Just posted a review of the Forest Hill Society walk around the Nature Reserve.
You can read the full details here.
You can see the photos here.
Technically these paths don't qualify as part of my quest, but the point of the walking is to explore the area and find interesting spots I might otherwise miss. This definitely qualifies.
I have joined as a Friend of the Devonshire Road Nature Reserve (FOTDRNS!) and volunteered to help, so I hope to go back soon. It might even give me a chance to access the equivalent reserve on the other side of the tracks (Gartmore Road Nature Reserve) that is otherwise locked for safety.
See you there?
