Sorry guys misread this thread in a bit of a hurry earlier.
To try and clarify a couple of points:
Bunton Hush is quite a steep rocky gully from the moonscape into the Gyll, we ride it loads it's a fantastic bit of rocky singletrack with proper consequences!That drops you down to a finger post with four arrows on it. From there you can head up the valley and drop down to the stone bridge and head back to Gunnerside on the West side of the Ghyll. Another option from the finger post is to head south along b/w on East side of valley under Winterings Scarr. The later is a better option as 'esselgruntfuttock' says
Blakethwaite Ruins if that's the stuff up top near the dam I wouldn't bother
There is 5 or 6 different ways to drop into the ghyll from the moonscape on top. It's all good but if the cloud is down it is sooo easy to get lost.
If anyone wants advice call in to Dales Bike Centre, Fremington on your way. The trails have drained really well since all the rain we had 2 weeks ago. There is mud and bog around if you look hard for it but there is sooo much to that is good riding.
Hope that helps
