This was a great tour however, started off a little sketchy. We started off with an English speaking tour guide in a tour van and once we reached the Thailand border, the tour guide switched and we were transferred into a small vehicle. The second tour guide was very nice however, spoke minimal English. I would not have minded however, the tour was advertised with an English speaking guide. Amazing sites. I wish I could have known a little of the history or tidbits of what we were seeing.
