The Khorat Geopark is not only a treasure trove of ancient fossils and rocks but also a living sanctuary of natural heritage. The Chaloem Phra Kiat Banyan Tree stands as a magnificent example of the profound relationship between the ecosystem and the local way of life.
Often called "Sai Ngam" (Beautiful Banyan) by the locals, this single banyan tree is estimated to be around 200 years old. Located on the banks of the Mun River in the Chaloem Phra Kiat district, the tree has a unique characteristic: its massive aerial roots have grown downwards to form new trunks, creating a sprawling canopy that covers an area of more than two acres. This makes the area a lush, cool, and self-contained mini-forest. Beyond providing a huge amount of shade, this giant banyan serves as a vital habitat for various bird species and small animals that rely on its yellow figs for sustenance. At night, the area beneath the tree is also home to a large population of fireflies that light up the darkness, creating a breathtaking and magical sight. The continuous growth and vitality of this tree serve as a testament to the rich biodiversity of the Mun River ecosystem, which is a key component of the Khorat Geopark's natural legacy.
Beyond its natural significance, the Chaloem Phra Kiat Banyan Tree has long served as a spiritual and economic heart for the surrounding community. Local villagers have built bamboo walkways and nature trails, allowing visitors to get up close to the tree's grandeur. The area is also home to the Lan Sai Market, a community-based market that promotes ecotourism and preserves local traditions. This market provides a platform for villagers to sell local products and agricultural goods, generating income and sustaining the local economy. Moreover, the tree itself is a powerful symbol of the deep bond between the people and nature. It is a site where local religious rituals and traditions, passed down through generations, are still practiced. The Chaloem Phra Kiat Banyan Tree is therefore a perfect example of the crucial link between natural and cultural heritage, a central tenet of the UNESCO Global Geopark philosophy.
The Khorat Geopark is not only home to significant cultural heritage but also a wealth of beautiful natural heritage that reflects a long geological history. Wang Naen Waterfall, located in Sung Noen district, is one of the most prominent and well-preserved examples of this natural legacy. The waterfall was formed by the erosion of the Lam Takhong River as it cut through layers of late Cretaceous sandstone and mudstone, which are part of the distinguished Khorat Group rock formation. The waterfall features a series of cascading rock layers, creating beautiful small falls and rapids, as well as clear water pools perfect for year-round recreation. A special characteristic of Wang Naen Waterfall is the clear visibility of the alternating layers of sandstone and reddish mudstone. This serves as vital evidence of the ancient paleo-environment—a setting for sediment accumulation and home to countless prehistoric organisms. A visit to this site is like traveling back in time to explore the world as it was millions of years ago, offering a truly tangible geological lesson.
While classified as natural heritage, the area around Wang Naen Waterfall is also deeply intertwined with local cultural values, particularly in the dimensions of beliefs and the historical way of life. The name "Wang Naen" itself has a history linked to Buddhism and the traditional life of monks who practiced meditation in this serene area since ancient times. This natural landscape has long been known as a peaceful and tranquil place, suitable for spiritual retreat, which aligns with the "Route of Faith" of the Khorat people who often used natural spaces for their spiritual practices. Furthermore, the waterfall and its stream have been crucial water sources sustaining local communities, leading to the establishment and development of a lifestyle that relies sustainably on nature. These values reflect the strong relationship between nature, beliefs, and the culture of the Khorat people, which is a central theme of ecotourism within the Khorat Geopark.
