er, I just use an Ordnance Survey map. Loads of trails on any of them – it is Scotland, after all.
Yawn! Dull elitist claptrap. You might be too clever for trail centres, but they've introduced thousands of people to a fantastic sport/activity/hobby/pastime. Not everyone has a stunning network of trails on their doorstep. X %age of Scotland's population may live within an hour of a forest, but doesn't mean that the forest is available to them as a recreational resource. Just f+ckloads of commercial crop and a few forest roads.
From what I've seen, I think Scotland's biggest land manager has made a right arse out of things, but you can't deny that the trail centres developed over the past ten(?) years are a good thing.
Anyhoo, all bollocks really. There'll be no new meaningful singletrack built in FCS managed forests until there's a change of regime there…
