Overview
The mock-Norman bulk of Gosford Castle dominates the skyline here, and if you have watched Game of Thrones you have already seen it. The castle itself is a private residence, closed to visitors, but the 240 hectares of woodland and parkland around it are open daily, and the thing most people come for is the resident herd of red deer, usually visible from the Deer Park Trail.
Gosford sits on rolling drumlin country just east of Markethill in County Armagh, a mix of conifer and broadleaf woodland, open parkland and historic demesne grounds managed by Armagh City, Banbridge and Craigavon Borough Council. One thing worth knowing before you arrive: parking is no longer free. It is £5 for a car for the day, £2.90 for a motorbike, paid on arrival. Entry to the park itself costs nothing.
A landscape shaped by history
The estate’s roots reach back to the 17th century, when the Acheson family took the lands and built Clonkearney Manor; its foundations still sit near the millponds, a quiet marker of the demesne’s older life. The satirist Jonathan Swift, a friend of the Achesons, stayed on the estate and the park keeps that literary association.
In the 1800s the Second Earl of Gosford commissioned the mock-Norman Gosford Castle, one of the largest private houses in Ireland. It remains private today, but its silhouette still dominates the grounds and has stood in for filming on productions including Game of Thrones and The Frankenstein Chronicles.
The Department of Agriculture acquired the demesne in 1958 and opened it as a forest park. Older features survived the transition, among them millponds, a gatehouse, a Ha-Ha ditch and an arboretum with trees over 150 years old. A phased upgrade in recent years added new parking, better facilities and an expanded woodland playground while keeping the woodland’s character.
Trails and woodland routes
The park has 16 km of colour-coded, waymarked paths for walkers, runners, cyclists and horse-riders, signed with distances and difficulty at the junctions.
- Deer Park Trail – A gentle 1.2-mile loop past the red-deer herd, with open views across the drumlin slopes. This is the one to do if you only have time for a single walk.
- Castle Trail – A 1.8-mile circuit skirting the private castle boundary, through the arboretum and walled garden.
- Boundary Trail – A 3.4-mile route on forest tracks for a longer, quieter woodland walk.
- Cycling route – A dedicated 4-mile trail for road and mountain bikes. Off-road, battery-powered vehicles can be hired through All Out Trekking (ages 12+), set up so people of all abilities can reach the trails.
Trail maps are available at the main car park. The routes link up, so you can stitch together a loop of almost any length.
The adventure playground and family facilities
The park’s newer draw is its woodland adventure playground, a 3 km play area built around five large timber superstructures set into the natural terrain rather than dropped beside it. Younger children get gentle balance beams and low frames; older ones get rope bridges, zip lines and multi-level climbing towers. Surfaces are natural, and the layout keeps clear sightlines for parents on the benches nearby.
Wildlife and rare breeds
Beyond the playground, Gosford leans hard into rural heritage. The red-deer herd is the highlight, easily seen from the Deer Park Trail, and the park keeps one of Northern Ireland’s largest collections of rare-breed livestock, including traditional cattle, sheep and poultry. Information boards through the farmyard set out each breed and its place in Irish farming.

Getting there and what’s nearby
By car: Follow the A28 from Armagh town, then turn east onto the Ballynacarry Road (B78). Brown tourist signs lead to the Gosford Forest Park car park, just off the main demesne drive.
By public transport: Ulsterbus services run between Armagh and Newry; the nearest stop is in Markethill, roughly 5 km from the park entrance.
Nearby stops:
- A 10-minute drive north leads to Ballymoyer Woodland, another Forest Service site with historic ruins and quiet walking.
- Markethill village has independent cafés, a weekly market and easy parking for a pre- or post-walk stop.
Aim for early morning or late afternoon for the best chance of catching the deer moving through their enclosure, and pick up the trail map at the car park so you can extend beyond the main loops if the legs want more.
