Three of us rode Dalbeattie on sunday morning/aft in perfect weather and trail conditions for a ride, one of the more demanding 7stanes trails to ride at pace and it’ll throw you off if you don’t pay attention, we rode the entire red route then some of the old XC stuff, widowmaker etc and as it was sunday there was no fear of possible forestry work.
As for the darkside stuff at mabie i can’t guarantee 100% accuracy but i guess it’s shut as the surface of the boardwalk may need treated to enable grip, chicken wire is horrible stuff and to be used as an extreme last resort imho.
