it'll give you an idea of what each trail centre offers and will provide you a map of the trails. Some have bike mounted camera views of the trails, but to be honest I don't really think these do them justice.

Glentress will give you a bit of everything as it caters for all. My personal favoutites are Kirroughtree and Drumlanrig. If it's wood work your after try the black route at Maybe forest but be warned it is HARD CORE!

If I had to pick 1.....Kirroughtree.
