While Phraya Nakhon Cave is the most famous cave in Khao Sam Roi Yot National Park, Tham Sai Cave, located on a hill near Ban Khung Tanot, about 9 km from the National Park Administration, is also worth seeing. Its magnificent stalactites form an almost waterfall-like effect in the main chamber, which is illuminated by a skylight. Access to the cave is via a strenuous hike through the forest. Although it is only 280 meters long, the path is not easy. The cave is quite dark and has no lighting, so I strongly recommend bringing a good flashlight, even though the most interesting part is naturally illuminated through an opening. Note that there is a third well-known cave in the park, Kaew Cave. However, do not go there without a guide, as there have been several accidents in the past. I personally decided against visiting this cave.

Sai Cave is part of Khao Sam Roi Yot National Park. To get there, you need an entrance ticket for the park, or you can buy one at the kiosk in the parking lot.

It is essential to be transported in order to reach the starting point of the path leading to the Sai Cave.
