1. Phanom Rung Historical Park
Phanom Rung Historical Park places a Khmer sanctuary on an ancient volcanic hill. The approach, stone doorways and carved details make it rewarding to explore slowly. For example, stop along the main route to notice how the buildings frame one another. This is a strong choice for architecture and history.
First, allow time for the walk and changes of level. Bring water and follow the marked route around the monument. Afterwards, consider nearby Prasat Mueang Tam if your transport and energy allow a second heritage stop.
