"Department of National Parks, Wildlife and Plant Conservation" is the agency involved here., invites visitors to experience the wonder, the "Naga's Eye", a natural rock pool illuminated by sunlight during the rainy season at Phu Langka National Park.
On 17 August 2026, the Facebook page ofthe Department of National Parks, Wildlife and Plant Conservationposted an invitation encouraging tourists to experience a natural wonder on the rocky plateau near Naga Cave, Phu Langka National Park, Bueng Khong Long District, Bueng Kan Province. They highlighted the rainy season phenomenon where rainwater collects in natural rock pools and reflects sunlight to sparkle like the "Naga's Eye," showcasing the area's geological richness and aiming to promote eco-tourism.
This phenomenon results from geological processes where water and rain erode the sandstone plateau forming various sizes of rock pools called Kumpa Bok. During the rainy season, water trapped in these pools reacts with sunlight to create beautiful, large eye-like reflections on the rock surface, becoming a popular highlight for visitors to Naga Cave.
Atthapol Charoenchansa, Director-General of the Department of National Parks, Wildlife and Plant Conservation, explained that this phenomenon reflects the natural wonder of Phu Langka National Park. Beyond beliefs and faith, the site holds significant geological and natural importance. The department is committed to balanced management and requests visitors to observe respectfully, avoiding touching, marking, or damaging the natural resources to preserve this beauty sustainably.
Meanwhile, Aksorn Manawong, head of Phu Langka National Park, added that this spot is a key highlight along the Naga Cave trail. Visitors can normally hike to see it. The pool is approximately 1.5–2 meters deep, holding water almost year-round, with levels gradually decreasing during the dry season.
The most beautiful time to visit is the rainy season from May to October when the pool is full and sunlight hits at the right angle, creating stunning images. After October, water levels drop and leaves accumulate, lessening the visual appeal. Therefore, the rainy season is the best time for visitors to experience this attraction.
