Highly recommend going to Ninh Binh! Started the tour by hiking up to Ngoa Long Mountain. Its all stairs round trip was about 45mins so not too bad. But you get a really nice view of the area from top.
After we got down we biked around the area and made pit stops along the way.
After the bike we went to lunch at a local spot that the guide took us to which was really good.
Then 1 hr long pagoda ride along the river. Really nice views.
Last stop was at a template nearby.
Overall the trip was the whole day from 7am to 6pm-ish
