All three locations are quite far apart, so a day trip was much more convenient. This time, the group was smaller, so we took a small bus. Our guide was very attentive, explaining the history and characteristics of each attraction. Although it rained during the trip, it didn't diminish the beautiful scenery, making it a truly worthwhile experience.
