At the weekend, we had a great cycle round some of the Loch Leven trail - even my Wii-loving 6 year old really enjoyed trying out his new Ridgeback... This route was a bit of a discovery for us - we normally hit the prom at Silverknowes or the heavily-oversubscribed Flotterstone road...
Any other suggestions for child-friendly routes like this, reasonably near the capital i.e. driveable? I mean routes that are totally traffic-free and not too hilly! (I also normally have the other sprog in a front-loading bike seat which limits how rough the trail can be - but he won't be there forever..)
