Hey up,
The 3 circles on Barbrook are well worth checking out......not a great deal of walking needed to get to see 'em....then again over the Barbrook brook itself is the Hut Circle and settlement/enclosure at Swine Sty.
The 3 circles on Eyam Moor are also worth it....but can be a bit of a pain to find...
Then there's the Hordron Circle and Bamford South.......these 2 are a bit more spread out than either the Barbrook or Eyam Moor sites.....but you'd be hard pushed to find better....
nice one
