What kind of riding do you like and how far would you need to travel to get there?
Glentress has a red and blue grade downhill orientated xc circuits which are huge fun. The black is black more because of the distance rather than obstacles. I would say Kirroughtree red and black combo is better fun, BUT you can ride the black and then mix in the red and blue at Glentress to your heart’s delight.
It is a great facility, and you also have the very excellent Innerleithen which is much more DH orientated, including the mad XC route which combines with the DH towards the end.
In all, some fantastic fun rides to be had. I would always recommend people go there the once as the fun factor is huge.
