Northern Ireland contains just 1.8m people – roughly a fifth of London's population. Indeed, the density of humans is so low that it can often feel as though you have the countryside to yourself; each path your own, save the scuttle of a red squirrel or the chirrup of a songbird.


With hundreds of miles of dramatic coastline, wild hills and mountains, magical forests and numerous beautiful rivers and lakes, Northern Ireland is a walker's paradise. We've put together a selection of the best walks in Northern Ireland, including route distance, duration and difficulty, as well as walking directions and maps.

Ballintoy and Portbraddan, County Antrim

Set in the midst of Antrim’s famous Causeway Coast, Ballintoy is a small village whose name translates as ‘town of the north’. The title is apt; Scotland’s Mull of Kintyre is visible on the Atlantic horizon.

The village jewel is its harbour, a time-honoured haven for fishing boats, constructed from limestone blocks and protected by a jumble of offshore stacks. So evocative is the location, it was chosen as the setting for the Iron Islands in HBO’s popular TV series Game of Thrones.

Yet long before its small-screen fame, this coastline was celebrated by walkers and naturalists. The signed Causeway Coast Way stretches off in both directions, providing 33 miles of superlative coastal hiking.

Less than two miles east along the path lies the unique and thrilling Carrick-a-Rede Rope Bridge. The route west towards Portbraddan is even better, and an out-and-back hike in this direction is not to be missed.

Severe weathering during the last ice age sculpted Slieve Binnian into the most distinctive peak in Northern Ireland's Mourne Mountains.

The scenic splendour of these mountains is well known. After all, this is the landscape that inspired CS Lewis to create Narnia. It’s also worth watching out for winter wildlife. The most commonly spotted wild mammal is the Irish hare, which can reach up to 48kph in full sprint. During particularly snowy winters, some upland hares change to a white or partially white coat.

The Rivers Glenariff and Inver have cut right through this spectacular steep-sided gorge – the Queen of the Glens.

These rivers can be lively and dramatic as they tumble over boulders and a series of three impressive waterfalls. But then they become suddenly calm and tranquil, flowing lazily through oak and beech woodland, sunlight streaming through the fresh new leaves.

The Mountains of Mourne loom large behind the resort town of Newcastle. The beaches and dunes here are superb for walking, but Newcastle’s jewel in the crown sits inland; a fulfilling circuit of two of the Mournes’ most notable summits, Slieve Bearnagh (739m) and Slieve Meelmore (682m).

Take on this tough upland walk, following a 100-year-old wall over peaks and cols through Northern Ireland’s Mountains of Mourne.

The River Shimna rises on the rutted slopes of the Mourne Mountains, gurgling over granite and heather before dropping into the shadowy depths of Tollymore Forest.

The slopes around the Shimna River are home to a remarkable number of tree species, including oak, beech, ash, birch, larch, Sitka spruce, yew and willow. Field maple, Himalayan cedar, eucalyptus, Douglas fir, Monterey pines, monkey puzzle and giant redwoods can also be found.

Climb through lush woodland along the Shimna River, past the Hermitage and on to Parnell's Bridge.

Situated 3.5 miles north-east of the coastal town of Newcastle in County Down, Murlough National Nature Reserve is a wildlife-watchers’ dream. Its range of habitats play host to a vast diversity of flora and fauna, and the long, sandy beach is the focal point of a fantastic walk, overlooked by the iconic Mourne Mountains.

Caves conjure mystical, murky thoughts of bats and boggarts, dragons and trolls. But step inside and your blood remembers. Your ancestors sheltered here, made fire here, chewed bones here. They would have gazed out from within, the dank, pitted walls of their refuge an unpolished frame for the rivers and woods and mountains beyond.

These doors into the earth – or out of it, depending on your aspect – can be found across the UK. Some are well-known, revered for their great atriums, jousting stalactites and archaeological remains; others are more elusive, secreted among quiet hills like dozing shadows wanting none of the fame.

One such hollow sits high within a rocky escarpment on the western slopes of the Annalong River valley in the Mourne Mountains. This six-mile, there-and-back-again walk takes you right to it, an exhilarating Boxing Day quest for friends and families with adventure in their veins.

The undeniably impressive Giant’s Causeway is Northern Ireland’s most popular tourist attraction. But step off the beaten track and you’ll be able to marvel at this coast’s geology, myths and breathtaking views in virtual solitude.

This six-mile walk starts east of the Giant’s Causeway at the shoreline hamlet of Portbradden, meaning ‘Port of the Salmon’. Historically a famous fishing spot, it still has a working slipway.

More unusual is the blue and white St Gobbans church. Known as Ireland’s smallest church, it is in fact a local man’s tribute to Gobban, a 7th-century Benedictine monk, whose actual church is a ruin half a mile away at Templastragh.

Founded in the 1970s by Wilfred Capper, the Ulster Way walking route circled all six counties of Northern Ireland. At 665 miles long, the original route proved awkward to maintain, but the best parts have now been re-packaged into 15 ‘quality sections’, or Waymarked Ways.

Together these provide signed walking routes across many of the best landscapes in the province. If you’d like a taster, the Mourne Way in County Down takes two days to complete and is a great place to start. Like all the routes, the trail is linear, fully signed and predominantly off-road.

Slemish is a name familiar to most inhabitants of Northern Ireland. Rising abruptly from its flat surrounds, the hill is an unmissable landmark of County Antrim.

Walkers know it as a short, steep climb that provides vast views, but there are so many stories associated with the hill, even those who have never seen it can recall its myths and legends.

Cape Town has Table Mountain, Edinburgh has Arthur’s Seat, and Belfast has Cave Hill. It’s one of those mandatory excursions and no visitor or local should spend long in the city without making the trip to the top.

Rising to 368m, the eastern slopes of Cave Hill are cut into a series of plunging cliffs. Some 3,000 years ago, the loftiest promontory was home to McArt’s Fort, a prehistoric ceremonial ring fort. Today it’s popularly known as Nelson’s Nose, a reference to its distinctive, face-like profile when viewed from the south.
