Hi David,
You would be best parking at the bottom of the large bank at Oakamoor, in the car park with the grassy field near there. As you come into Oakamoor from Cheadle, you drop down a huge bank, it winds round and as you reach the bottom turn right, and the parking area is on your left 100m down or so. From there walk over the grassy area, cross the bridge and follow the track to your right, following the left of the river, this runs all the way to Denstone, and Ramblers Retreat is nicely placed 1/2 way along for a stop to have coffee etc. The area around Ramblers is Dimmingsdale, plenty of Pied Flys around there, and other stuff, at the moment that is.
On the N Staffs moors you could get Ring Ouzel, S E Owl, Merlin and stuff like that, but you'd have to be lucky to get all, and sometimes even any of them! Also i reccommend Seven Springs on the Chase - or just any of the chase, although it might be a bit too far away. You could perhaps visit Shuboruogh whilst you're there, and see the infamous Belted Kingfisher spot!!!! Also in that area you've got Blithfield Reservoir, and nearer Stoke, Park Hall CP, which is good for L E Owls.
Hope this helps
Dan
