Best accessed from the top of ladies combe at the end of holford combe. Where there's a clearing it the top with a tree in the middle of a grassy area, go through a gap in a bank and follow any single track down the hillside to the road. Cross the road and you're into the BC descent, after about 120m there's a fallen tree to hop over, with another one to jump over(there's a soil ramp over it), just after that go left around a further fallen tree then rejoin the obvious path. Stick to all the left hand lines where you see them, staying out of the leafy ditch as much as possible but you will need to get in there on occasions.
At the end of one section of ditch as you graze past a holly tree, there's a slight booster, just after that cut through the earth bank and drop into a dried up stream bed(by an old metal Safe(from a nearby PO robbed about 20 years back)Follow this stream bed along the valley floor in the direction whence you came, to get back up to the road crossing for the best way back up. Or to get to Stowey you can continue down the stream bed. Beware though as it becomes extremely boggy and probably unridable down there for a good way. My preferred route from there to get to stowey is as follows.
From the safe in the stream bed, continue down and under a fallen tree taking the next left hand gap in the earth bank back up onto the trail you'd come down on.(it's not rideable up there for a section due to a hole on the trail and a low hanging tree) Follow the trail along and you'll begin to climb again, after a hundred metres or so, and before you ride under some dense Rhoddies turn right on a very vague leafy single track traversing the hillside heading east. After some 50m or so, you'll come to an area of dense holly bushes, here drop down the hill and slalom said bushes down the obvious lower track. There will be a gate to you left along the track. Go through it and follow it, at a crossing by a house continue straight on. After a muddy section you'll see a stream to the right and steps on the left, you can ride them if committed and keeping to the left side of them. Follow path to the end and turn left at the road into Stowey.
Knottie. Yes i really like this trail and after doing i, i'd ride up and do CB after it gaining my and extra descent. BC descent and climb is only a 30minute max section so a nice inclusion to a loop. IMO
