Can you follow a path just because it's on the map? What route data does and doesn't tell you
A path on your map or in your app isn't permission to follow it. Here's how to read map lines, hunting notices in Wallonia, GIPOD notices in Flanders and climbing figures on route pages, and how to turn them into a short, useful check before you leave.

No, a path showing up on your map or in your app doesn't mean you're allowed to follow it. A map shows where a path lies. Whether you can use it on your day and with your sport depends on the rules, the manager and the signs on site. If you know that difference, you get far more out of maps and route data, and you won't find yourself facing a closed forest track with ten kilometres still to go.
In Belgium this plays out in two ways. In Wallonia, forest rules and hunting can close a path, temporarily or for good. In Flanders, roadworks and events sometimes send you on a detour. A good route check therefore matches the right source to the right question, the right place and the right day. That sounds like work, but it's quick once you know what each source is good for.
Why a line on the map isn't permission
A map line tells you where someone drew a path, not whether you may use it. OpenStreetMap (OSM) is a map that users draw together, a bit like an encyclopedia that anyone can add to. The OpenStreetMap Foundation doesn't check every edit in advance and doesn't guarantee that the data is complete or correct. Say someone drew a path along a meadow years ago, and a fence has since gone up. On your screen, that path looks just as inviting as the forest track next to it. [1]
Access is arranged elsewhere. In Walloon forests, whether you may walk or cycle somewhere depends on the rules and restrictions in force. Those rules apply even if your map or app says nothing about them. So read a map like a street plan, and look up the access rules with the authority that sets them. [2]
So what does a map tell you?
A map is strong on position: where your route runs, which junctions you'll meet and how paths connect. That helps you spot your turn along the way and see in advance where an alternative is possible. For access, temporary disruption and climbing metres, you need other sources. The table puts them side by side, so you open the right source for each question.
| Source | Tells you | Doesn't tell you |
|---|---|---|
| Map line (for example OSM) | Where a path lies and how it connects | Whether you may go there and whether the data is complete and correct |
| ChasseOnWeb (Wallonia) | Hunting areas and battue dates | What the signs on site say, which still apply |
| GIPOD (Flanders) | Roadworks, events and disruption on public land | That a place with no notice is clear |
| A provider's route page | Distance, climbing metres and points to watch for for that one route | Figures for your own adjusted line |
| Sign on site | What applies there, at that moment | What happens further along your route |
Notices apply to one place and one day
A notice is only useful if it covers your stretch and your departure day. In Wallonia, ChasseOnWeb publishes the hunting areas and the dates of battues, which are drive hunts where game is driven through the woods. The signs on the ground still apply, even if you found nothing online. In Flanders, GIPOD collects information on roadworks, events and disruption on public land. Hold each notice up against the place and the hour you'll pass through, because a shaded area on a different day says nothing about your outing. [3] [4]
No result only means you didn't find a matching notice there. Say you want to walk along a cycle route in Flanders on Saturday and find nothing in GIPOD. Then you know that no notice came up for that place. You still don't know whether the path itself is open and passable. Turn an empty result into a follow-up question, for example to the manager, instead of a green light. [4]
Why two route figures don't match
It's best to read climbing metres together with the line and the method behind them. D+ is the total of all the bits of climbing on your route, like counting every step you take up a staircase. Take the green-marked ExtraTrail route in Jalhay, on the edge of the High Fens. The route page gives 12 km and 310 metres of positive elevation, with an estimated time of 1 to 2.5 hours. Those are the values of that one route page, not of every route with a similar name. [5]
The same page also gives information that really changes your planning. Between km 8 and 8.5 there's an especially muddy stretch where you can slip. Around km 8.75 you can shorten the route to 10 km. Points like these are often more valuable than the elevation figure itself: they tell you where you'll slow down and where you have a way out. [5]
By default, RouteRadar calculates the elevation profile with a terrain model along your GPX line, the file holding the line of your route. After a quality check, RouteRadar can also use the elevations from your own GPX. That's our own calculation method, and another app or route page may calculate differently. If your profile shows a different D+ from the route page, first check whether the start point, the line followed and the direction of travel match. A difference doesn't in itself prove that either figure is wrong.
Which check suits you?
Situation → what you check
- First time out → pick a marked route with its own route page; the points to watch for there show where to be careful.
- Drew your own GPX → check the stretches you drew yourself and the links between two known routes in particular: no provider stands behind those.
- By train or bus → check the stretch from the stop to the start, and back, separately, because it usually isn't part of the marked route.
- Restarting after a break or prefer to take it easy → pick a route with a shortcut option and plan for the slow end of the estimated time.
How to tackle a first check
Say you're planning the green route in Jalhay for Saturday. You open the route page and note the muddy stretch and the spot where you can shorten the route. Then you look in ChasseOnWeb to see whether a battue is planned nearby that day. You compare your GPX with the marked line, so you know which figures belong to which line. If one stretch stays unclear, you ask the manager about exactly that stretch: between which two junctions, with which sport and on which day. That way you get a targeted answer instead of a general statement about the whole area. [3] [5]
Your check in five steps
- Write down which sport and which departure day you're checking.
- For each question, open the right source: map for position, notices for your day, route page for figures and points to watch for.
- When a notice is relevant, keep the original page, with place and period.
- Mark the stretches you drew yourself and the links separately from the marked route.
- Leave an open question open and, if need be, choose a different route.
Frequently asked questions
My app reports nothing, but there's a prohibition sign on site. What applies?
The sign wins. Your app only shows what was in the data it used, while the sign says what applies there, at that moment. Choose another way and adjust your route afterwards.
Can I fix a mistake on the map myself?
OSM is built from user contributions, so you can add or improve things too. Only draw what you saw yourself on site, and remember that a drawn path doesn't become an access rule, even after your edit.
Do I have to check every source for a short outing nearby?
No, work through the questions that make a difference for your route. If you're walking known paths in Flanders, GIPOD is often the most important. If you're heading into the forest in Wallonia, look first at the forest rules and the hunting notices.
This week, pick a route you've wanted to do for a long time and turn it into a five-minute check: the map for position, the notices for your day and the route page for the figures. Load your GPX into RouteRadar, read the points to watch for and set off with a plan that has a way out too.
