This trip is a fantastic opportunity to learn more about the history, cuisine and the way of life in the capital cities of Ho Chi Minh, Phnom Penh and Bangkok. The itinerary also allows you to see how people live, work and socialise in rural areas which is what makes this trip so fascinating. During my 14 day visit I was able to learn more about the Vietnam war, the way of life in the Mekong Delta, the actions of the Khmer Rouge (the toughest part of the trip in my opinion) and the history of Angkor Wat & Angkor Thom. The itinerary also allowed our group some relaxing downtime which involved sunbathing, snorkelling and fishing off Bamboo Island (near to the resort of Sihanoukville, Cambodia). This trip does involve 2 fairly long trips by bus to Phnom Penh and Siem Reap although we were given a number of comfort breaks which included a stop at Skuon and a chance to hold a live tarantula and sample a fried spider!!

I felt the G Adventures tour provided experiences you could not get on your own, and made the travel stress-free. You spend the time enjoying the experiences and not having to think about logistics. The local guides and CEO were all fantastic cultural translators who went the extra mile to provide a rich experience.

My wife and I truly enjoyed this incredible tour. The 3-star hotels exceeded our expectations, not only in comfort, but also in location, allowing us to easily explore local life. Every pickup was seamless. The tours themselves were well-organized and each experience was memorable. Honestly, our only regret is not having more time in each of these amazing places! A special thanks to our dedicated rep, Evelyn, who supported us throughout the trip. This was a 5/5 experience, and we’ll absolutely be recommending it to family, friends, and colleagues!

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.
