Not somewhere we go often, Cavedale, but it is a great descent. It starts off with a fast open grassy singletrack section before turning rocky and fast, then it stops being fast and just gets rocky. The middle section is pretty hard to ride, steep and with sharp rocks all over the place, and water running down all over the place, through a series of narrow gullies. Nice.
This photo is from the bottom section where it goes through a kind of gully, apparently it all used to be a cave and the roof fell in or something. Anyway it all ends in Castleton which is an ideal place for a mid- or post-ride toasted teacake.
