I checked Google maps aerial photo to remind myself of the site & just one review said their pitch had been flooded after heavy rain, but the staff found them another pitch. That could happen almost anywhere in poor weather.
Tewkesbury CAMC has delayed its opening due to flooding … appreciate that Winchcombe is on higher ground but the Cotswolds has had a battering from rain in the last few weeks so worth a chat with C&CC themselves to see what conditions are like.
