If karst scenery of Ha Long Bay is not enough for you, check **Ninh Binh**. Explore the countryside around Tam Coc village dotted with green humps of limestone hills. For Ninh Binh, take a train to Hanoi and then change for [Hanoi–Ninh Binh](/en/travel/hanoi/ninh-binh) train. It may seem illogical, but this combo train+train travel will most probably take you less time than a direct local bus from Haiphong to Ninh Binh.
