Bring a light jacket! It can get chilly inside the cave, even in summer. I wasn't expecting the temperature drop and regretted not preparing.

Don't forget your camera! The rock formations are stunning, but be sure to ask your guide about the best spots for photos—some angles really make the experience pop!

Consider booking your tickets online ahead of time. I saved a few bucks that way and avoided long lines at the entrance!
