This week's question: Green & Blacks, yummy chocolate and 1:25,000 Rights of Ways?

Pick up any OS 1:25,000 map for England and Wales  - Scotland is  different - and you'll see the  Ordnance Survey uses different colours/markings for  different routes - paths (black dotted lines), public rights of way (green dotted/dashed lines), permitted paths (orange dotted/dashed lines),  tracks, roads, etc, etc. 

Next time you're poring over a map looking for your  next adventure - or plotting a route to download onto the GPS - look carefully at the  markings you're intending to follow. Look closely, and you'll see there are public rights of way paths (PRoW) and black paths in the same area, so what's the difference? 

For example, take a look the Lake District's Scafell Pike. It looks pretty confusing with all the marked paths approaching and crossing the summit area, and that's  just the map - minus the frequent zero visibility and endless boulders?!

The main mistake is to assume the PRoW paths are actually present on the ground. This isn't always the case.  It's the black paths that show where there is an actual route trodden by feet (and visible through aerial map photography). 

Take a closer look at the PRoW and you'll see they  sometimes randomly track over ground that's not always pleasant walking, as one  PRoW does on the NW approach to Scafell Pike from the head of Piers  Gill.  The black path on the map takes a route that is actually present on the  ground and keeps away from more dangerous crags.

When I have been working in the area, I have been shown maps where  people have plotted GPS routes using the green PRoWs only and have  subsequently got confused when they end up crossing pathless ground.  It's just  useful to know the differences between these two map markings - enough to  make your own route planning decisions.  Be aware - those rogue PRoWs are not  always what they seem!

Oh, and Green & Blacks dark orange chocolate is an all time,  hill time favourite!
