Okay, the user wants me to translate "cave explorers" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without any explanations.
So, "cave explorers" is in English, so I need to translate it. The direct translation would be "ผู้สำรวจถ้ำ" which means people who explore caves. I should make sure there's no existing Thai text that's already correct. Since the input is in English, I proceed with the translation. No need to add anything else. Just output "ผู้สำรวจถ้ำ".
