THE ROUTE

Newly opened, undeveloped passages

This tour moves through a recently opened section of the cavern on an undeveloped trail, giving guests a raw, close‑quarters experience of parts of the cave that aren’t part of the main show route.

THE FORMATIONS

Delicate cave features by flashlight

Guests are given a flashlight to examine fragile speleothems up close; the guided format keeps the group tight and focused on the subtle beauty of the rockwork.

THE DEMAND

Rugged, intimate and physically engaged

The route is rugged and intimate rather than fully developed—expect an active walk and strict footwear requirements; the tour’s small‑scale nature emphasizes exploration over comfort.
