Can Tho is located in the Mekong delta in south Vietnam. I came there by bus and had a very nice time in the city being shown around by my Couchsurfer, Ngoc. Sadly I had to stay at a guest house due to rules which forbid girls to host male guests.
We did a Mekong river boat trip with a visit to a local rice noodle factory. They grind rice, cook it and form rice paper. This rice paper is dried outside in the sun and then cut into rice noodles.
