, January) and 10pm (June, July), and gates can start closing half an hour early (Dublin City Council).
• Phoenix Park: more than 700 hectares, open 24 hours, with a herd of fallow deer (Heritage Ireland). The Office of Public Works (OPW) asks for a lead near the deer and in a few set areas (listed below), and bans dogs from the Ashtown Walled Garden and playgrounds (OPW code). The park’s bye-laws make you take reasonable care that your dog doesn’t chase or disturb the deer (bye-laws, 1926).
• St Stephen’s Green, Iveagh Gardens and the National Botanic Gardens (OPW): no dogs at the Green’s playground, lake or fountains, and a lead by its central flower beds; a lead everywhere in the Iveagh Gardens; no dogs at all in the Botanic Gardens. Guide dogs can go anywhere (OPW code).
• Tymon, Corkagh and Griffeen Valley parks (South Dublin): Tymon’s dog park has “accessibility for all visitors” (Tymon); Corkagh’s, near Clondalkin, is by the Camac Valley car park (Corkagh); Griffeen Valley’s, in Lucan, has benches and a viewing area (Griffeen).

Beaches

The bathing season runs from 1 June to 15 September (An Taisce, Blue Flag).

• Dollymount Strand, North Bull Island (Dublin City): a national nature reserve with three signed zones: red (no access), blue (dogs on lead) and green (off lead outside the bathing season, and in the season outside 11am to 8pm). Keep out of the salt marsh and the northern tip, and keep your dog on the lead in the dunes, where birds nest on the ground. Wilfully disturbing protected species is an offence (Dublin City Council). The council’s head of parks called the plan a “voluntary code” in April 2026 and said it is under review (RTÉ).
• Donabate and Portmarnock (Fingal): no dogs, except assistance dogs, in the Blue Flag area from 1 June to 15 September, 11am to 7pm. You may walk through on a lead along the dog access route at the back of the beach; stay off the dunes (Fingal, Jun 2025).
• Fingal’s other beaches: June to August, dogs on a lead in reserved bathing areas from 11am to 6pm, and always on a lead in protected nature sites (beach bye-laws, 2006).
• Any Blue Flag beach: in the bathing season, no dogs except assistance dogs in the Blue Flag area shown on the beach map, during the hours the council sets (An Taisce). In 2026 that means Killiney, Seapoint, Balcarrick (Donabate) and Velvet Strand (Portmarnock) (2026 list).

Buses, trams and trains

• Luas: dogs only “in an appropriate enclosed pet carrier case or box”, at staff discretion (Luas).
• DART and trains: a small dog travels free on your lap, on a lead unless it’s in a basket or container; restricted breeds are muzzled. Other dogs go only in a guard’s van, which Irish Rail has only on Dublin to Cork and Dublin to Belfast trains, so a bigger dog can’t ride the DART (Irish Rail).
• Dublin Bus: a dog may ride if it’s unlikely to annoy anyone or cause damage; the driver or inspector decides. Bus Éireann and TFI-branded buses carry only guide and assistance dogs (RTÉ, Mar 2026; TFI).
• Coming later: the National Transport Authority plans to allow small pets in carriers, and larger dogs on a lead and muzzled, on bus, rail and Luas (Irish Times, Sep 2026).

Walking several dogs

In OPW parks such as the Phoenix Park, the OPW asks for no more than 3 dogs per person (OPW code). No council sets a limit, but the control rule covers “the owner or any other person in charge of a dog” (Control of Dogs Act, s. 9), so a walker answers for every dog. Greyhounds and whippets: always on a lead in public, no more than 4 at a time (Citizens Information).

What to bring

• A lead, not an extendable one: the government doesn’t recommend them, or choke chains or electric collars (gov.ie).
• Poo bags and water. On warm days, see heatstroke in dogs.

Puppies: wait until your vet says the vaccine course is done before busy dog parks; see bringing home a puppy. Ticks: check your dog after long grass or woods; see how to check for ticks.

Manners

For the gate, play and scuffles, see dog park etiquette.

If your dog goes missing, contact your council’s dog warden, report it to the microchip database (Citizens Information), and report the lost or found dog free on FurFam: your report gets its own page to share.

FAQs

Can dogs go on the Luas? Only in an enclosed pet carrier or box, at the staff’s discretion. Guide dogs can travel (Luas).

How much is a dog licence in Ireland? €20 a year or €140 for the dog’s lifetime, for any dog over 4 months and for a younger puppy once it has left its mother, from licences.ie or a post office. No licence can mean a €150 on-the-spot fine (Citizens Information).

Can my dog be off the lead in the Phoenix Park? Only away from the deer. The OPW asks for a lead near the deer, in the People’s Gardens, around the Visitor Centre, near horse trekking and on cycle lanes, and bans dogs from the Ashtown Walled Garden and playgrounds (OPW).
