N.C. Gen. Stat. § 14-159.23: Limitation of liability of owners and agents.

The owner of a cave, and his agents and employees, shall not be liable for any injury to, or for the death of any person, or for any loss or damage to property, by reason of any act or omission unless it is established that the injury, death, loss, or damage occurred as a result of gross negligence, wanton conduct, or intentional wrongdoing. The limitation of liability provided by this section applies only with respect to injury, death, loss, or damage occurring within a cave, or in connection with entry into or exit from a cave, and applies only with respect to persons to whom no charge has been made for admission to the cave. (1987, c. 449.)
