The high point of the Ring of Gullion AONB in south Armagh — dark rural sky, but the forest drive has gate hours and the summit is a real hike, so plan around access.
Slieve Gullion Summit Stargazing — The high point of the Ring of Gullion AONB in south Armagh — dark rural sky, but the forest drive has gate hours and the summit is a real hike, so plan around access.
What you'll see: Dark rural sky on clear nights, with the Milky Way possible on genuinely dark, moonless nights, plus planets and seasonal meteor showers. It depends on cloud and moon — nothing is guaranteed.
Getting there: Slieve Gullion Forest Park near Killeavy, south of Newry, County Armagh, within the Ring of Gullion AONB.
When to go: Clear, moonless nights, worked around the park gate hours — in winter the park may close before full dark, so use the surrounding roads.
Facilities: The forest park has a courtyard centre and daytime facilities, but these follow the park's opening hours and are not there for night visits. On the open mountain and roads there are none.
Cost: Free.
Good to know: The forest park gates close in the evening (about 9pm summer, 5pm or dusk winter — confirm current hours) so you can be locked in if you drive up late. The summit is unlit and a real climb. Bring a torch (a red light saves your night vision), warm layers and sturdy boots, and tell someone where you are.
Plan your visit
Mind the gate hours
Slieve Gullion Forest Park is open seven days a week but the gates close in the evening — around 9pm in summer and 5pm, or dusk, in winter. That matters for stargazing, because in the darker winter months the park may already be shut by the time the sky is properly dark. Check the current park hours before you plan a night up the forest drive, and never risk being locked in behind the gate. For a late, dark-sky session, base yourself on the public roads around the mountain instead.

Good to know before you go:
