In reply to Oujmik: If it's winter North Lees is great but isn't too good once it warms up. It suffers from midges badly and short notice trips are difficult as you tend to have to book in advance once the weather gets better.
Hardhurst farm has possibly the best breakfast in the peak district, fried derbyshire oatcake anyone?
My favourite was Eric Byne as it tends to still be pretty quiet even in summer although no showers.
