Did a 4 day, 3 nights trip from Nha Trang to Mui Ne with Tony and James, May 2013. As older backpackers aged 53 and 66 ,it was highlight of our trip. The boys met us the night before the trip to show us their bikes and explain where we would be going. The best day was on day 2 when we went to the market to buy food to take to the Nat park , set a fire and cooked the best food ever (talking to other people with other Easy riders, they went to Nat park but did't do a BBQ). Also stayed in a long house with was great (something other easy riders dont do).It was my birthday on the trip and the boys presented me with a birthday cake and as they said when they first met us , we would start off as clients but will end up as friends.
So if you are looking to do something different and see the real vietnam, eat the food the locals do and stay in clean places and travel the way the locals do then this is the trip for you.
PS ask to have Tony and James as your guides and just email RIVER !!!!!
