I'm just back from it for my stag trip.
Amazing journey, fantastic beers and a real experience! If you need anything at all, my brother did up an incredible itinerary.
What we did was actually went from Leeds right the way out to Satlybridge to 'The Buffet Bar' - which as it happens was the highlight of the day. Excellent spot. We worked our way back into Leeds then.
Organise a head of time to get to the Riverhead Brewery Tap in Marsden at a time when they're serving food and giving tours...well worth it!
