a good route is up carding mill valley, take the right when it fork after the stream, just before you pass where it says [p] on the map at the shooting box, take the right path to go straight through and over the carpark, that takes you onto the summit. Then down 8 (minton batch), the post marking minton batch has fallen over when I was there about 3 weeks ago so you may have trouble finding it if you haven’t been before. I can’t really describe where it is because there are no other terrain features, it’s just before a large sweeping corner to the right, before the gliding club.
At the bottom find your way back to carding mill and go up again, then some swoopy fast fun down to do 11, 12 and then 14. That’ll be about 3/4 hours or so. Have fun, wrap up warm 😉
