Interesting sites within the wildlife sanctuary include: Khong Chai Mountain, situated in Lan Sak Subbdistrict, serves as the headquarters of the Tham Prathun Non-Hunting Area. Rising 353 metres above sea level, the mountain features numerous caves of varying sizes. These caves contain stone tools and pottery shards, indicating prehistoric human habitation. The caves are also home to a large bat colony, visible around 18.00 hrs. Tat Forest Cave, located in Tambon Thung Nang Ngam, was discovered in 1979 by Phra Khru Santhithamkosol (Luang Pho Thongyot), the abbot of Wat Tham Thong. The cave is filled with Tat trees (Areaga penata) and was declared a conservation area due to its rich biodiversity, including rare species of flora and fauna; such as, Fishtail Palm (Caryota mitis Lour.), Thick-billed Green Pigeon (Treron curvirostra), bats, and Balanophora fungosa J.R.Forst. & G.Forst. The cave entrance is a dark passage approximately 50 metres long, leading to a large chamber illuminated by natural light. The forest inside resembles a primeval jungle, making it ideal for nature walks. The round-trip walking distance is about 700 metres. Khao Plara, located on the border between Ban Huai So, Lan Sak District, and Khao Bang Kraek Subdistrict, Nong Chang District, stands 598 metres tall. The lush forest requires a three-hour trek (distance of 900 metres) to reach the summit, offering stunning panoramic views. The west-facing cliff is adorned with 40 prehistoric paintings, dating back over 3,000 years. They were drawn with black and red lines along the cliff for a total distance of 9 metres, depicting human and animal figures, providing insights into ancient community life in Uthai Thani Province. Visitors must coordinate with a guide before embarking on the trek. It is advisable to bring drinking water and wear sturdy hiking shoes due to the rocky and slippery terrain.
