The Mekong Delta in Vietnam offers a breathtaking backdrop, especially in the rainy season. It rained surprisingly little this October, possibly due to climate change. The rain showers are usually short and heavy and the temperatures are usually high. In recent years, various dams have been built to protect the people and the fields, which are supposed to make life easier for the people there. You can reach the region in about 6 hours by bus from Ho Chi Minh City, by the way, the buses are super comfortable with reclining seats and of course with free wifi.
