Tham Phi Hua To, Krabi.

Tham Phi Hua To A large cave hidden in a solitary limestone mountain, surrounded by lush mangrove forests. What sets it apart from other caves is the presence of over 3,000-year-old wall paintings scattered throughout, divided into 23 groups with a total of 238 paintings. The impressive part is that you don't have to observe them from the middle of the sea like in other places; you can stand and observe them up close. Additionally, ancient artifacts and human skeletons have been found here, providing evidence that this was another dwelling place for Stone Age humans.
