If you are not interested in big crowds, green season (from 1st May to 30 Sep) is a good time to travel to Vietnam & Southeast Asia. It is the summer time and considered as rainy season but the heat is bearable, from 32 – 38 degrees and cooled off now and then with downpour rain. Travelling during this period offers many advantages. First is the low cost as there are promotions from all the hotels and with high availability. Secondly, you will likely have our best tour guides to accompany with, while they are often fully occupied in high season. Contact us for more great deals!
