A detailed guide to hiking the Naga Cave, combining physical challenges with mythical belief, along with tips for the best experience.

In 2020, the discovery of Naga Cave in Thailand’s Phu Langka National Park captured the public’s imagination. This national park is located across two provinces, Nakhon Phanom and Bueng Kan. While Naga cave is in Pho Mak Khaeng, Bueng Khong Long District, Bueng Kan, this new attraction showcases rock formations that resemble scales of the mythical giant serpent known as Naga.

According to park officials, these “snake scales” are approximately 100,000 years old and are formed from rock that has cracked under sharp temperature changes between day and night, with water erosion shaping these cracks to mimic the appearance of snake scales.

Why It Remains the Hot Spot Up Until Now

The cave continues to fascinate due to its mix of natural beauty and local mythology. Legend has it that Pu U Lue Nakrat, cursed to become a Naga and imprisoned, would be freed and the area there would be known and prosper only after a decade, coinciding with the 10th anniversary of the founding of Bueng Kan province in 2020. This tale fuels the cave’s popularity, and word spread through personal beliefs, leading to its continued fame.

Visiting Naga Cave

Naga Cave is accessible daily unless heavy rain poses risks. The journey from the starting point to the cave spans about 1,400 metres, involving a natural trail with stairs and earthen paths. Some sections require the aid of a rope to navigate. The round trip takes roughly 4-5 hours and is recommended for those in good physical condition. It is not recommended for pregnant individuals or those with certain medical conditions.

3 Ways to Reach Naga Cave

2. Take a tour bus to Bueng Kan, and then drive to Phu Langka National Park.

3. Drive there directly if you have a personal vehicle.
