What in your opinion, is the best time of day in Vietnam? I prefer the morning, because waking up in Vietnam is such a wonderful feeling. But also mid day and night time is quite nice as well. :) What time of day do you prefer?
night time when the weather is a little cooler.
If you're staying in HCMC, for me it has 2 of the best times of day. First one in the soon morning, and second one is the night time (after 8pm). In the morning (6-7am) you can enjoy a cup of coffee on some street coffee shops as local people there. And at night, you can know what is "nightlife city" through the hustle and bustle
