BUENG KAN, Thailand – A striking natural phenomenon resembling giant “Naga eyes” has emerged at Phu Langka National Park, where rainwater trapped in natural sandstone hollows reflects sunlight during the rainy season. The Department of National Parks, Wildlife and Plant Conservation is inviting visitors to see the phenomenon on the rock platform near Naka Cave in Bueng Khong Long district, Bueng Kan province, upper northeastern Thailand. The unusual formations are created by natural geological processes. Rain and flowing water gradually erode the sandstone surface, forming bowl-shaped depressions and rock pools of different sizes.
During the rainy season, water collects inside the hollows. When sunlight hits the pools, the reflective surface creates striking patterns resembling large eyes on the rock, earning the formations the nickname “Naga Eyes.” Officials said the phenomenon highlights the area’s geological character while offering visitors another seasonal attraction at Naka Cave. The department is promoting the site as an example of nature-based tourism, encouraging visitors to experience the landscape while helping preserve the national park’s natural environment.
