Great to see you made it to Woolfox Lodge Simon. I used to drive past the place on a daily basis until about 5 years ago, and on cold, bright mornings especially I could clearly see the watch office and always meant to go to explore.
In the end, due to the comments I have heard about the landowners not granting access, all I have ever managed to get are a few pictures from outside the fence.
