We caravan all year and always have done, We try to find sites with hard standings as grass is completely useless in winter and we do usually return to the same sites each year. we have a portch awning to use instead of the full one as its easier to dry if it rains and only ever use propane as butane tends to freeze in winter. this year we have a site booked every three weeks up to the week before christmas when we are away all week, we will come home christmas eve then go away on the friday before new year coming home again on jan 2nd, we then will use the van every three weeks throughout the year for weekends as well as five full weeks for anuall holidays. winter is a superb time to spend in the van all cosy and warm inside at night with the frost showing the true glory of the british country side in the morning. cant really comment on sites in the bath area as i live so far away but if your in the northwest try peak gateway in ashbourne or three rivers in clitheroe, these two are our favourites as they both have superb walking for the dogs in the countryside, also try holgates in silverdale, a truly superb site but very expensive and i think they shut for a few weeks each year. if you have not tried winter you are missing out on one of the best reasons for owning a caravan, holidays all year.
