The Okanagan Valley has the most wineries per capita of anywhere else in British Columbia, so with that in mind, that region will be the focus. As with any of the links or suggestions Happy Holidays Motorhome Rentals provides, we advise you to do your own research to determine whether or not it is suitable to your needs and personal taste.
As you can see from the maps (provided by hellobc.com and found here), most of the wineries are clustered. If you stay at an RV camping spot within each area, many of these will be fairly accessible without having to travel great distances.
