We had a fantastic time! All the hotels were excellent, the tours were well-organized, and the guides were incredibly helpful and knowledgeable. I was traveling with my daughter, and as we're not very experienced travelers, it meant a lot that we always felt safe, supported, and well taken care of throughout the trip.

The tour was an incredible experience from start to finish. It was well-organized, informative, and filled with beautiful sights that were truly unforgettable. The itinerary struck the perfect balance between adventure and relaxation, making it enjoyable for everyone in the group. A big part of what made the tour so special was Lachlan. He was not only professional and knowledgeable but also kind and approachable. He went above and beyond to ensure everyone felt comfortable and engaged throughout the journey. Highly recommended!

This tour was such a great way to explore both Vietnam and Cambodia without stressing over planning everything ourselves. It started in Saigon... super lively and full of energy. The Cu Chi Tunnels were very intriguing.. it’s wild to imagine how people lived down there. One of my favorite parts was the boat ride on the Mekong River.. saw floating marktes. Hoi An was hands down the most charming place on the trip with lanterns everywhere, cute cafes and lovely shopping.. I bought silk scarves and handmade lanterns. Hanoi had a completely different vibe, like more historic and chilled. We spent a day just walking around the lakes and old town. Ha Long Bay was unforgettable.. saw limestone cliffs, wow! The Cambodia part was shorter but still amazing. Angkor Wat and Angkor Thom were mind-blowing.. Overall this tour was well and everything from the hotels to the food and transport was taken care of. It’s a lot to fit in but if you’re looking for an adventure across two beautiful countries.
