If you are into architecture/steam engines google Papplewick Pumping Station its about 10 miles away down the A614 towards Nottm and is a wonderfully preserved victorian pumping station,I think its open at weekends.
The Major Oak is on your doorstep at Edwinstowe, Rufford abbey is just down the road as is Clumber Park,Thorsby Hall and courtyard is well worth a look again just down the road
