Leaving Nakhon Nayok, the landscape is dominated by the Sankamphaeng Range, part of Khao Yai National Park, a UNESCO World Heritage Site. The park's lush forests and waterfalls, such as the 80-meter-tall Heo Narok, are visible from the highway.

Local commerce along the way includes roadside fruit stalls selling oranges and pomelos from Nakhon Nayok, and silk weaving communities near Chaiyaphum. For authentic Isan culture, the night market in Khon Kaen is a must-stop, offering food, crafts, and live music.
