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.

What people love about Thailand, Cambodia and Vietnam Tours for Young Adults
- Ultimate South East Asia
The main reason I booked a tour was because I had no time or desire to plan a full itinerary for the places I wanted to go. Moreover, while on the trip I wanted to do as little work as possible to see and do as many things as possible! I can say with absolute certainty that this tour, especially with Jules as the trip manager, far exceeded my expectations! There was not a day that I wasn’t seeing amazing new sights or going on some kind of adventure. Aside from the trip itself, I felt like myself and the rest of the group were in great hands with Jules leading us through Asia. She was very thorough with briefing us with what to expect for the days ahead that nothing ever caught me by surprise! Even when unexpected things did happen, I am very happy that Jules was there to resolve any issue that came our way. I would 100% recommend this tour with Jules as the trip manager!
- Cambodia: Ancient Ruins & Boat Rides
Amazing destinations with very enthusiastic and friendly guide. Accommodations in the latter half were not the most luxurious, but that didn't really detract from an amazing experience overall.
- Amazing Vietnam & Cambodia & Thailand ends Bangkok (4 Star Hotels)
The pros: fantastic guides in Cambodia & Thailand! It was evident that Kea & Chino loved their countries & really knew their history. Both were very personable & knowledgeable and enjoyed engaging with the group while introducing us to their home. Sites in both countries were stunning & well worth visiting. There were a couple of long days on the bus, but they were broken up nicely with interesting stops. Both had excellent suggestions on what to do & how to get there during free time. While there wasn't a lot of free time built into the tour, most people went out & about even if it was just for dinner after reaching the hotels (which were all FANTASTIC). Sites were thoroughly explained, giving us a deeper appreciation for what we were seeing. Cons: Vietnam. Our guide blew off our arrival meeting....he was stuck in traffic with an existing tour (that we were added on to). We sat for about an hour waiting for him until WE finally had to get ahold of him to find out what was going on (he knew he was running late, he knew we were waiting in the lobby & he couldn't be bothered to call the hotel & let us know he was running late?) He was suprised that we called, said that the evenings planned events on our itinerary were "no big deal" and canceled them, telling us to meet in the morning. Upon meeting in the morning, he offered no apology for missing the nights activities. The Sites we saw in Vietnam (bird sanctuary/ gator farm) were ok.....likely the only thing to do between Saigon & the boat to Cambodia....but not anything to write home about, certainly not up to the standard of the rest of the trip. More like places elementary school kids would go on a field trip. Mr Phat (the guide) was having to use Google to answer the groups questions. In conclusion, Vietnam was kind of 3 wasted days on this tour. (Although the group we joined had done N. Vietnam & it looked great). Once in Cambodia, it really took off. They are warm, wonderful people who do everything they can to make your visit the best ever. They're clear eyed about thir history, the good & the bad, and want to share it all. Thailand was lush & beautiful. The temples & palaces had that "wow" factor. This is a fast paced tour, but I never felt rushed. I'd definitely go again. Though I'd lose the 3 days in Vietnam or add on extra days in the north.
