I’m aware of it, but there’s a few too many gates for my liking and if you use it you can’t impress people with your exhaust note through the tunnel.
They don’t like you using the term ‘cafe’, it’s signed as a ‘Tearooms’, cafe suggests you can obtain substantial food there. (Which you can’t, other than a tea cake or crumpet)
I remember one year turning up here on Boxing Day, the lady came out of the cottage and put the kettle on for me, top lass. I’ve also turned up on New Years Day to find a meeting of vintage British motorcycles.
The only picture I could find of the tunnel, I’m sure I have more.
