It was an interesting experience. Our tour guide was knowledgeable but was not too welcoming. You will basically see 3 medieval villages. Each one with a different story and architecture. We went in January and because it was winter, most of the shops (in one place all of the shops) were closed.
This was a fun tour! My husband and I LOVED our tour guide. She was very good and knowledgeable not just of the winery but of barcelona city itself so the tour started the moment we entered the car. Very interesting how they make the wine (cool machine!) and really good wine too. Nice castle also.
