Barnsley train and Bus station (together) 3 min walk as they are both in the town centre, ask for McDonalds in the town (stay on the flat, then up by the post office and you'll see the YM on the corner, but the camping is along Blucher St to the back of the YM- Community Hall, will be open Fri 5.30pm or give me a ring on 01226 284927
On Leeds Sheff line or if you go to Wakefield, may need to change from Westgate to Kirkgate, could get London bus
