Dvaravati U Thong Ecological Stone Garden Buddhist Park, commonly known as “Phu Hang Nak Natural Stone Garden,” is an outstanding eco-historical attraction located within the ancient city of U Thong in Suphan Buri Province. This area holds significant natural and archaeological value, featuring groups of sandstone and limestone formations that have been shaped by natural erosion over millions of years, resulting in extraordinary rock formations that resemble sculptures created by nature itself.

Phu Hang Nak is closely connected to the Dvaravati civilization, one of the most important ancient cultures of the Suvarnabhumi region. Archaeological surveys and excavations in the surrounding area have revealed ancient stupa foundations and historical remains, indicating that this site once served as a sacred place and an important strategic location for religious activities and early settlements in the past.

The most iconic landmark of Phu Hang Nak is the “Hidden City Gate,” a narrow rock passage formed naturally by two massive rocks leaning against each other. Visitors can follow the nature study trail to explore a variety of uniquely shaped rock formations that spark the imagination, such as rocks resembling a Naga serpent, a turtle, and a formation locally known as the “Emperor’s Throne.” Each spot carries its own distinctive character and local stories.

Along the trail, visitors will experience the richness of the ecosystem and encounter ancient and rare plant species, including centuries-old Chan Pha trees growing from rock crevices, wild cycads regarded as prehistoric plants, and a variety of seasonal wildflowers that add freshness and color to the landscape of the stone garden.

For hikers and nature lovers, Phu Hang Nak offers trails of varying difficulty levels, from easy walking paths to routes leading up to scenic viewpoints at the highest point of the park. From this vantage point, visitors can enjoy sweeping panoramic views of U Thong District and the surrounding countryside. The quiet and solemn atmosphere of the stone garden provides a travel experience that differs from typical temple visits, offering deeper meaning and tranquility.

Phu Hang Nak Natural Stone Garden is therefore a destination where Buddhist beliefs, ancient history, and the power of nature blend harmoniously. It is ideal for those seeking knowledge, exploration, and a deeper connection with both the natural world and cultural heritage.

Visitors are warmly invited to uncover hidden secrets beneath the shade of trees and million-year-old rocks, breathe in the fresh air, and admire the exquisite artistry crafted by nature at Phu Hang Nak Natural Stone Garden.
