Than Ngam Park, situated within the Thap Kung-Huai Suea National Forest Reserve in Nong Saeng District, Udon Thani Province, is a highly favored ecological and recreational site for both locals and tourists seeking tranquility. The park forms a part of the Phu Phan mountain range, characterized by its outstanding geological features as a relatively well-preserved dry dipterocarp and mixed deciduous forest, encircled by intricate mountain ridges.

The core attraction of the park is the Huai Suea Stream, a small waterway that flows over massive sandstone formations and dramatically spreads out into a spectacular, wide stone terrace (Larn Hin). This expansive terrace is the most popular area for relaxation. The stone surface is layered, featuring natural rock pools and crevices that collect water, making them perfect for wading or soaking during the dry season or when the water flow is mild. The continuous water erosion over time has sculpted the rock formations into unique and fascinating natural shapes.

Beyond the stream and stone terrace, the vicinity hosts important sites of religious belief and worship, such as Tham Phet Nakha (Phet Nakha Cave). This is a moderately sized and easily accessible cave, housing Buddha images and serving as a meditation spot, thus establishing Than Ngam Park not only as a natural attraction but also as a spiritual center for devotees. Exploring the park's perimeter also reveals small seasonal waterfalls that emerge along the rock faces during the rainy season, offering fresh air, cooling mist, and picturesque photo opportunities.

Regarding facilities, Than Ngam Park maintains a high degree of natural integrity, offering only basic amenities such as restrooms and parking. There are no large restaurants or luxury accommodations. Most visitors prefer to bring their own mats, food, and drinks for a picnic on the stone terrace, truly immersing themselves in the local way of relaxation. It is also a safe location for camping (contacting the park authorities beforehand is advised). Maintaining cleanliness and caring for the environment are paramount responsibilities for all visitors to this natural sanctuary.
