How long it really is
We measure Mourne Wall Challenge at 30.8 km (19.1 miles), computed by walking the OpenStreetMap route geometry point by point . The route is tagged in OpenStreetMap as 36; where that differs from our figure, the difference is usually alternative sections, spurs, or a published distance that rounds.
This is horizontal distance only. Our trail dataset carries no elevation profile, so we will not quote a total climb or a confident walking time — on hill routes ascent can add hours a day. A flat-ground pace gives roughly 6 h 54 min of walking for the whole route, which is a floor, not an estimate. Add your own ascent figure in the walking-time calculator for something usable.
Access rights along the way
The route stays within Northern Ireland, so one access regime applies along its length.
Northern Ireland
Permission needed Right to roam: No general right to roam.
Permission needed Wild camping: Permission needed everywhere.
A waymarked route is a route you may walk — it does not follow that you may camp beside it, leave it, or take a dog on it. Long-distance paths cross farmland, estates and access land in turn, and byelaws and seasonal restrictions override the general position. This is general information, not legal advice. Check a specific spot with the access checker.
Summits on and beside the route
Listed hills from our hill dataset whose summit lies within 2.5 km of the line — 8 of them within 350 m, so effectively on the route itself. Distances are measured from the nearest point of the path, not from a trailhead.

The route in day stages
Mourne Wall Challenge cut into 2 stages of roughly 20 km, measured along the line itself. These are equal-distance splits computed from the geometry, not an official itinerary — they will not always land on a village, a bunkhouse or a station, and the real day you walk should be set by where you can sleep.
| Stage | Distance | Cumulative | Starts near | Ends near | Flat-ground time |
|---|---|---|---|---|---|
| 1 | 20.2 km | 20.2 km | SB 4245 7842 | SB 4288 8405 | 4 h 27 min |
| 2 | 10.2 km | 30.4 km | SB 4288 8405 | SB 4245 7842 | 2 h 15 min |
Positions are 8-figure (100 m) OS grid references for points on the line, computed from WGS84 coordinates. Flat-ground times are Naismith at 5 km/h with a 6 min/hour rest allowance and no ascent — add the climb in the walking-time calculator before you plan around them.
