How to Read a Public Footpath Map: A Beginner's Guide to Rights of Way in England and Wales
A public footpath is an odd sort of thing: a legal right to walk across land that belongs to someone else. On paper it is a green dashed line. On the ground it might be a mown strip through a wheat field, a muddy gap beside a gate, or a track so faint you start to doubt it was ever there. The map settles the question — and, just as usefully, it tells you which lines are not yours to walk.
That distinction is the whole point. A green dashed line on an Ordnance Survey map is not a suggestion or a popular route; it is a legal right of way. A black dashed line might be a permissive path that the landowner can close. A faint line on the ground might be a desire path with no legal status at all. Learning to tell them apart is the difference between a confident walk and an awkward conversation at a farm gate.
Reading a rights of way map takes about half an hour of learning. It pays that back on every walk afterwards.
Start with the right map
For walking, an Ordnance Survey Explorer map at 1:25,000 is the one to buy. That scale — four centimetres to the kilometre — is detailed enough to show a stile, a footbridge, and the exact point where a path leaves a lane and crosses a field. The Landranger series at 1:50,000 marks rights of way too, and is fine for linking long distances by bridleway, but small features shrink into blobs you cannot plan around.
Every sheet carries its own key, and the key is the authority for what that sheet shows. Symbols have been adjusted between editions, and there are small differences between England, Wales and Scotland. Read it at the kitchen table, not in a gateway in the rain. If you are using a digital map, zoom in until the green dashes appear; many apps simplify the symbols at low zoom, which can make a bridleway look like a footpath and a permissive path look official.
It also helps to know what you are looking at. An OS map is a beautiful general-purpose map. A council's definitive map is the legal record. They usually agree, but they are not the same document.
The definitive map: the legal record
Every highway authority in England and Wales — usually a county council or unitary authority — keeps a definitive map and statement of public rights of way. This is the legal record of where footpaths, bridleways, restricted byways and byways open to all traffic run. It is the map that matters if a path is disputed, blocked or diverted.
Ordnance Survey maps are largely based on definitive maps, but they can lag behind changes. A path may have been diverted, extinguished or added by a legal order after your edition was printed. If you are planning a walk that depends on a single crucial link, or if you find a path blocked and want to check your rights, the council's definitive map is the place to look. Many councils publish it online, and the rights of way team can tell you about temporary closures and diversions.
For everyday walking, though, a current Explorer map is more than good enough. Just treat any unexpected locked gate or missing bridge as a prompt to check the definitive map, not as proof that the path does not exist.
The four kinds of right of way
Rights of way appear in green on Explorer maps, but the pattern of the dashes tells you what you are allowed to do. In England and Wales there are four types.
- Public footpath — walking only. Short green dashes. You can walk with a pram or a mobility aid where the ground allows, but cycling and horse riding are not permitted.
- Public bridleway — walkers, horse riders and cyclists. Shown by longer green dashes. You may also lead a horse. Cyclists must give way to walkers and horse riders, and in practice a bridleway can be just as muddy as a footpath.
- Restricted byway — walkers, horse riders, cyclists and horse-drawn vehicles. Shown by green dashes with a plus sign, or another symbol explained in the key. Motor vehicles are not allowed.
- Byway open to all traffic — often shortened to BOAT. Walkers, horse riders, cyclists, horse-drawn vehicles and motor vehicles may use it. Shown by green dashes with a plus sign, and distinguished in the key from a restricted byway. Many BOATs are unsurfaced tracks that are only practical for tractors, trail bikes or serious off-road vehicles.
The key on your map will show exactly how each type is drawn, because symbols can vary between editions. The important thing is not to memorise a single pattern but to check the key once and then trust the green lines.
Reading the line: dashes, waymarks and gates
Once you know the four types, the map becomes a set of instructions. A green dashed line that leaves a lane at a bend, crosses a stream, and meets a farm track is telling you where to look for a stile, a footbridge and a waymark. It is also telling you where not to go: if the line stops at a field boundary and there is no continuation, you have reached the end of that right of way.
Waymarks on the ground usually follow a simple colour code. Yellow arrows mark footpaths. Blue arrows mark bridleways. Red arrows mark byways open to all traffic, and purple arrows mark restricted byways. These colours are not universal in every detail, but they are a useful confirmation when the map and the mud are disagreeing.
Gates, stiles and bridges are worth noticing before you set out. A path shown crossing a wall may mean a stile, a gate or a gap. A path shown crossing a stream may mean a footbridge, a ford or stepping stones. On an Explorer map these details are usually marked, but they can be tiny. If you are walking with a dog, a child, a heavy pack or a mobility aid, a stile can turn an easy mile into a slow one. If you are riding a horse, a narrow footbridge or a kissing gate can be an impossible obstacle, which is one reason bridleways are often routed differently from footpaths.
What the map does not tell you
A rights of way map is a legal document, not a weather forecast, a farming report or a risk assessment. It will not tell you that the field has been ploughed and the path is a furrow of clods. It will not tell you that a bull is in the next field, that a bridge is closed for repairs, or that the river is in flood. It will not tell you that a permissive path has been closed for a shooting day, or that a path is so overgrown in July that you need long trousers and patience.
It also will not tell you about access land. On an Explorer map, open country and registered common land may be shown in a pale orange wash. That is land where you have a right of access on foot for recreation, separate from rights of way. It can be wonderful, but it comes with its own rules: dogs may be restricted, closures can apply, and you still need to navigate. A right of way is a line; access land is an area. Do not confuse the two.
Finally, the map will not tell you whether a path is easy. A green dashed line across a moor can be a lovely track or a bog with a talent for swallowing boots. A bridleway can be a wide stone track or a rutted stream of mud. The map gives you the legal shape of the walk. The ground gives you the experience.
Planning a walk with the map
If you are new to rights of way, a simple routine will keep you out of trouble.
- Choose a start and finish. Look for a village, a car park, a station or a bus stop. A circular route is easier to plan than a linear one if you do not want to arrange a lift.
- Trace the green lines. Use a highlighter or a pencil to mark your route. Check that every line you plan to walk is a public footpath, bridleway or byway, not a black or orange dashed path.
- Check the key. Confirm what the dashes mean on that sheet. Look for stiles, gates, footbridges, fords and steep ground.
- Estimate distance and time. A footpath mile can take twenty minutes on good ground and forty in mud, over stiles or uphill. Add time for photos, gates, map checks and sandwiches.
- Plan an escape route. If the weather turns or the path is blocked, is there a lane or a bridleway that gets you back sooner?
- Carry the map. A paper map does not run out of battery. If you use a phone, download the area for offline use and take a power bank.
- Tell someone where you are going. This is not map-reading, but it is the best safety habit in walking.
Once you have done this a few times, it becomes quick. You will start to see the landscape as a network of legal lines rather than a vague patch of countryside.
If the path is not where the map says it is
Even a current map can disagree with the ground. Crops grow, gates are moved, signs fall down, and landowners sometimes forget that a right of way crosses their land. If you lose the path, stop and look for waymarks, a stile, a gate or a worn line in the grass. Check the map's direction and the compass. Often the path is a few metres to one side of where you think it is.
If a footpath is ploughed and the line is not visible, you are generally allowed to walk around the edge of the field until you can rejoin it. If a gate is locked, look for a stile or a gap. If a path is deliberately blocked, do not climb a fence into a field of cattle or a private garden. Retrace your steps, use an alternative right of way, and report the obstruction to the local highway authority. They have a legal duty to keep public rights of way open and signposted.
The map is not the walk, but it is the argument you need when the walk is in doubt.
Reading a public footpath map is not about memorising symbols. It is about understanding that the countryside is crossed by thousands of legal lines, some ancient, some contested, some muddy, all walkable. Half an hour with the key will teach you to see them. After that, every walk starts with a better question: not "Can I go this way?" but "Which way am I entitled to go, and what will it be like when I get there?"
