Followed madfrankies advice (above) but parked outside a wonderful white cottage on Ballard Road. Did not have to proceed as far as wood, Through the gate and follow the green road. Its a nice route and not strenuous. A good one to get you back in the game after seasonal excess. The surrounding countryside make this worth the trek with good views to Dundalk Bay. Also worth the trek to see South Armagh. Linkback: https://mountainviews.ie/summit/322/comment/3501/

Most people start at the carpark high up the mountain. This car park can hold a minibus or four and is a good start point for a quick walk to the summit, taking around thirty to forty minutes. If you start from the bottom beside the centre, it is a longer walk up through the forest then some exposed ground along a road, but not very exciting and to be avoided really. Good for a quick afternoon walk. The summit is easy to reach over some loose scree, and is just above a plateau with a number of lakes. Can be treacherous in the wrong sort of weather, as we found while doing a scout orienteering competition in the fog. Linkback: https://mountainviews.ie/summit/322/comment/886/

Track 2508 Went up with 2 friends who are hell bent on doing the county high points for Ireland - and I would never have thought of tackling Slieve Gullion if if wasn't the county highpoint for Armagh. It's the closest point in the North - about 90km from Harolds Cross in Dublin. Take the first turn inside the border - going towards Jonesborough - famous for it's market in the 80's and it was still there when we passed by on a Sunday.

Starting from the Slieve Gullion Forest Park car park. There's a nice cafe there in the Slieve Gullion Courtyard Centre.

WALK DIRECTIONS (Ring of Gullion Way/RGW blue arrows): From top left corner of car park (OS ref J 040196 A), left up path through trees. In ¼ mile join Forest Drive (038191 B), up slope, then level, for ¼ mile to RGW post on left (035190 C). Right up drive, past metal barrier; left uphill for 1½ miles to car park (018200 D). Beyond picnic table, right at white post, steeply uphill to South Cairn on Slieve Gullion summit (025203 E). There's a 3000 year old tomb on top which you can go down into- and a much more recent dugout up on top which the British Army used during the Troubles.

On the way back you pass the Lake of Sorrows which is Cailleach Beara's house - she turned Fionn Mac Cumhaill an old man when he dived into the Lake of Sorrows to for her golden ring.
Head towards the North Cairn (021211 F); then aim north for Sturgan Mountain (left of Cam Lough), then white house between you and lake. Path divides by grassy 'lawn' with boulder beyond; right here, aiming for house. Through gate, down to road (025230 G). Right along road for 3 miles, passing Killevy Old Church (040221 H) and Clonlum Cairn (047206 I),
Cairn is nicely hidden with bushes and stuff - well worth crossing the field for it.

About another km to the Slieve Gullion Forest Park (046199 J). Linkback: https://mountainviews.ie/summit/322/comment/15224/
