We had a fantastic trip. Bamba gave us all the information we needed and the guides during the tours were great. We loved Vietnamese countryside, the floating market and the tour to the Cu Chi tunnels was very interesting. Highly recommended, you won't be disappointed.

There is no better way to see a country than to ride it. This average daily distance is ideal for anyone. Even the most unfit one in our group who struggled a little, (just a little), on day one, coped admirably overall. Book it, you will not be disappointed.

This trip was a real eye opener into a very different way of life. It was very educational. We enjoyed the perspective of the local people when it came to past issues i.e, the war in Vietnam, the genocide in Cambodia. The group size was wonderful and we got to know each other very well.

From the Mekong Delta to Siem Reap (port-to-port cruise) - September 2026

No booking fees

Best price guaranteed

From the heights of the Himalayas to the southern coasts of the South China Sea, winding over 2,700 miles, the Mekong is much more than just irrigation for Indochina—everywhere it flows, it fascinates men and shapes their lives. Come take an expedition on this grand and plentiful “water snake,” from Ho Chi Minh City, still largely influenced by the French colonial days, to Phnom Penh, then Tonle river, following the footsteps of Henri Mouhot. Our meditative trip takes you along the Mekong River on board a ship combining charm and colonial-style comfort.

Discovering a trustworthy, knowledgeable, and caring tour company can be challenging, especially when time is limited. Luckily, my husband and I were incredibly fortunate to find this amazing tour company. With her assistance, we planned our itinerary, expedited our visa, made last-minute changes, and still experienced the wonders of northern Vietnam in a safe, memorable, and truly wonderful way. The team was exceptional in handling all the details with flexibility, patience, positivity, and proactive care. Their professionalism and kind-hearted nature made a significant difference in our journey. A big thank you to out tour expert and her associate for their outstanding care and ensuring an awesome and amazing Vietnam adventure! I highly recommend this tour company for all your Vietnam tours.

We have just come back from 2 incredible weeks in Vietnam and Cambodia, all arranged by the travel company. We had an incredibly memorable holiday and can’t thank Chloe enough for arranging such an interesting trip and also organising everything so perfectly. Our guides were all fantastic. We learnt so much more about how incredible Vietnam is thanks to all the information and personal experiences they shared. Our travel expert booked us into some lovely hotels and all of our transport arrangements worked perfectly. Highly recommended
