This 5-day trip was very rewarding. Our tour guide, Joe, was very knowledgeable, sharing a lot of geographical and historical information, and he also has a strong interest in stones. He also took care of our needs for regular bathroom breaks and three meals a day. Although there was a bus breakdown on the second day, his positive attitude and sense of responsibility were admirable. Although the itinerary was tight, I enjoyed it and took many beautiful photos. I'm grateful that the tour members were like a family, helping each other. Many of the hiking sections require a certain level of physical fitness, so it's recommended to choose a suitable route depending on your individual abilities, and it would be better to have hiking shoes.
