Naka Cave is located within Phu Langka National Park in Bueng Kan Province, along a challenging uphill trail of 1.4–2 km. The route involves steep stairways and rope-assisted climbs, taking around 4–6 hours round trip.

Inside the cave, key spots include the naga head formation, realistic scale-like textures across the rock, and the dazzling Sun Crack, where natural light pierces through dramatic rock fissures.

According to local legends, this is where a naga was cursed and turned to stone. Believers and pilgrims travel here to pay respect and seek blessings.

Visitor access is limited to 350–1,000 people per day depending on the season. All groups are led by licensed local guides (about 10 persons per group), who share stories, provide safety, and guide the hike.

Visitors often describe it as a spiritual journey requiring both physical and mental strength. The atmosphere is peaceful and empowering, offering a rare connection between nature and faith.
