You are generally either going up or down usually at about 10 to 15%. I’ll usually do 10 to 15 miles with about 2750 to 3750 feet of climbing.
The best descents are.
Oxencraig to Back o Benacchie
Millstone’s saddle, North or South.
Mither Tap to Rowantree car park.
The Gordon Way from Oxencraig.
Southern path from Mither Tap
Northern path from Mither Tap
Southern path from Millstone Hill summit.
They are probably in a rough order of how difficult they are. They are mostly walkers paths so expect water bars and stone staircase type of stuff.
I generally head out from any of the main car parks (visitors centre, Rowantree, Don View or Back o Bennachie) and link any of these descents.
