Close to me also but I would rather drive for two hours to go somewhere better tbh.
Firstly its very short and due to its location,the north facing side of the Campsie hills it never seems to get warm or dry out ever.
I appreciate that folk have put in a lot of effort to do this but it just doesnt do it for me or anyone I know who has used it.
A better place to go in my opinion and especially for a first timer is the forest tracks around Aberfoyle which as you know no doubt isnt that far away.Several easy routes to choose from and a few that are a bit more demanding.
Although I can see snow on top of the Campsies out of my window right now so there may well be some at Aberfoyle at the minute as well.
