I set up a private day tour of the Cu Chi Tunnels, including an airport pickup, with Mr. Giang. He was great at keeping me in the loop and the price was competitive. The guide was there when I arrived at the airport and spoke great English. He gave me a brief overview of HCMC and the role that the Cu Chi Tunnels played in the war while we were driving to the tunnels, which was very helpful in providing some localized context. The tour of the tunnels was very comprehensive and informative, so I left with a much greater understanding of this area during wartime.
