You will have to cross the M1 bridge so take this into consideration if your dog is nervous or noise sensitive. There are also fields with horses, they largely ignore everyone but you might find a delightful pile of poop here and there en route. 

There aren't many bins around and at the entrance to the lane, I have seen some flytipping / dumping which is disappointing but the woods itself tend to be pristine. You can google the trail or wing it when you go. The woods is generally a circular trail but with paths leading off. There is also a field which the trail goes through. It doesn't have the best drainage so if it has been raining, you can get a bit boggy. 

If you go during the spring, take your camera. Plenty of places for posing pics. And the bluebells are breathtaking.
