Our guide Borin - never boring!
Our guide Borin, in Cambodia, was knowledgeable, understanding and thoughtful in every aspect of the plan he put together for our trip to Siem Reap and in its execution. He can read the room, and knew exactly how to pace the tour, when to pause, when to break, and how to prepare us for the maximum benefit. He is extremely kind and caring, and it showed at every turn. He also is a dab hand with the camera, and we have a lot of great pictures to show for it. Kudos to my Asia Highlights coordinator - Cathy Chen, for picking Borin. Borin works with a driver (007) who was also very kind and caring. Whenever we returned to the car, he would have cold towel rolls and chilled water to refresh us. So amazingly considerate. It was an unforgettable experienceMore

We've had such a great experience…
We've had such a great experience planning our honeymoon with Alisa at Asia Highlights! We gave her our dream itinerary, thinking that it might be impossible to do all the things we wanted, but Alisa made our dreams a reality! She's gone so far above and beyond to answer ALL of our questions and make little adjustments that will make a huge impact on our experience.More

In addition, I want to specifically mention the guides provided in certain locations. Rum, in Siem Reap, made the most memorable experience possible. His positivity was contagious - even when it felt like 1000 degrees and we were tired. He brought it all to life, and created a couple days of Ankor Wat, etc. that we will never forget! He heard my daughter's request for specific Cambodian food, and changed our itinerary to go to a village and eat at a locally known shop. He brought the dessert she asked about to us in the car! Overall, he and his driver "Lucky" were a reason to go to Siem Reap. In addition, the other guides (minus one which was switched out immediately) were stupendous. Mon in Bangkok was friendly and provided a great day there; Eak in Chiang Mai gave us a world-class food-tour and day touring the city and its surrounding temples with lots of laughs; Tommy in Hanoi kept us from getting killed in the traffic and gave a stupendous food and architecture/history tour - so very friendly and funny; the fishing village tour in Hoi An, as well as the side-car tour in Saigon, were both unforgettable! Thank you Sharon, and Asia Highlights. Would definitely use again for future trips!More

My daughter and I wanted to discover SE…
My daughter and I wanted to discover SE Asia. Being the first in that region, we wanted to use a tour service company. We ended up using Asia Highlights. From the beginning we were impressed with their services. We left home with of mind because all the pre-travel arrangements were taking care and communicate to us efficiently. All our questions were answered promptly. Once in the countries, we were welcome by our excellent tour guides. Everything was taking care for us. We did not have one issue. They selected the right tours guides for us, they were highly knowledgeable and so much attentive to our needs. We had Dhat in Vietnam and Borin in Siem Reap, Cambodia. I highly recommend Asia Highlights. I came back home so much rested, and with plenty of wonderful pictures and memories. I will definitely use Asia Highlights again for my next trip to Asia.More

Fabulous tour and guide in Cambodia
We have been touring Cambodia, guided by Borin ( and driver 007) for the last 2 days. What a fabulous experience! Borin has been a wonderful guide, the best so far in Southeast Asia, explaining the history and culture of Cambodia through his tours of the temples in and around Angkor, as well as the Landmine museum. He has answered all our questions, made sure we were comfortable, and that we have had great food. 007 made sure we always had enough water and cool towels for our face/neck.We highly recommend Borin as a tour guide for Cambodia!!More

Best Travel Service for Asia Travel
Alisa Liu was in charge of making the arrangements and she helped us from the start to make all of the arrangements and also helped us when we had questions and requested some adjustments. Her service is of the highest professional level. We are 100% confident that our trip will be perfect. We’re also 100% confident that, if anything comes up during our trip, that Alisa will be there to guide us through and take care of us. We won’t even consider using another agency for travel around Asia and we would like to have Alisa work for us again.More

Tour of Vietnam, Cambodia, Laos and Thailand
The tour guides and drivers were another high point. All were very good, friendly, knowledgeable and spoke English well. There were two that I want to call out for their excellence. Chan Sovannarith in Siem Reap was our guide in Cambodia. He really made the experience special. His knowledge, willingness to answer all my questions, helpfulness and general attitude made him fun to be around. In order to praise the second exceptional guide I have to explain about an unfortunate occurrence that I had. I'm normally a very active senior, but after leaving Cambodia for Laos I was suddenly struck by the most intense back pain I've ever experienced, couldn't even roll over in bed (turned out to be sciatica). The guide, Mr. Sonophet, really went the extra mile. He went with my traveling companion and bought a back brace and medications for me. When that didn't help much he took me to a clinic where I was seen by a doctor, given a shot and pain meds. He hand-made a walking stick for me that I'm still using! He made it possible for me to somewhat participate in the activities, i.e. a bed on the boat down the river. When it was time to move on to Bangkok he got me a wheelchair at the airport. I can't thank him enough for these kindnesses! This problem lasted for the remainder of the trip, through Bangkok and Phuket and these guides were also very helpful getting wheelchairs, etc. It was a terrible disappointment to have this wonderful trip disrupted, but it would have been SO much worse without the great help that I received from the guides and my poor travel companion!More

In good hands with Sam
Sam Ol took very good care of us - lots of information, listened to and answered all our questions, was passionate about the places we visited and about his people and country. He was kind, had a great sense of humor, and made sure we felt safe and comfortable at all times. He helped us to fall in love with Cambodia in 3 short days.More

Best tour guide in Cambodia
When we first arrived at the airport in Siem Riep it was so nice to be greeted by Mr Sam Ol. We instantly fell at home when we saw his friendly smile. We were impressed by his great English and knowledge of the temples. On the tour to the temples Sam took care of us every step of the way. He took awesome pictures of us. It felt like we were on a tour given by our brother who is also a professional photographer. Also, we appreciate his humor as well as the fact he had an answer for every question we had. I give Sam 5 stars, best tour guide ever :)More

The Best Places to Visit in Cambodia in September
September is a great month to travel to Cambodia if you are keen to avoid crowds and happy to take a chance with the rain, which often falls in the afternoon and night. Here are some of the recommended places to visit in September.
1. Angkor Wat
No matter when, Angkor Wat is a must-see destination for most guests traveling to Cambodia. The crowds are sparser in September, making it the best time for a relaxed tour. You can expect to see photogenic temples reflected in pools of water, glistening stone structures, and deep green vegetation. Take a moment to breathe in the fresh, rain-washed air in September.
2. Mahendraparvata for the Phnom Kulen Waterfalls
September is a good time to see the waterfalls of Cambodia. Cambodia is home to several breathtaking waterfalls, which are a delight to visit, especially during this rainy time of the year. Do consider venturing out to the Phnom Kulen Falls in the ancient city area of Mahendraparvata. This recently rediscovered city is symbolic to Cambodians, as it is believed that this was where the Khmer Empire began. Other waterfalls you can stop by include Teuk Chhou Waterfalls in Kampot and the famous Boo Sra Waterfall in Mondulkiri Province.
3. Tongle Sap Lake
September is a good time to visit Tonle Sap Lake (biggest lake in Cambodia) as the frequent and fierce rainfall makes the lake bigger and at its most vibrant. Many birdwatchers come to take photos at this time. Take a boat tour to visit the flooded forests and floating villages around Lake Tonle Sap and relax yourself by breathing the clean and fresh air after the downpours.
4. Kratie: Natural Beauty and Wildlife
The tropical province of Kratie turns completely green in September, like the rest of the dense northern jungle of Cambodia. The area encompassing Kratie boasts a variety of flora and fauna, especially in the huge nature reserves, where monkeys, different species of reptiles, and rare river dolphins can be spotted. Spend some time to visit the Mekong Turtle Conservation Center and Phnom Sambok Pagoda if you have more time.
5. Phnom Penh
The capital Phnom Penh should be on your list for a trip in September. There is so much waiting for you to explore in the capital of modern Cambodia and the ancient Khmer kingdom. There you can explore the Royal Palace complex to appreciate the beauty of the architecture and learn more about the history of Cambodia. Spend some time at the Killing Fields of Choeung Ek and Tuol Sleng Museum (notorious prison S-21) to feel the historical terror the nation suffered under Khmer Rouge rule. Read more on the top 8 things to do in Phnom Penh.
Crowding and Costs in September
September is in the low tourist season because of constant rainfall, which makes it challenging to visit different destinations. For this reason, fewer tourists visit Cambodia this month, and most hotels offer good accommodation deals and bargains. All of Cambodia turns lush green, and the lakes expand in size due to the countrywide rise in water levels.
Clothes to Wear in September
Although September falls in the wet season, it is important to note that Cambodia is a hot and tropical country. Synthetic clothes have the benefit of being more quick-drying and breathable, but choose natural fabrics such as silk, cotton, and linen to keep you cool and comfortable when not so active. Loose-fitting light clothes such as long-sleeved shirts and trousers will help protect you from mosquito bites. As it tends to get warm or hot during the day and stay warm in the evenings, jeans would not be a good choice. As there is much rain during September, remember to pack a raincoat or poncho and a light pair of walking boots or shoes, depending on the activities you plan on engaging in.
