To get to the Pecket Well descents, ride up the A6033 out of Hebden to Pecket Well (I’m sure there are better ways to get there, but I just honk up the road). Look out for a BW signposted off to the left (if you’ve come UP the hill) – it splits not far down the track, these are the 2 Pecket Well descents. You can ride down 1 and push back up to ride down the other, or figure out a loop to incorporate both.
If you take the RH fork, this will spit you at at Hardcastle Crags lower car park – when you hit the road, go straight across the bridge in front of you (ish!) then bear left and you’ll see the Blue Pig pub which is at the bottom of the Blue Pig descent.
I don’t know what state any of the trails are in at the moment as I haven’t been over that way for a while. Pop in to Blazing Saddles and ask.
