For those who love the environment and culture, an easy day excursion from Hanoi to Ninh Binh is ideal. See the canals, karst rock formations, grottoes, and temples of the Ninh Binh area by taking a day excursion outside of the city. By riding past towns and through agricultural fields on a boat trip down the Ngo Dong River, you may learn about the history of the previous reigning dynasties.
