From BB4: Continue along the track to the footpath marker, take the footpath to the left around the back of the farm. Go through the kissing gate.
The Barnacle Bimble is a circular walk of approximately 7 miles along well-marked and reasonably well-travelled footpaths, and the Coventry/Oxford Canal towpaths. No hills. There is one (dog-unfriendly) stile. Parts of the trail can get quite muddy. The route crosses a couple of busy roads where caution would be advisable.
