As you tour the caverns, you will be travelling from chamber to chamber via lighted paths and the occasional stairway. This stairway passes by the Organ Loft,” and leads up to the “Angel Wings.” As most speleothems are delicate and brittle, it is very important that you not touch them as you make your way through the caverns.
