I was in Vietnam four years ago and one of my favourite parts of the trip was NInh Binh. The scenery was just stunning, possibly even more amazing than Halong Bay. I am planning on returning to Vietnam next November with a new partner and would like to travel to a similar destination. Would Mai Chau be a good alternative? Where else would you recommend at that time of year that has similar scenery to Ninh Binh, Tam Coc etc?
