“Loved every minute of this amazing tour!!! Max, OneWay and scotty have been great in every way to explaining everything in great detail and keeping the group up to date daily with what is going on. OneWay and scotty were great, friendly and very good at keeping a large group together and involved, also good at answering any concerns we had. I’ve had such a lovely time with them and don’t want this tour to end it’s been amazing!!! Loved it, will Definitely be booking another tour with trutravel :)”

“Boom and Gun have been excellent tour guides for the beaches part of our tour and I would recommend them to anyone. They both speak very fluent English and are always asking if there is anything they can do to help. They’re also very fun and like to get involved with the group which is great. They both made our time an unforgettable experience and proved it was worth every penny. I can’t thank them enough! Ali was also a good tour guide for the northern area of Thailand. He speaks English well and is always wants to help and ensure you’re happy at all times. He involved the group in making decisions which was nice as we got to choose our own times and things we done. Grace was also helping Ali on the tour and she was great too. Always helpful and very friendly. I would recommend both for future trips.”

“Papsii is a really nice & enthusiastic guide who has a good energy that gets everyone in a good mood. I decided to join the tour to south when I was doing the tour in the north, but everything so they had to arrange a lot at the last minute. They did a great job at that. Tip was really nice and made sure that everyone was happy. Gracie (intern) tried to really make an effort to know everyone and made sure that everyone felt alright.”
