Parks & Gardens in County Antrim

Four of these ten sit in Belfast or on its edge, and three of them could be done in a single day without leaving the city. Belfast Botanic Gardens is free, 28 acres in the Queen’s Quarter, and the reason to go is the pair of glasshouses: Charles Lanyon’s curvilinear Palm House, and the sunken Tropical Ravine reopened in 2018. Stormont Estate, 224 acres on the eastern side, suits a long walk up the avenue, the Saturday parkrun or the Mo Mowlam play park. The Titanic Memorial Garden is smaller and quieter, in the City Hall grounds, where the Belfast List names all 1,512 who died.

Colin Glen, on the western edge, is a different kind of day: 200 acres of old linen-mill woodland with an alpine coaster and a zipline launching from the Mountain Entrance, and calmer river walks at the River Entrance.

The rest are a drive. Glenariff and Glendun are two of the Nine Glens on the north-east side of the county; Glenariff’s gorge boardwalk passes three waterfalls and is at its fullest after rain, while Glendun is the deeper and emptier of the two, with the 1830s viaduct spanning it. Mid and north Antrim hold the town gardens, at Ballymena, Broughshane, Ballymoney and the Carrickfergus waterfront.

Where to start

  1. Belfast Botanic Gardens Belfast

    A free Victorian park in the Queen's Quarter whose curvilinear Palm House predates the one at Kew, with the restored Tropical Ravine sunk beside it.

  2. Colin Glen – Belfast's adventure park Stewartstown

    Two hundred acres of old linen-mill woodland on Belfast's western edge, holding an alpine coaster, a long zipline and quieter colour-coded river walks.

  3. Glenariff – The Queen of the Glens Glenariff

    The largest of the Nine Glens, with a boardwalk through the river gorge past three waterfalls and longer trails climbing onto the Garron Plateau.

  4. Glendun Glen – River, Forest, Viaduct

    The deepest of the glens, where the peat-stained River Dun runs through old woodland beneath the three-arch viaduct built in the 1830s.

  5. Stormont Estate – Belfast's parliament park Belfast

    A free 224-acre park on Belfast's eastern edge, with the avenue up to Parliament Buildings, a Saturday parkrun and an inclusive play park.

Colin Glen – Belfast's adventure park

Stewartstown, antrim

Colin Glen is 200 acres of old linen-mill woodland on the western edge of Belfast, run by a community trust. It holds Ireland’s first Alpine Coaster, the Black Bull Run, its longest zipline, and its only official Gruffalo Trail, alongside colour-coded river and hill walks. The River Entrance is the quiet, family end; the Mountain Entrance is where the thrill rides launch.

Stormont Estate – Belfast's parliament park

Belfast, antrim

Stormont Estate is a free 224-acre park on the eastern edge of Belfast, bought in 1921 for Northern Ireland's new parliament and now holder of a 12th straight Green Flag. Walk the avenue up to Parliament Buildings, run the Saturday parkrun, or bring children to the Mo Mowlam inclusive play park; WWII barrage-balloon anchors still sit on the lawns.

Questions people ask

Which of these is best with young children?
Colin Glen has Ireland's only official Gruffalo Trail, and its River Entrance is the quieter family end. Marine Gardens in Carrickfergus has a pirate-themed, wheelchair-friendly playground that reopened in 2024. Stormont Estate has the Mo Mowlam inclusive play park and is free to enter.
Which ones can I reach without a car?
Belfast Botanic Gardens, the Titanic Memorial Garden at City Hall and Stormont Estate are all in Belfast, and Colin Glen sits on its western edge. People's Park is a short walk from Ballymena town centre. Glenariff, Glendun and Broughshane really need a drive.
Where are the two glens on this list?
Glenariff and Glendun both lie among the Nine Glens on the north-east side of the county. Glenariff is the largest, built around a wooded river gorge; Glendun is the deepest, running down to the Atlantic, with the three-arch Glendun Viaduct crossing above it.
When is the best time to walk the Glenariff waterfall trail?
The three waterfalls on the gorge boardwalk carry most water after heavy rain and through the wetter months, so autumn, winter and spring show them at their strongest. Summer is easier underfoot, and the nature reserve's mosses and ferns stay green year round.
Is there anywhere here for sport or a run?
Stormont Estate hosts a Saturday parkrun across its 224 acres. People's Park in Ballymena has four floodlit astroturf tennis courts that are free and need no booking. Colin Glen's colour-coded river and hill walks cover the longer distances on foot.
