The 27-day trip was very exciting, adventurous and you could make new acquaintances. You became part of a family during the trip. Grade 10. Our CEO Kosal was like a family man to us and looked after us well on the whole journey from Hanoi to Bangkok, grade 10. The journey on the three night trains was an adventure, not for me as the hygiene standards are not as high as in Western Europe, grade 5. Travelling by bus from place to place was great, we often had the same bus driver, they were very helpful, grade 8. The accommodation (double rooms booked to share) was OK and mediocre, the double rooms were better than the multi-bed rooms, but were only mediocre, especially in big cities, grade 6. The included excursions were top notch and also showed the regional life of the population, I especially loved the G-moments (NGOs supported by G-Adventures) grade 9. Optional excursions, sometimes too expensive for what they were, especially North Vietnam, grade 7. When booking on the G-Advetuers platform, It was tedious, they had a glitch with the booking platform, and it cost me a lot of nerves and patience until everything was back to normal. All in all, I was very satisfied.

Laos & Cambodia Family Adventure - December 2025

No booking fees

Best price guaranteed

Take your family on a superb adventure to discover the ancient history and cultural landscape of Laos and Cambodia. A carefully crafted blend of family adventure activity, comfortable child friendly accommodation with select moments for downtime to simply enjoy your surroundings, this is truly family travel at its finest. Our adventure begins in the magical town of Luang Prabang, Northern Laos, where you and your family step back in time to a place where every morning hundreds of saffron-clad monks file out from the monasteries to collect alms from the devout residents. You’ll explore the local markets and ancient temples of this former royal capital, take a boat trip on the mighty Mekong River to the mystical Pak Ou Caves and hike though lush forests, around rice paddies to marvel at the turquoise pools of Khuang Si Waterfall. Overnight at the The Elephant Conservation Center, a 530 hectare natural elephant habitat home to 29 Asian elephants. The centre, unlike most elephant camps, was set up purely for the protection of this magnificent species and aims to return elephants to the wild. This is truly an experience not to be missed. Then fly south to Pakse - explore the ancient Angkorian ruins of Wat Phu before continuing on to the 4,000 Islands and the largest island, Don Khong. Immerse yourselves in the relaxed lifestyle of this sleepy riverine archipelago. Next, fly to the lively town of Siem Reap, Cambodia, the gateway to Angkor Wat. Explore the ancient passageways of Angkor Wat temple, marvel at the enigmatic giant stone faces of Bayon, uncover mysterious ruins deep in the jungle on Kulen Mountain, kayak through floating villages and be enthralled by the energetic performers at Phare, the Cambodian Circus.

Ho Chi Minh to Angkor Wat Cycle - December 2025

Did this trip with my 20 year old son. Great father son bonding time experience. Would go back and do it again happily. You need to be pretty fit to get through the whole event. Definitely take factor 50 sun cream, gloves to keep your hands from burning, long sleeved tops and loose trousers to cycle in. It was 35 to 37 degrees when we went in early February. Guides were amazing, off road bicycles were great. The last two days in Cambodia were pretty arduous but the day cycling around Angkor Wat was an all time highlight of my life.
