Such a experience with learning of saddened history that have tremendously impacted all human kinds. Ziggy was a great tour guide who has thoroughly explained every major parts in detail in a very professional manner. Highly recommended!
There’s no guide. You need to visit by yourselves. We just found that the tickets are free（after 4pm ticket) , so the whole tour was just included traffic, a little bit instructions and guidebook, also the book was shared by two people.
The driver is on time; and the tour guide is professional,he is patient to answer the questions that we asked, I really enjoyed this trip.(Of course,the history is really sad but you should know it)
Our guide, Chris, is absolutely amazing! He speaks English well and very knowledgeable. He is so nice and drives really safely. I believe that our group is surely satisfied and lucky to have him.
