When doing the Ninh Binh boat tour you will consider Tam Coc or Trang An. Trang An is the best option now because of its beautiful scenery. You can opt for one of three boat trip routes available in Trang An Ecological Park below:
The 1st route will take you around 3.5 hours to visit a large number of limestone caves, nine in total. (If you are into cave experiences and feel comfortable with long hours in the rowboat, this route may be a good choice for you)
The 2nd route takes shorter time and fewer destinations than the 1st route. But the highlight is the chance to immerse in a real-life ancient world while visiting the “Kong: Skull Island” film set site. ( If you are a King Kong fan, Route 2 is a good option for you ) *Lam Cave - Vang Cave - Thanh Truot Cave - Dai Cave*
The last option will be for a relaxing purpose. Route 3 has the least of the destination and shortest time to spend. So you will have quick information about Trang An. (This may be the best Route for your photographers, you have more time to take photos, sightseeing.) *Dot Cave (also known as May Cave) - Van Cave - Dai Cave*
