You cannot get an unguided tour but you can purchase a full cave tour and explore the entire cavern with a tour guide. Its more in depth and you actually get to go off the normal cave trail.
No you can't, guided tour is the only option or you can go for an advance level of cave exploration which needs to be planned but even that is led by one of their crew member.
No have to have a guide
Cavern no but there is a unguided tour around the cavern on a trail path
Unfortunately, they won't let you.
