One landmark that should not be missed when visiting Nakhon Nayok is the Khun Dan Prakarn Chon Dam. This impressive structure channels water from the waterfalls of Heo Narok in Khao Yai National Park, storing it before directing it to the Nakhon Nayok River. The beauty of the dam lies in the views from its crest, offering visitors breathtaking panoramas surrounded by stunning mountains, as well as high-angle shots of the reservoir below. The dam's crest also provides a romantic setting for cycling while waiting for the sunset. Additionally, the lower part of the dam features seasonal water diversions during various festivals, allowing tourists to enjoy fun activities, complete with relaxing resting spots.
