Dublin in Bloom: Five Gardens Worth a May Morning
Editor's Pick · Week of May 6, 2026
Four gardens and a cliff walk, while Dublin is in bloom.
May is the month Dubliners stop apologising for the weather. The buds are out on Stephen's Green, the gorse is loud yellow on the Howth headland, and the magnolia campbellii at Mount Usher is doing its annual show down in Wicklow. Our team gets the same question every May from friends flying in from far away: where would you go this weekend. Here are four answers, in order of distance from town.
Worth the Drive
1. Mount Usher Gardens, Wicklow
An hour south of the city, twenty acres of Robinsonian planting along the Vartry River, the kind of garden English visitors come to Ireland for. May is when the rhododendrons and magnolias take over; the magnolia campbellii by the suspension bridge is reason enough to make the trip. Bring a coat anyway. The river keeps the air a few degrees cooler than the car park suggests.
💡 Local tip. Drive if you can. The 133 bus runs from Dublin but slowly, and Mount Usher rewards an unhurried two hours and a slow lunch in Avoca next door.
📶 Signal note. Patchy in the valley itself, four bars again the moment you're back at the gate. Download offline maps before you set off.
DART Direct
2. Howth Cliff Walk
The DART drops you at the harbour and the loop starts twenty minutes later, up past the lighthouse. By mid-May the gorse is fully out, that almost violent yellow you can smell before you see, coconut and warm honey. Do the full purple loop if you have the legs (about two hours); the shorter green loop gives you the same headland views in half the time.
💡 Local tip. Go on a weekday morning if you can. Weekends fill up with families, and the cafés around the harbour have real queues by noon.
📶 Signal note. Five bars all the way along the path. Howth is one of the most reliably connected stretches of the east coast, so it's a fine spot to call home from a bench.

3. National Botanic Gardens, Glasnevin
Twenty minutes by bus from O'Connell Street, and somehow always quiet. The Victorian curvilinear glasshouses are the showpiece, but in May the rose garden is just starting to flower and the herbaceous borders are thickening up. There's a small café for tea and a slice of something. Allow two hours; you'll spend longer.
💡 Local tip. Pair it with Glasnevin Cemetery next door, where Michael Collins is buried. The guided tour runs at 11:30 most days and is genuinely good, not the dutiful kind.
📶 Signal note. Strong throughout the gardens and grounds. The glasshouses can drop a bar or two, but you'll never lose the line.
Wild Deer
4. Phoenix Park & Farmleigh
Larger than every royal park in London put together, with a herd of fallow deer that have lived here since the 1660s. In May the hawthorn comes into flower along the avenues, white and faintly almond-scented; the deer drift between the trees in the Fifteen Acres. Walk west to Farmleigh, the old Guinness estate, for the walled garden and a proper lunch in the Boathouse.
💡 Local tip. Hire a bike at the Parkgate Street entrance. The park is too big to do well on foot, and the loop past the Papal Cross to Farmleigh takes about an hour at a gentle pace.
📶 Signal note. Solid along the main avenues, weaker in the wooded sections near the Fifteen Acres. Worth a quick screenshot of the park map before you set off.
Why this week
Spring in Ireland moves north and inland in stages. By the first week of May, Wicklow's magnolias are at their peak, Howth's gorse is at its loudest, the Botanic borders are filling out, and the Phoenix Park hawthorn is just opening. By the end of the month it'll all have rolled past. Four weekends, four moments. There isn't a wrong order to do them in.
