Pha Iang Waterfall is located within Tat Ton National Park in Chaiyaphum Province. It is formed by the Chiloang Stream flowing through a highly fertile watershed forest area.The waterfall area features a distinctive geological structure of naturally slanted rock layers. As a result, the water does not fall vertically like a typical waterfall, but instead spreads out over the rock surface in thin sheets and splits into multiple small streams, creating a beautiful and unique curtain-like flow.The downstream pool is formed by long-term erosion from the water flow, resulting in a shallow to moderately deep basin. The bottom consists of pebbles, rounded stones, and fine sand, and visitors can swim in certain areas where the current is not strong.

The surrounding environment is a mixed deciduous forest and dry evergreen forest, maintaining rich biodiversity. Medium to large trees grow densely, while understory plants such as ferns and moss thrive on moist rock surfaces. Small wildlife such as birds, butterflies, and amphibians can also be found in the area, especially in the early morning and late afternoon when humidity is high and the weather is cool.The waterfall’s appearance changes with the seasons. During the rainy season, it has a strong water flow forming a continuous curtain along the cliff. In the late rainy to early winter season, the water becomes clearer and more suitable for visiting. During the dry season, the rock layers become clearly visible, making it ideal for geological observation.

Access to the waterfall requires a short walk along a natural shaded trail, allowing visitors to experience the forest atmosphere and natural sounds up close. Pha Iang Waterfall is therefore both a natural tourist attraction and an important ecological area that helps maintain the moisture of the Chiloang watershed and supports environmental balance in the surrounding area.
