Plan your visit

A story you walk through, not just a path

Fionn's Giant Adventure (the trail formerly known as the Giant's Lair) is a self-guided loop of just over a mile through Hawthorn Hill woodland at Slieve Gullion Forest Park. The whole thing is built as a quest: your children help the giant Fionn Mac Cumhaill outwit the trickster witch Cailleach Beara, with fairies and warriors marking the way. Look out for the carved fairy houses, the Giant's Table, Blue Belle Cottage and the dummy tree where little ones can say goodbye to their soother. Most families take about 40 minutes to walk it, then add a good while more for clambering, exploring and photos. It is genuinely free to do whenever the forest is open.

Free trail No booking needed Just over 1 mile, ~40 mins Fairy houses, dragons, giants Adventure Playpark beside it Cafe and toilets on site
Good to know before you go:

Adventure centres and trails across NI run seasonal guided sessions, family events and holiday activities, and the forest park itself hosts group tours and seasonal happenings through the year; the booked attractions have their own seasons, so check listings for dates.

The story

About this place

Slieve Gullion is the highest point in County Armagh and the heart of the Ring of Gullion, a ring-shaped band of hills formed from an ancient volcano around 60 million years ago. In local legend the mountain is not a mountain at all but a sleeping giant, and its summit holds a passage tomb and a lake tied to the tale of Fionn Mac Cumhaill and the witch Cailleach Beara, who tricked him into the cold water and turned him grey and old.

The story trail in the forest below grew out of that folklore. Described as one of the most ambitious children's arts projects commissioned in Northern Ireland, it turns the legend into a walkable living storybook of fairy houses, carved characters and art installations threaded through the woodland.

The trail sits within Slieve Gullion Forest Park alongside the Adventure Playpark, a scenic mountain drive and a courtyard with a cafe, all managed as part of the wider Mourne, Gullion and Strangford area.
