In reply to Thugitty Jugitty:
Two more tips...
1. Take your wellies!! Everywhere is absolutely sodden at the moment
2. If you want to avoid the somewhat "enthusiastic" parking charges at the YSP, i.e.
All day: £12.00 / 1–2 Hours: £6.50 / Up to 1 hour: £3.50
park at High Hoyland (and have a pint in the Cherry Tree) and walk north down the road past the church, then take the footpath at GR SE 275 114 north east on the Barnsley Boundary Walk, which takes you right into the middle of the park. You can also park on the roadside next the end of the path. From High Hoyland it's just a short drive (or even a walk) down through Cannon Hall to the Spencer Arms.
