We booked a mouth tour as a trip of a lifetime with Indochina Treks which we have just managed to complete before the madness started. 24 days of hotels, boats, planes, trains, transfers, guided tours and cookery courses all organised to perfection by Kelvin Do and his team. He was infinitely patient with my many questions and super responsive - frankly he put the other tour operators I was considering booking with to shame, with the speed of his responses and knowledge. He was also very competitive on costings. This was the biggest ever trip of our lives and we felt in very safe and knowledgeable hands. We cant recommend Indochina Treks highly enough. I would definitely book with them again once we are able to travel again.
