In reply to steveb2006:
> Far Eastern Peak Barbrook Pool SK 276 761 is a nice spot for a swim and combine with a walk over White Edge. Muddy bottom but pleasant moorland spot. Could park by Ramsley Reservoir SK288 746 but you can just park on A621 as well to make a shorter walk.
To make it a longer walk and avoid some of the busy-ness closer to White Edge and the Longshaw estate, you could nominate the Royal Oak as the pub and park in Millthorpe. There's a bit of space at the end of Millthorpe Lane at SK318765 (lat/long 53.2840, -1.5252).
From there go South on Mill Lane (the minor road marked as a dead end) - cross the ford at Millthorpe Brook, ignore the footpath coming in from the right just past the houses and then where the tarmac ends it sort of splits into three rights of way. (Bridleway up the lane between the hedges, footpath either side.) The footpath to the right (over two stiles just at the end of the farm driveway) goes across fields to a lovely path up through the woods around Pingle Dike. If the stiles were a pain in the arse with the dog it's also nice to go straight up the lane towards Johnnygate.
From the top of the hill where you onto the road after skirting round Moorhall Farm there's about a mile of tarmac (it's a nice quiet road though, with pleasant views) to Shillito Wood, and a bit more to Ramsley Reservoir. (Disused - like the big Barbrook Reservoir it's been drained and had a big "V" cut out of the dam.)
As above from there, perhaps find the ruins of Ramsley House, visit the little Barbrook Reservoir, White Edge, possibly even Froggatt/Curbar etc..
Then from the big Barbrook (ex) reservoir, there are several routes you can take across access land down towards Smeekley Wood. There are some delightful little paths that follow Millthorpe Brook through the woods there.
The main road from Millthorpe up to Owler Bar is nasty to walk on though - twisty, narrow and quite busy. (With some impatient drivers who won't give you enough space.) So with a dog and a child I'd avoid that bit and go up the hill and across Fox Lane, taking the footpath over to Unthank Hall, and the path going East from the bend on Unthank Lane is the same one you'd have passed on the way out of Millthorpe at the start.
