Thailand, Cambodia and Vietnam Tours for Young Adults
Imagine eating noodles from a street stall in Bangkok while scooters pass by, then a few days later cycling between the stone towers of Angkor Wat near Siem Reap. In Phnom Penh, afternoons drift between markets and riverside cafés, and on Koh Rong the day might just mean a long swim and a cold drink. Chambok Village moves slower, with forest walks and homestays. The trip keeps changing, which is part of the appeal.

Bobby made my trip to Vietnam stress free and unforgettable! He was very knowledgeable about Vietnams war and history which enriched the experience. I always felt safe and supported as Bobby took the time to constantly check on group members and made sure everyone got home safely on nights out. Bobby’s funny and lighthearted personality really uplifted the groups spirit. Thank you for the trip of a lifetime, Bobby!
