Wat Khao Tham Bunnak is an important spiritual center for the people of Takli District and Buddhist devotees from across Thailand. The temple stands out for its deep religious history and strong spiritual atmosphere that has been preserved for generations.

Luang Pu Si Chanthasiri

Luang Pu Si was one of the longest-living monks in Thai Buddhist history, born during the reign of King Rama III and passing away in the reign of King Rama IX, reaching the extraordinary age of 128 years.
Today, his incorruptible body is enshrined in a glass coffin within a ceremonial pavilion, allowing devotees to pay respect, seek blessings, and reflect upon his profound virtues.

Tham Bunnak Cave

This natural limestone cave features natural ventilation shafts, keeping the interior cool and comfortable throughout the year. It once served as a place where Luang Pu Si practiced meditation and ascetic discipline.
Inside the cave are multiple Buddha images and a replica of the Buddha’s footprint, making it an ideal place for meditation, contemplation, and inner peace.

Legends and Beliefs

Local belief holds that the cave is inhabited by a Phaya Naga (serpent deity) who protected and attended Luang Pu Si during his meditation retreats.
As a result, Wat Khao Tham Bunnak is regarded as a place of mystical power, sacred energy, and deep faith, especially among devotees of Luang Pu Si’s teachings and sacred amulets.
