We saw a lot of the great buildings (Arts and Sciences are incredible) and heard a short history on the tour, but most of the group was Dutch speaking so there was a lot of just sitting around waiting for the explanation in English. And when we had had our explanation we were rushed into and out of the Cathedral which we could have seen when they were having the Dutch translation provided. The tour guides were helpful in answering our questions on good places to eat and drink around Valencia. There was also a lunch stop we didn't know about, so there was a lot less cycling than we were hoping for. All in all, I would say an average tour but if they made just an English one it would be good.
