Minning Low (keep an eye out for it on the horizon....)
Nine Stones Close/Robins Hood's Stride (and the hill fort behind the farm)
If you are that way and have the time, you can do a circular walk from Winster taking in Stanton Moor and the sites (Andle Stone, Nine Ladies etc. etc.) and then heading back towards Elton and Nine Stones Close which is an absolute gem, and Robin Hood's Stride, very much the prototypical Copey Hill Altar.
Arbor Low is important to see if you haven't seen it.
The Bullring is equally impressive in it's own way though, perhaps especially as it's hanging on where it is.
Five Wells (Park in Chelmorton and walk up)
Park Gate (Beeley Moor) Hob Hurst's House (Big Moor) Easy walk from Hell Bank plantation.
Eyam Moor is a magnificent location, to my shame I didn't manage to locate much but muddy boots up there a week or two ago on a brief jaunt, though, the heather is quite high. Not something to do on spec without research...? :D
...

Plenty of Hillforts. Fin Cop etc. Mam Tor of course.
Maybe a cave, Thor's Cave?
or as somebody said, Rowtor Rocks?
