The area surrounding Tam Cốc is said to be one of the most beautiful places in the country. Here, large rock formations arise from the green fields, a sight which has earned the place the nickname "Ha Long of the Rice Paddies." The name Tam Cốc actually refers to the caves on the banks of the Ngo Dong river. The best plan is to take a leisurely float down the urbanized part of the river near the town and then explore the caves.
The boats hold two travelers and two paddlers who are in the back (they're usually old women). Sometimes, they conduct the boat with a foot oar which reminded me of the sailors on Inle Lake in Myanmar.
