Well I went there and didn't find a link to Tolkien trails so I did their Site Search for "Tolkien trail" and found "3 Trails". I click on that link and think their "Fellowship Of The Ring/J.R.R. Tolkien Trail" is the one Mellon meant.
When I tried to make a link of that page it came back with an error probably because it was the result of a search. So those interested will have to follow my above path. Starting with this link: 24hourmuseum
