Trang An.

On the route of the new waterway, visitors will begin their boat journey by embarking at Trang An wharf before being ferried to destinations such as Trinh Temple, May cave, Tien stream, Dia Linh cave, Dai cave, Hanh Cung Vu Lam and the filming location for ""Kong: Skull Island". The duration of the journey is about 3-4 hours.
Trang An eco-tourism site is part of the Trang An Scenic Landscape complex and located in Ninh Binh province, covering an area of 2,200 hectares. About 90km away from Hanoi, the complex was recognized by UNESCO as a World Heritage Site. According to the plan for development, Trang An eco-tourism site will ultimately have nine tourism waterways and two road routes. The opening of the latest route will help increase the number of waterways for tourism in Trang An to three. 
At the launch ceremony, visitors were treated to a show of the cultural and historic spaces of the Dinh dynasty and were able to row a boat along Sao Khe River. Apart from visiting beautiful landscapes of Trang An complex, tourists had the chance to enjoy some royal music of the Nguyen dynasty as performed by local artists.
The third waterway at Trang An eco-tourism site will officially open for business on the first day of the Lunar New year with tickets priced at VND200,000 (US$8) each, according to schedule.
U.S. travel site Insider has named Vietnam’s northern province of Ninh Binh as one of the 50 best spots to visit in 2018. The honour reflects the province’s mesmerising mix of rivers, limestone cliffs and paddy fields. Ninh Binh was one of the three locations for the movie "Kong: Skull Island", one of the biggest Hollywood blockbusters of 2017.
