Traveling for 16 days across 4 countries with my best friend was our dream since high school. Each activity planned was fantastic, and the experiences in every country were unforgettable. Dat made us feel at home throughout the journey, and we particularly appreciated local guide's support during the trip. Thank you for an amazing experience—I'll be recommending this to everyone!

Ho Chi Minh to Angkor Wat Cycle - May 2026

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.
