Hi.
There are several good ROCKFAX climbing guides which may be useful to you. They all cover several crags
in the Peak District park for a variety of grades. Each one is plenty for 3 days.
1) Western Grit
2) Eastern Grit
3) Peak Limestone
Ordnance Survey maps of the Dark and White Peak will be good for walking.
1) Camping at North Leys (below Stanage Edge)
2) Bunk houses (Check the BMC)
3) Millstone and Scotsman Pack pubs are excellent for food and drink, but not cheap to stay in.
Hope some of this helps. Have a great time.
