It’s a good ride that, and yes the descent is well worth the landy track climb. Great area for riding. Best in country IMO due to terrain, weather, relative lack of midge and quieter trails (apart from Loch Muick area!)
PS is the descent off Morrone to Braemar worth the flog up the land rover track to the mast?
I was up there about this time last year and did it that way. If I was doing it again, I’d go up the descent route. There were too many times I found myself on the wrong lone on the descent. I reckon some familiarity would help. I imagine it would be much more fun once I knew all the best lines.
