The Trang An route through Ninh Binh is less busy than the Tam Coc waterway, with fewer tourists and vendors. Even though there are fewer visitors here, you should still arrive early if you want to appreciate this serene waterway. The route is 9.5 miles (15 km) total. Your guide is an experienced rower, and your adventure takes place in a boat that can typically seat around 4 to 6 passengers.

Trang An is often compared to Halong Bay because of its limestone formations and dramatic scenery. As you paddle down the river, you’ll pass through the tunnel caves. You’ll also see a cave decorated with ceramic jars, where locals used to keep their fermenting batches of rice wine. There are three temples along the way — tours typically stop so visitors can get a closer look.
