Does anyone know if Cycling is allowed on it and if its suitable for narrow tyre roads bikes?
Is that the 'Strawberry Line'? Strawberry Line permits cycling, but the path is not tarmac. http://www.thestrawberryline.co.uk/index.php?doc=147&rev=147http://www.n-somerset.gov.uk/NR/rdonlyres/EA892C65-C881-4A81-91FD-25FD30171670/0/document_200811_TheStrawberryLine.pdfI rode the Strawberry Line from Cheddar to Yatton during the summer* and the surface was mostly packed dirt or that thin sustransy gravel stuff. I imagine it can get muddy at times in the narrow parts. Someone's pics from August give an idea of the range of surfaces: http://www.flickr.com/photos/7493003@N03/sets/72157627502374092/with/6073580301/ * on 700x28s not really skinny tyres.Plenty of decent country lanes round that area, so you shouldn't be stuck for routes if the path is impractical. [ETA: nearby place is Congresbury btw...though Conglesbury sounds better! ]
You need lights for the Winscombe railway tunnel.
