Hi jo anne
Hurn Lane is good site, next door to large commercial site, to walk dog you can leave the site on foot, go down the quiet lane, and you will come to common, so lots of space, as also said beach is good for dog walking too, recommend 'The Place' along the road for food.
Cheddar site is not typical CC site, although it is improving, when we were last there the planned improvements were held up by an archaeological survey,site is next door to football club, dog walking is best along the lane outside the site, virtually traffic free, and goes alongside small stream.Large car boot/ market just up the road and a large garden centre with restaurant as well.
