How long it really is
We measure Llŷn Coastal Path at 162.5 km (101 miles), computed by walking the OpenStreetMap route geometry point by point .
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 38 h 47 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 Wales, so one access regime applies along its length.
Wales
Conditional Right to roam: Right to roam only on mapped CRoW open access land.
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.
The route in day stages
Llŷn Coastal Path cut into 8 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.

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.
