you will follow your tributary and see it merge with a few others to slowly form the Nakon Nayok River. The waterways are quite narrow at some points so larger boats cannot make the journey. There are a few gentle rapids but nothing very scary. There are many twists and turns as the streams meander through the peaceful Nakon Nayok countryside. You can slip off the boat for a swim in the river as you go. It all makes for a very pleasant couple of hours entertainment.
