Best experiences! I decided book Ninh Binh tour 2 days. It was funny, our guide Ms Linh was very knowledgeable and well-organized. The scenery of Ninh Binh was very nice, fabulous. I loved local food, ride bicycle around countryside, cave explore in Trang An with boat trip was fantastic, trekking Mua Cave. 2 days not enough to discover this city and we will back to see more places not yet visit. Thank you so much for having a well-arranged trip for us
