Starting at Tansley just off the A615 park at either the Tansley Tavern pub car park or on church street Tansley just the second right coming from Alfreton heading towards Matlock. Starting from the car park walk down the main road towards Matlock and take your second right onto Church street Tansley and walk up Church street until you turn left onto the road The Knoll follow the road around and to the end as you walk round you can see the woods up at the top of the hill and a single house called Oakedge farm. This is where you are heading towards, as you walk along the Knoll you pass a footpath labelled Lumsdale and this is the path you will return on and the walk can be done in reverse to shorten the walk and come out at the bottom of the waterfall you could turn left here and walk straight to the waterfall and bottom of the old mill.
As you get to the end of the Knoll you are provided with a choice of paths take the road around to your left over the river and walk up the hill and up Oakedge lane heading towards the farm house and the start of the woods.
At the top of the Lane turn right up into the woods there are two paths do not take the first one on your right but take the second one that goes straight upwards slightly further on . As you walk up the path you will pass an old Quarry on your right hand side used for quarrying mill stone, just after this take the path around to your left and notice how the path falls away to you left hand side and looking out you can see Riber Castle on a clear day.
Follow the path along the edge through the trees and after a while you are presented with two paths one sharply up on your right and another that crosses over a small wall and follows along a fence. Take the lower path along the fence line and follow to the end.
