Surprisingly surprise. I took a Vietnam tour with this company before, and this time I chose an itinerary starting from Thailand. I have to say the quality remains just as excellent! We were concerned that my husband wouldn't have enough activity, but that wasn't the case at all. We were able to visit local villages, and go for walks or short hikes daily. It was wonderful.

I truly enjoyed the 2 weeks that I spent in Malaysia, on Borneo at the beginning and on the Malay peninsula at the end. Accommodation was of a high quality with the possible exception being the long house for 1 night in Borneo. There were separate guides in the 2 halves of Malaysia, and both were simply excellent: Aldrin in Borneo and Ant on the peninsula. The trip was mostly at a leisurely pace which is what I like, and there was an ample amount of free time on some days, and that includes 1 total free day at the end on the island of Langkawi. This trip is a new one, and I think it's excellent. I highly recommend it.

I haven't quite absorbed all of what I have experienced on this trip. The animals, birds, insects and vegetation we saw is almost overwhelming. I have gained a stronger appreciation for this world we live in because of this trip. I will definitely take another National Geographic G Adventures tour in the future.

Beautiful and well-planned holiday with activities that both parents and children enjoyed. The tour guide was excellent with the children; he went above and above to give us detailed information about his home country, his family, what it's like to grow up there. We felt so welcomed there.
