One of the best experiences Ninh Binh has to offer! The tour runs from 9am to 5pm, and includes multiple hikes around beautiful locations, beautiful landmarks such as the prehistoric cave, entry into the conservation site, and a scenic river boat ride. The national park was beautiful to visit and there were so many butterflies in all locations that we hiked. The prehistoric cave was daring, scary, but very beautiful. We had the opportunity to go inside and explore and even go up to the 2nd level of the cave. We enjoyed a lovely lunch and hiked to a gorgeous reserve with a scenic pool and lots of butterflies. On the way we saw lots of wildlife, critters and flora which were spectacular. Our guide, Binh, was very energetic and kind. He was very informative and pointed out lots of critters while we hiked. He is very experienced and a great guide. Would definitely recommend booking this tour as it was an inclusive and amazing experience, with a great service.
