If you are looking for a cheap option and you are not picky, then you might want to consider this tour. The operation company 'West Coast Holiday tour' is not the best, their employees are not friendly but they provide basic services.
It was an amazing day with short and quick visits to two wineries and Castello Castle is an outstanding construction. Nature at it's best and pleasant to eyes. Except the short time at each wineries everything else went well and as per itenary mentioned. Thanks to tour guide, who was kind and friendly.
