This is a complex history. We really appreciated the thoroughness and thoughtfulness of Michael's tour. There was a group of 30 and he was still able to navigate the questions and crosswalks without a problem. We appreciated the shady spots, places to sit along the way, bathroom break, and water stop. It is not a lot of walking but a lot of information! It is not touristy but more educational. His ability to share the difficult choices facing the government, mainlanders or HK residents was fascinating. He also took time to recommend tourist spots, peak times and restaurants. It was very much appreciated. The requested "donation" for the free tour was well worth it. I advise anyone coming to HK to take the time to do this tour!
