Went on a Mekong River tour from Ho Chi Minh (former Saigon), which I unfortunately can’t recommend it’s way too commercialized, I did go from on stop/shop to the next and didn’t see or get the vibe of the Mekong River and the people living there. If you go there I would recommend to go there on your own and not with a tour to really get an understanding of the area and the people.
This obviously didn’t stop me from taking some beautiful pictures, which (hopefully) don’t have a ”touristy vibe”.
