Best Dog Parks in Dublin: 8 Off-Leash Spots Every Owner Should Know (2026 Guide)

Best Dog Parks in Dublin: 8 Off-Leash Spots Every Owner Should Know (2026 Guide)

Dublin has more genuinely great off-leash space than most owners realise — you just need to know which of the city's four councils runs which park, and when the off-lead hours actually apply. Below is a council-by-council breakdown of the best dog parks in Dublin, covering enclosed dog runs, off-leash hillwalks, and the rules that keep a walk from turning into a fine.

Quick answer: the best all-round off-leash dog parks in Dublin are Marlay Park (Rathfarnham) for a proper enclosed run, Killiney Hill Park for a fully off-lead scenic walk, St Anne's Park (Clontarf/Raheny) for Dublin City Council's only designated off-leash dog park, and Corkagh Park (Clondalkin) for space and a water fountain.

Quick-reference: Dublin's off-leash dog parks at a glance

1. Marlay Park, Rathfarnham

Address: Marlay Park House, Grange Rd, Rathfarnham, Dublin 16

Marlay was Ireland's first purpose-built dog park and is still one of the best-run enclosed spaces in the city, with separate small-dog and large-dog sections inside a hedged, gated area of the demesne. Bring your own water — bowls are provided but there's no tap — and expect it to be busy on weekends. A maximum of two dogs per adult is enforced. Note that the dog park has had recent closures for repairs, so it's worth checking Dún Laoghaire-Rathdown County Council's site before you travel.

2. Killiney Hill Park

Entrances: Main car park on Burton Road; pedestrian access from Ardburgh Road, Killiney Hill Road, Torca Road and Victoria Road

This is the one Dublin dog owners rave about most. It's fully off-leash, unfenced, and split into two main routes from the car park — one climbing through forest to the summit for views over Killiney Bay and the Dublin mountains, the other dropping through pine trees to Dalkey Quarry. There's no water fountain and no bins, so pack accordingly. The terrain includes tarmac paths and stone steps on the steeper sections, so it suits confident walkers and dogs with good recall.

3. St Anne's Park, Clontarf/Raheny

Dublin City Council manages dozens of parks, but St Anne's is the only one with a council-confirmed designated off-leash dog park. General off-lead hours run up to 11am and for the last hour before closing; outside those windows there's a dedicated fenced dog park beside the model car track (entrance off All Saints Road), split into a general area and a separate section for big dogs. Over an acre of woodland and undergrowth makes it a favourite for dogs who like to sniff and explore rather than just run laps.

4. Corkagh Park, Clondalkin

Address: Corkagh Park, Clondalkin, Dublin 22, D22 DR60

At 300 acres, Corkagh is one of the biggest green spaces in South Dublin, with a dedicated off-lead dog area about 500m into the park from the Camac Valley car park (N7 side). It has a water fountain and plenty of room to run — a good pick if Marlay is too crowded.

5. Cabinteely Park

Address: Old Bray Road, Cabinteely, Dublin 18

A 45-hectare park with a genuinely secure dog park: two entrances, each with a double-gate system, so an escapee dog is caught by the second gate before reaching the main park. Good option if your dog is a bolter.

6. Shanganagh Park, Shankill

A large, enclosed dog run right on the Irish Sea, popular with owners from Shankill, Bray and Greystones. Bowls are provided but bring your own water. The coastal setting makes it a nice add-on to a beach walk.

7. Griffeen Valley Park, Lucan

A 200-acre park in South Dublin County Council's area with a dedicated dog run open since 2012, set within the wider Lucan town park.

8. Phoenix Park (on-leash, honourable mention)

Europe's largest enclosed city park deserves a mention even though dogs must stay on-leash throughout — it's home to a herd of wild fallow deer that should never be approached off-lead. For sheer scale and variety of walking routes, it's still one of the best long walks in Dublin; just keep the lead on and stay alert around the deer.

Know the rules before you go

Dublin's four councils each run slightly different bye-laws:

• Dublin City Council allows off-leash time in specified windows (roughly 8–11am and again in the evening, varying by month) in most parks, with St Anne's the only park carrying a fully designated off-leash dog park.
• Dún Laoghaire-Rathdown designates specific dog parks within Cabinteely, Killiney Hill, Marlay and Shanganagh.
• South Dublin County Council runs dedicated off-lead areas at Corkagh and Griffeen Valley.
• Fingal County Council allows off-leash play in signposted areas within its nine parks (including Ardgillan, Malahide Demesne, Santry Demesne and St Catherine's Park), with local green spaces generally off-lead under control at all times.

On-the-spot fines for non-compliance can run from roughly €100–€150, so it pays to check the signage at each park.

Whichever park you choose, a clip-on scooper that lives on the lead means you're never caught out mid-walk. The Swoopet Leash Link clips straight onto retractable, rope or nylon leads and picks up on grass, gravel or muddy trail without you ever touching the bag — no-touch, no mess, no fuss, straight off the back of a full-speed Killiney Hill sprint. It's patented Irish design, sized for dogs up to 30kg.
