Hillside is the easyest access round the valley as the owner will allow you to back the car right upto the water if you ask and the bank is flat and very well maintained.
Out of Rawtenstall head for Burnley and out through Crawshaw Booth.
As you gain altitude the fishery is to your left. it is sighnposted from the main road and easy to find.
Its not the easyest to catch on but if all fails find the corner with the spring/pipe flowing into it as all the new fish hang around here and just about any wet fly dropped amongst them will save a blank.
