We usually include a more moderate one or two on our XC/trail outings; there are so many lines I get confused which is which. If you can handle a trail bike on DH trails, I’m sure you’ll be fine. Go up to Triscombe CP and follow your nose (or someone else).
I was up there walking the dog at teatime, very dry and dusty. The postcode for the Blue Ball pub at the bottom of the hill (quarry side) is TA4 3HE the car park is up the top of the hill. The road up past the quarry is a bit rough and steep but driveable.
