Best route

Details, directions and map on Chew Valley’s own website. 

From memory (always risky!) you’ll need to approach via the A368 and you can do that from the west via the M5/A38 avoiding the worst of Bristol traffic or from the east via A4/A37 which will involve more traffic. There is a narrow section in Blagdon from the west, but can’t recall any obstacles from the east side.  

Thanks for the info. I wasn't sure whether to come around Bristol from Avonmouth or travel further along the M4 and come off at Junct 19 and skirt around that way. Sounds like traffic either way.

Thanks again.
