Tham Phraya Nakhon Cave has a rich history that dates back to the reign of King Rama V in the late 19th century. The King was a frequent visitor to the area, and he discovered the cave by chance during one of his hunting expeditions. Impressed by the natural beauty of the cave, the King ordered the construction of a pavilion inside the cave, which was completed in 1890. The pavilion, called Kuha Karuhas, became a popular spot for the King and his guests to relax and admire the beauty of the cave.

Today, Kuha Karuhas is one of the most iconic attractions of Tham Phraya Nakhon Cave. The pavilion is located in the second chamber of the cave, and it is illuminated by natural light that filters through a hole in the roof. The light creates a stunning effect that highlights the beauty of the pavilion and the natural formations around it.
