Navigation - Which path should I take?
There is an extremely high standard of mapping available in the UK and we
are extremely lucky to be able to use highly detailed Ordnance Survey maps
wherever we go. With practice these maps can tell us everything we need to
know to get ourselves from A to B safely. However one area that often seems
to cause confusion is the different ways paths are marked on Ordnance Survey
maps; a better knowledge of when each symbol is used will soon improve your
ability to find your way across the hills.
On a 1:25,000 Ordnance Survey map public rights of way in England and Wales
are marked with green dashes (short dashes for footpaths and long for
bridleways) but it is very important to remember that this means only that
there is an ancient common law right to pass along this route at all times.
It does not mean that you will necessarily be able to see the path and be
able to follow it. Definitive maps of the rights of way were drawn up by
county councils in the 1950s and many of these paths are now long since
disused and overgrown and, even in good visibility, can be difficult or
impossible to find.
Other paths which are not designated rights of way are marked on the
Ordnance Survey maps as short black dashes. If these paths are within the
newly designated access land you are perfectly within your rights to walk
along them. These paths are marked on the map because at the time of the
aerial survey used to create this map they were visible on the ground; they
have usually been made by thousands of feet walking along the same line.
They are often the most direct route from summit to summit or from the
summit to the valley because they have been created by humans going where
they want to go.
For hill walkers the problem with this system is that the green dashes of
the public highways stand out clearly on the map and often give the
impression that these paths are more important or bigger than the black
dashed paths, however often the opposite is true. You should never assume
that a path is going to be easy or even possible to find but this is
particularly true for the public rights of way. A black dashed line on the
other hand tells you that particular path was visible on the ground at the
time of making the map and chances are it still is.
When following any path you should continually compare the map to the ground
you are covering to make sure the path really is going the same way as the
dashes on the map. Paths change over time and could have changed since your
map was last updated. Do not rely on paths and always be prepared to use a
compass if the path you are following disappears or goes off in the wrong
direction.
